Page 5: General Description
General Description This meter has been designed to be simple to configure. It is easy to use because no menu is used. Look at the front panel below... to adjust ZERO you press the ZERO button, to adjust Span you press the SPAN button, to adjust Analogue Output you press the OUTPUT button, to adjust Alarms you press the ALARM button. -
Page 6: Getting Started
Getting Started First, please check that the display will suit all the requirements of your application. Page 4 has some important warnings - please check that all warnings are covered. If you have analogue output or alarm relay options, you may need to configure their boards before installing the meter in a panel. - Page 7 Connections These connectors are only used when options are fitted Analogue Serial ALARM RELAY OUTPUTS Output Output 14 15 16 17 18 19 20 21 22 23 24 25 26 27 REAR VIEW 1 2 3 4 5 6 7 8 9 10 11 12 13 Mains Power model DC Power model INPUT...
- Page 8 Calibration Set switch 1, near the input connector ON and lockout switch OFF 1) How to set SPAN and DECIMAL POINT Press the SPAN button for 3 seconds. You’ll see ‘dC V’ or ‘dC A’ if the meter is set for DC Voltage or DC current. Use the up or down arrow to change, if needed and then press OK.

Page 9: Calibration Examples
Calibration Examples 4 to 20mA = 0 to 300m per day flow rate. You want to display total m passed a. Set ‘Int d’ because your flowrate is described in m per day b. Set InHi = 20.000mA c. Set rd Hi to 300 (after 24 hrs at 20mA, the display will reach 300) d. - Page 10 Filter and Last Digit Roundup Press the OK button 5 times to access the filter time constant, which is expressed in seconds. You can use the filter to improve your display stability with fluctuating input signals. Use the UP and DOWN buttons to select a time constant in the range 0 to 5 seconds.
- Page 11 Features Calibration Counter / Tamper detector An internal totaliser counts each calibration. The ‘CAL XX’ value appears for a second or two after you switch the meter on. The number starts at 00 and can go up to FF (255 counts). It doesn’t count changes of setpoints, or changes of filter value or count-by value .
- Page 12 How to install option boards If you want to open the meter to install or modify option boards, follow these steps... 1) Switch off power to the meter and unplug all connectors. 2) Unclip the front bezel. This is easier if you squeeze the top and bottom of the case, near the front.
- Page 13 Alarm Board Configuration & Adjustment For failsafe operation (where contacts open on alarm or when power is lost to the meter) set the jumpers for OPEN CONTACTS and DE-ENERGISE on alarm. To access to the alarm board, first remove power from meter, including any power which might be on the alarm output circuitry.

Page 14: Alarm Settings
Alarm settings If you press the ALARMS button momentarily, you can view each of the 4 alarm settings (each press will illuminate in turn AL1, AL2, AL3 and AL4 LEDs). Alarm settings are not locked out by the lockout switch. Max. - Page 15 In-Flight Compensation You can configure the meter to have in-flight compensation, which can improve alarm accuracy in some applications. Here’s how it works..Imagine you have a storage container and you want to empty a certain amount of material from that container into a bin. When the bin reaches the desired weight, the meter will switch off the shutoff valve.

Page 16: Analogue Output Configuration
Analogue Output Configuration We always set the meters to suit any requests on your order, so you should not need to adjust the analogue board. If you didn’t specify ranges, but ordered option ‘ANI’, the meter will be set for 4-20mA output. If you ordered ‘ANV’ it will be set for 0-10V. - Page 17 How to adjust your Analogue Output The lockout switch should be set ‘OFF’ to change the analogue output calibration. You can set the analogue output range to suit your display range. The analogue output can be directly proportional or inversely proportional to the display range, for example you can have 4-20mA output for display 0 to100 or for display 100 to 0.
- Page 18 Serial Communications Output Option You can have either an RS232 or an RS422 ASCII output at 1200 baud representing the meter’s displayed value. You can have a continuous transmission of readings, or a single transmission on demand. RS232 O/P on terminal 16 (data+) and terminal 18(common) RS422 O/P on terminals 16 &...
- Page 19 8 Programme Memory Option With the MEM-08 option, you can store up to 8 sets of configuration and calibration data. This is useful if you want to connect a number of different sensors, each with different calibration, to the meter, selected by rotary switch. Each memory location can have its own input/display calibration, alarm settings, and analogue O/P calibration.
