Page 5: Quadoptix™ Technology
QUADOPTIX™ TECHNOLOGY The Palintest Compact Turbimeter utilizes QuadoptiX™ technology for turbidity measurement – a sophisticated optical approach designed to ensure turbidity measure- ments are as accurate and repeatable as possible in even the most challenging circumstances. Turbidity measurements are carried out by analysis of light scattered at 90°... -

Page 8: Battery Life/Replacement
Battery Life/Replacement Your Compact Turbimeter is supplied with fresh batteries that will be suitable for at least 150 hours of use. Changing batteries carried through compartment on the rear of the instrument. Two ‘AA’ 1.5V batteries are required. Current battery status is displayed on the screen to assist in power management. -
Page 9: System Menu
SYSTEM MENU The System menu allows the user to set the Compact Turbimeter preferences and review results and calibration data. Select ‘Results’ or ‘Calibrations’. Once the log has been chosen, select ‘View’ or ‘Clear’. The ‘Readings’ log holds up to 100 data points with date, time, Sample ID, Operator ID, Reading Mode and Result. -
Page 10: Sample Id
When the correct character is shown, press and hold the [+] key for one second to move to the next character. Correct mistakes by holding the [Del] key for one second. Complete the process by pressing ‘Done’ briefly. Select ‘OK’ to accept the entry or Edit to modify the entry. -
Page 11: Units
Units Results can be displayed in NTU, FTU and FNU. Language Select English, French, German, Spanish or Italian and press ‘OK’ to switch to alternative languages. Set Time Increase/decrease the time by using the Up/Down buttons. When the correct time is shown select ‘OK’. Set Date Increase/decrease the date by using the Up/Down buttons. - Page 12 The Compact Turbimeter will maintain the current status until changed. Start Page The ‘Start Page’ allows the user to define a choice of initial screens/modes on powering the Compact Turbimeter. To change start page, highlight the favoured choice for initial screen – Mode Menu, Normal Reading Mode or Last Reading Mode.

Page 13: Reading Menu
READING MENU When taking readings ensure the cuvette is free from dirt, dust and condensation using the supplied lint-free cloths. Ensure the light cap is in place to prevent stray light from adversely affecting readings. If no light cap is fitted or the sample cuvette is not correctly inserted Error 107: Blanking Error will be reported. -
Page 14: Taking Readings
Total Suspended Solids – The relationship between turbidity and suspended solids can be approximated with correlated data. The QuadoptiX™ bench provides the performance required to produce reliable data for suspended solids, based on calculated factors (slope and offset) for turbidity versus suspended solids. Default factors are not possible due to the unique variety of size, shape and reflectivity of individual sample matrices. - Page 15 Average Mode Choose ‘Reading’ mode, select ‘Average’ and press ‘OK’. Select the number of readings required for the averaging function :- Short Average – 3 consecutive readings Medium Average – 6 consecutive readings Long Average – 12 consecutive readings Insert the sample with the orientation mark facing forward and press ‘Read’.

To cease measurement, press ‘Back’ at any time. To index a cuvette, insert the sample cuvette with the orientation mark facing forward. Systematically rotate the sample cuvette 45° at a time and record the position of the lowest value. This is the optimal cuvette alignment for low turbidity measurement. -
Page 17: Calibration Menu
CALIBRATION MENU The Compact Turbimeter is delivered with a stored calibration carried out on primary Formazin standards and validated as part of the production process. For field use, a set of calibration standards are provided as part of the kit. Recalibration is only required if the standards provided show an unacceptable level of variation from the stated values on read-back. - Page 18 Total Suspended Solids – When using the Turbimeter in Total Suspended Solids Reading mode, a calibration is required to set the relationship between the measured turbidity values and the ‘true’ suspended solids value, determined by gravimetric methods. This calibration can either be an assigned series of values from the results log or a simple algorithm with factors provided by the user.
- Page 19 Calibrating the Compact Turbimeter SDVB Select Calibration and press ‘OK’. Choose ‘SDVB’ and press ‘OK’. Select the lowest (0.05 – 0.15) NTU standard and insert into the sample chamber with the orientation mark facing forward. Use the Up/Down buttons to adjust the value on screen to that on the standard and press ‘Read’.
- Page 20 The time, date and Operator ID are stored in the calibration log for GLP compliance (see Page 9, System menu). Formazin Select Calibration and press ‘OK’. Choose ‘Formazin’ and press ‘OK’. Acceptable fresh Formazin standards should be prepared within the following ranges: 0.01 –...

Page 21: Total Suspended Solids - Correlation
Press ‘Back’ to leave the calibration process and return to the Calibration menu. To cease calibration during the data capture phase press ‘Cancel’. To cease the calibration process at any step, press ‘Back’ (calibration data will be discarded). The time, date and Operator ID are stored in the calibration log for GLP compliance (see Page 9, System menu). -
Page 22: Total Suspended Solids - Factor
Press ‘Select’ to enter the concentration of suspended solids determined externally using the Up/Down buttons. When data entry is complete press ‘Done’ and the slope/intercept will be calculated and shown auto- matically. Data points can be edited or deleted as required. Highlight the data point of interest and select ‘Edit’... -
Page 23: Restore Factory Calibration
Highlight ‘Intercept’ and press ‘OK’ (in many cases the intercept will be zero but for straight line fitting an offset will sometimes be required). Use the Up/Down buttons to enter the intercept. Select ‘Add’ to recall data points from memory for which a correlated suspended solids value has been measured. -
Page 24: Care And Maintenance
CARE AND MAINTENANCE The Compact Turbimeter has been tested for IP67 compliance so accidental immersion will not damage the internal components. Sample cuvette should be clean and dry prior to insertion into the sample holder. Lint free cloths are provided for this purpose. Silicon oil is also present to use on scratched cuvette surfaces. - Page 25 Palintest Ltd. No prescribed maintenance intervals are possible due to the high dependence on frequency of use, types of samples and conditions and user protocol. Service and maintenance is available via authorised service centres or direct from Palintest Ltd.

Page 26: Troubleshooting
TROUBLESHOOTING The Compact Turbimeter has internal diagnostics to advise on some issues as follows :- Error 100 – Measurement Off-Scale The reading is above 1050 NTU. Dilute using the provided PT 512 Dilution Tube and clean water and re-measure. Error 101 – Incorrect Standard The standard inserted is either the incorrect value or is longer within... - Page 27 Error 111 – Battery Critical Battery level is critically low and the instrument will automatically shut down immediately to ensure all data is written to the memory correctly. Other more general issues that arise may be as follows:- Readings are consistently higher than expected Check the sample cuvette for dirt, scratches and marks.
- Page 28 Gently clean the optical chamber using a soft, damp cloth. Do not use abrasive materials. Recalibrate the meter using the supplied standards to remove the offset. Readings are unstable/variable Turbidity is a measurement of scattered light with the source of scattering being microscopic and larger solids present in the sample.
