Manoeuvring through menus The RFM300-T Series Refractometer features a capacitive, high- resolution touchscreen display. On-screen buttons can be easily used by simply touching the display. A compatible stylus can also be used, as supplied with the instrument.
Page 14
Many buttons feature a quick select option, indicated by the two arrows on the right of the button. Simply touch either arrow to cycle through the possible settings. When in a menu, the Quit and Home buttons become available. Press the Quit Button to return to the previous menu. Any changes made will be saved.
Setup Wizard When switching on for the first time, after the instrument has completed its startup procedures, the Setup Wizard will appear. First select the desired language. A list of different options will then appear. • Copy user guides and PC software to USB: Makes copies of all user guides and PC software compatible with the instrument to a removable USB storage device.
Measurement Display From the Measurement Display readings can be taken, viewed and saved. Quick access to all the frequently used features of the instrument is also available. Title bar Reading display and data Reading configuration Action buttons Menu buttons Page 14 RFM300-T 19-461’02 Rev.
Title Bar The title bar contains several elements that will be displayed on every screen. 1. Title: Current location within the instrument’s menu structure. The colour of the title bar will change depending on the current operation. Red: In the Main Menu structure. This indicates that changes will be made to the instrument’s settings.
Page 18
4. Temperature control status: Displays the stability status, prism set temperature and current prism temperature. The colour and status symbol will change depending on the set-point temperature and the measured temperature. • Temperature stable The tick indicates that the measured prism temperature (second value) is stable to within ±0.05°C of the set-point temperature (first value).
Reading display and data 1. Reading result: After taking a reading, the final result will be displayed here. The result will be displayed in the units set in the Mode/Method, shown in the reading configuration section of the Measurement Display. Warning and alert messages will also appear here.
Reading configuration 1. Reading Configuration Panel: Displays the measurement settings for the currently displayed reading or, if a result is not currently displayed, the settings to be used for the next reading. It also allows for quick changes to the Basic reading settings, see Using the Reading Configuration Panel, Page 21.
2. Record button: If a result has yet to be printed or saved and a printer is set, the record icon will appear grey. Pushing the button will record the result to the Reading Log (Page 35) or printer depending on the print settings, see Page 30.
Measurement settings The measurement settings affect how a reading is collected and presented. If different sets of measurement settings are required then Methods can be enabled. For simplicity, the instrument is supplied in Mode operation. Changing settings To change measurement settings press the orange Mode button. The Mode Configuration is divided into two screens with Basic and Advanced settings.
Using the Reading Configuration Panel Basic settings can be changed with the Reading Configuration Panel. To change a setting, touch and hold the panel and an arrow will appear next to the selected item. If the wrong item is selected, the user can slide their finger up or down until the required item is highlighted.
Set Temp (temperature control set-point) The temperature control system in the instrument can be set over a wide range of temperatures. In many situations, it is likely that all samples will be measured at the same temperature, e.g. 20°C for a bottling plant or 70°C for a preserves factory.
Page 25
Repeatability will take readings continuously until a number of readings are below a specified range. The range can be set on the reading value, temperature or Quality. Example: A set of consecutive readings is shown below. The displayed result will vary depending on the set repeatability condition. Reading no.
Limits Limits notify users if readings have fallen outside set criteria. If the measured values fall outside the set Limit the Reading Display will turn red and a line will be drawn through the result. If the measured values are within the set Limits the Reading Display will turn green.
Resolution The instrument has settings for both temperature and reading resolution. The temperature can be shown to 1 (low) or 2 (high) decimal places. Each measurement scale has a number of decimal places assigned to it that is appropriate for that scale. Changing the resolution adjusts the scale’s assigned decimal places, i.e.
Using Methods A Method is a named set of measurement settings. They include all the settings necessary for the instrument to take and check a particular sample. If the complete range of product types that is to be measured with the refractometer requires the same measurement settings then using the Mode Menu is most suitable.
Calibration and Reading Allow the instrument to stabilise for at least 30 minutes after switching on before taking accurate readings. Zeroing the instrument The instrument should be Zeroed regularly to ensure accurate readings. Any sample can be used to set Zero but typically distilled water is used. To Zero the instrument press the Zero button on the Measurement Display or access Zero via the Calibration Menu in the Main Menu.
Auto Zero When the instrument is turned on or the set-point temperature is changed a Zero calibration will be requested by the instrument. This is to ensure that readings are as accurate as possible. Whilst the temperature stabilises the Reading Result section of the screen will display a warning message.
Lower the presser, if auto-single or continuous reading recurrence (see Page 51) are active readings will be initiated, otherwise press the Read button. The instrument will display a progress bar dependant on the stability criteria set (see Page 22) whilst the required measurements are taken. The reading will then be displayed using the scales and temperature compensations specified in the Mode Menu or current Method as shown on the Reading Configuration Panel.
Saving results To access the Recording Menu to set up printing and saving, press Menu then select: • 3. Setup • 5. Recording Alternatively hold down the Record button on the Measurement Display for several seconds. Set the print mode The print mode (option 1) has several different settings: Mode Function...
Print formats There are a number of different print formats. Several different printer types are available from Bellingham + Stanley, see the Accessories section. The print format is set in option 2 of the Recording Menu. Printer Description Result will not be sent to a printer, this format can be used if only CSV results are required.
Batch codes The instrument can request batch codes in the following formats: Setting Description The instrument will not request a batch code. number Number from 0 to 32000. text 14 character alpha-numeric string. The date followed by an auto increasing number from 0 to 9999, in the format of: yymmddnnnn dateinc...
Statistics print mode If the print mode (see Page 30) is set to statistics, a group of up to 10 readings can be temporarily logged together and a statistical analysis carried out upon the results. To perform a statistical reading set, prepare and read a sample as normal.
Page 36
• 5. Info button: Displays a list of the individual readings • 6. Read button: Stores the current statistics in memory and initiates the next reading. After more readings are taken any that are recorded will be included in the statistical analysis. 7.
Data Menu The instrument has two separate logs for storing data. This data will be held in the instrument whether the power is on or off and can be downloaded to a computer using the PC Data Acquisition Program, downloadable from the instrument or available for free at the Bellingham + Stanley website, or using a USB removable storage device.
The System Log The System Log maintains a record of all changes and adjustments made to the instrument by its users. This will include each Zero and Span calibration, changes to the setup, configuration and Methods. The System Log functions in the same way as the Reading Log however instead of filtering by date the filter is based on the event type.
PDF and FTP If a large number of PDFs have built up in the instrument, transfer via USB could take several minutes. In this case it may be preferable to transfer PDFs from the instrument via FTP. Additionally, the PDFs can be viewed whilst still in the instrument using FTP.
Methods A Method is a defined set of measurement settings. This allows for measurement settings to be quickly changed between frequently used configurations or for reading different products with specific test requirements. For example, if a range of different soft drinks is regularly measured a Method could be created for each with the display set to show whether each product is within its set tolerance using the limits system.
Selection type Before reading a sample, the relevant Method should be selected by pressing the Method button on the Measurement Display. Holding down the Method button for several seconds will enable editing of the currently displayed Method, a login from a user with Setup rights will be required if PINs are active.
Adding a new Method With Methods switched on, pressing Quit from the Method Settings menu will show a list of current Methods. This list will be shown first when re-entering Methods at a later time. To add a new Method, press the Add new... button. Enter the Method name, this could be a common name, such as mint oil or orange oil, a trade name or a product reference code.
User accessibility RFID tags offer rapid user clearance, see Page 49. Access to the instrument’s functions and Menus can be restricted, with the sophistication of the protection set to match the operating environment. There are a range of security features that can be activated to preset levels for convenience or customised to user preference.
Page 45
• Keep Logged In (0 (off) to 300 seconds) This option specifies how long a user is kept logged in for whilst idle before automatically being logged out. If set to 0, a user will be logged out on returning to the Measurement Display. Leaving the instrument logged in can lead to security issues as unauthorised use of the instrument could occur.
If the user entered their login details correctly a new PIN will be requested. The new PIN must be input twice to ensure no errors are made. After the PIN has changed, the instrument will continue to whatever was requested that required a login to access. Preset protection levels The preset protection levels use the following configurations of the above security features.
Page 47
• Medium This preset improves security by requiring the user to enter their username and then their PIN. This preset does not have features enabled that could increase administration overheads. Security feature Setting User Selection User and PIN PIN length Keep Logged In 30 secs Maximum PIN Age...
Users After setting the security level as required users can then be added. The current users are shown in the Users menu. There are three default users in the instrument. These users can only have their PINs changed or ID tags paired (see Page 49). Their set rights cannot be altered and have the following settings by default: Username administrator...
The different user rights give access to the following: Right User access If using the Mode Menu, users will be able to change the measurement settings. If Methods are active, Mode / Method users will be able to change Method but Method measurement settings cannot be changed.
Logging in/out If “user and PIN” is active, when a user tries to access a Menu, for example, the instrument will first request their username. If “remember last user” is active there may already be a username in the text box. After confirming username entry or if user selection is set to “PIN only”, the PIN entry screen will appear.
To log a user out simply touch anywhere on the title bar, the security icon will then turn orange and a logged out message will appear briefly. Logging out can also be performed by swiping an RFID tag. RFID Tags RFID (radio frequency identification) tags are used to wirelessly identify a user.
RFID tags can only be read when the instrument is showing the Measurement Display, when a PIN or username is requested, or when specifically prompted by the instrument. A flashing RFID icon will be shown on screen when tags can be scanned. To log in, simply swipe the RFID tag over the reader when required.
Reading setup In addition to the measurement settings there are several other factors that can affect how readings are taken. To access the Reading menu, press Menu, then select: • 3. Setup • 4. Reading Or hold the Read button on the Measurement Display for several seconds.
Application correction • Offset The instrument has the ability to apply a simple offset and scaling factor to results from each individual Method. This can be used, for example, to adjust the refractometer to give values equivalent to a reading taken on a density meter.
Reset will return the offset and scaler to the default values (0 and 1 respectively). With an offset correction applied, all readings taken with that Method will be displayed with an identifier on the Measurement Display. • Citric acid Acid correction allows for automatic correction of the effects of citric acid on readings.
Adding a library scale Press the Add new… button in the Scales List screen, then press From Library. The following scales can then be installed. Library Scale Title Scale name number Zeiss zeiss Oechsle (German) oechsle (de) Butyro butyro 42% Fructose 42% fructose 55% Fructose 55% fructose...
Adding a custom scale As well as the library scales, readings can be converted to any custom units. To set up a custom scale, press Add new... on the Scales list then select From Data. First, enter a unique name for the scale. Up to 16 characters can be used.
An Offset value is available in the Constants screen, this can be set to 0 although greater accuracy can be achieved when calculating a polynomial for a range starting at water by using an Offset of –1.33. Set the resolution to have the number of decimal places suitable for the accuracy required of the scale.

folder and placing compatible files within, it is possible to import files saved or created by other means • Network It is possible to import scales and temperature compensations to the instrument via a network. Connect to the instrument via FTP (see Page 37), create a folder called “Scales”...
Communications The instrument can save and print results in a number of different formats, see Page 30. Serial and USB printers available from Bellingham + Stanley will work on a plug and play basis, see the Accessories section at the rear of this User Guide. However, to print to a network printer its IP address will be required.
When CSV (Lims) mode is active, a CSV result is sent every time the Record button is pressed on the Measurement Display. This allows a result to be recorded as a CSV and by any selected printer simultaneously. Results in the Reading Log are also stored in CSV form and can be downloaded separately, see Page 36.
System settings To make changes to the system settings press Menu, then select: • 3. Setup • 6. System Language There are several language options available in the instrument by default. Select the required language and press Yes to confirm the change. If the language you require is not available, contact Bellingham + Stanley and we will do our best to accommodate your needs.
• Set Clock… Enter the time and date in the format displayed on screen, as specified in Date format. Use the arrow buttons to change the cursor position. Press ok when the clock is set to the correct time and date. Temperature control Under certain conditions it may be useful to disable the prism temperature control or disable the presser.

Select the instrument, by serial number, which has the settings required for the current instrument. A list of date and time stamped backups will then appear. Select the backup with the required settings. A backup of the current settings will be made in case the Clone needs to be undone, this will be labelled as an “autobackup”.
Maintenance Menu There are several options to help keep the instrument in good working order. To access the Maintenance Menu select option 4 in the Main Menu. Maintenance Report It is recommended that the instrument is regularly serviced by Bellingham + Stanley trained personnel.
Filter change The instrument is fitted with a replaceable filter on the cooling air inlet vent which will prevent airborne dust or grease entering the ducting and clogging the fans. Filters should be removed and replaced at regular intervals. The instrument must not be operated with blocked filters or without the filters in place.
Backup The Backup option creates a copy of all the settings changed in the instrument. Using Clone (see Page 61) these changes can be reloaded at a later date to undo accidental changes or deletions. Alternatively, the settings can be Cloned to another instrument. This is useful if multiple RFM300-Ts are available for use.
Information and Help From the Main Menu the Help Menu can be accessed (option 5). From here information regarding the instrument’s software, hardware and network configuration can be seen and printed. This is useful to have available when contacting Bellingham + Stanley for assistance and can be printed to the selected printer.
