N.B The voltage between either of the power supply connections and the load cell chassis should not exceed 50 V. Any leakage will be greater than 10 M ohms. Mantracourt Electronics Limited – ICA User Manual... -
Page 5: Ica1H & Ica2H Connections
ICA1H & ICA2H Connections The power supply for the ICA1H is nominally 24 V dc (between 13 and 28 V) and ICA2H is nominally 12 V dc (between 8.5 and 28 V).The power supply is commoned with the output at the ‘Com’ connection. -

This will offs... - Page 13 If the gain is to be decreased for a higher mV/V input then the two surface mount resistors must be removed. It is then possible to use just the top pair of formulas as with the other models. Example 1: ICA1H, no offset, 0.5 mV/V required sensitivity. Gain constant ��������...

Ensure you have the calibration set-up correctly installed i.e. mV source and output as required. d) Ensure the temperature and other environmental parameters are within specification and where necessary taken into account when calibrating should such parameters have an effect on the calibration. Mantracourt Electronics Limited – ICA User Manual... - Page 18 If the potentiometer does not alter the output the unit must be repaired – remove from service. c) It is always wise to check a known good ICA against the problem installation before rejecting the suspect ICA.
