Page 4: Warnings
Warnings Please carefully read this manual and all warnings. Install the meter ONLY when you are sure that you’ve covered all aspects. Where the product is intended for “UL” installations, removal or addition of option boards is not permitted. Check that the model number and supply voltage suit your application before you install the meter. -

Introduction Please contact us if you need help, if you have a complaint, or if you have suggestions to help us improve our products or services. If you contact us about a product you already have, please tell us the full model number and serial number, so that we can give you accurate and fast help. -
Page 6: General Description
General Description This series of meters accepts industrial sensors to allow various physical measurements to be made, such a weight, temperature, pressure, humidity etc. Different models are available for different sensor types. The main function of this series is to give a numeric readout of the variable being monitored. Most models include an excitation power output, to power the sensor directly. -
Page 7: Panel Mounting & Installation - Class
Panel Mounting and Installation - Class II Install the meters in a suitable protective electrical control enclosure according to local wiring regulations. See specifications for maximum allowable temperature in enclosure. Allow adequate air circulation. Installing into front of panel 92mm +1mm -0mm Slide the meter, with gasket into the panel cutout Remove the two rear bracket... -
Page 8: Din Rail Mounting Option
DIN Rail Mounting option This series is ideal if you need high precision signal monitoring. Sometimes, there is not enough spare area available to have front panel indication, so in such cases, we offer a DIN rail mounting option, which allows the meter to be installed within a control panel. Detachable connectors add to the simplicity of installation, and of course the setup method is identical to the panel mounting version, so you don’t need to learn a new method. -

Other mounting options IP67 SPC4 The SPC4 splashproof cover gives IP67 / NEMA4-X protection for the front of your meter. Ideal for use in harsh wet environments. Available with optional security tag ports to allow you to fit your own crimped wire tamper-seals, to pre- vent or indicate unauthorised access (Similar to tags used on electricity... -
Page 10: Wiring Advice
Wiring Advice This meter uses detachable screw terminal connectors. Refer to the wiring diagram on the following page for the correct positioning of each wire. The conductors you use must be suitable for the meter’s temperature, current and voltage rating, which is broadly described as follows:- Cable Temperature Rating All cables must be rated for operation up to 90C continuous. -

Page 12: Installation Hints For Best Performance
Installation hints for best performance This section offers several suggestions which will help you get the best performance from your measurement system. Some sensors generate comparitively small signals which can easily be corrupted by the potentially high level of electrical noise which can be created by electrical machinery such as motors, welding systems, discharge lighting, AC power inverters and solenoids. -

Page 17: Display Calibration Modes
Meter Calibration Modes You can choose from two main calibration methods. 1. Direct Calibration - this is when you connect the meter to your system and make the meter read what you want it to, at 2 different points. This is the preferred calibration method, because it allows you to calibrate the system as a whole. -
Page 18: Direct Calibration
Direct Calibration - Full Scale Setting This is when you connect the meter to your system and make the meter read what you want it to, at 2 different points. This is the preferred calibration method, because it allows you to calibrate the system as a whole. How to do direct calibration:- If you have not done so before, please select Direct Calibration mode from the previous page. -

If you have not done so before, please select Theoretical Calibration mode from the Meter Calibration page AND choose whether your input is current or voltage.

Page 21: Theoretical Calibration
Theoretical Calibration - Low end calibration This is when you type in the sensor’s theoretical signal level at the top and bottom of its range and the value to display, for each signal level. If you have not done so before, please select Theoretical Calibration mode from the Meter Calibration page. -
Page 22: Sensor Drift Correction
Sensor Drift correction If your system is normally reading 0, for example as is typical with platform scales or a torque meter, you may find a small amount of sensor drift caused by changes in temperature, ageing etc. We can automatically correct for slow, long term drift, by comparing your signal to 0 every 30 seconds, and re-calibrating to remove any detected movement. -
Page 23: Logic Input Connections & Front Buttons
Logic input connections and front buttons The logic input provides a 5V DC signal. When you connect this to common, a current of 1mA will flow. Because this is a small signal, we recommend you use switches with gold plated contacts, or self cleaning contacts, for best long term reliability. The logic inputs are not galvanically isolated from the input signal. -
Page 24: Factory Defaults
Factory Defaults You can return the display to its factory default conditions whenever you wish. If you do so, you will permanently loose all your settings and will need to start from the beginning again. The calibration Audit Counter will NOT be reset, there is no way provided to reset this value, as it is intended as a secure record to indicate whether changes have been made to the display since it was last calibrated.. -
Page 25: Signal Filtering / Averaging
Signal Filtering / Averaging You can adjust the filtering time constant to reduce the effect of noise or instability on your input signal. A larger FIL value will give a more stable display, but the response to signal changes will be slower. -
Page 26: Last Digit Rounding
Last Digit rounding up by 1, 2, 5, 10, 20 or 50 You can adjust the way the display rounds up, which is useful if you want to display a very large number, but do not want jitter on the last digit. The display can be set to round up to the nearest 1 (no rounding) 2, 5, 10, 20 or 50 This feature is available in Easy and Advanced Modes Set1... -
Page 27: Menu Timeout Adjustment
Menu timeout adjustment The display has a default timeout of 60 seconds, to allow you sufficient time to refer to the manual between key operations. You can make this period shorter, if you wish, once you become more familiar with the setup method. -
Page 28: Bootup Routine Choices
Bootup routine choices When you switch on your meter, it can be set to power up with 3 possible summary mes- sage combinations. The choices are:- boot 0 Segment test, followed by a full summary of software revision, calibration audit number, model number, installed options. boot 1 Segment test followed by model number (Default) -
