4 OPERATION

4.3.7 Filter Function

The damping set within this sub-menu prevents display and output current fluctuations.
There are 10 steps available. However, the first step ("FILTER 0") has no damping function.

4.4.1 Offset Compensation
Within this mode, the user has the possibility of correcting the basic setting of 4 mA. An
ammeter is required. The transmitter generates 4 mA, if the ENTER key is pressed when
"OFFSET" is displayed. If the displayed value is incorrect, it can be corrected by enter the
measured value.

Display of non-compensated conductivity.
Enter the conductivity to be simulated. The outputs will react
according to this input.
Return to the operation mode and store the new parameters set
for OFFSET and SPAN. If one of the two values is inappropriate,
the device will revert to "OFFSET" position, and new values must
be entered.
