ADDENDUM
On specific model of the SCM2500XRD, the analog output (4-20mA) representing the Offset
value is provided at terminals 11 and 12; see figure below. Terminal 11 is labeled Offset Value
(AO+) and terminal 12 is labeled Offset Value (AO-). The scaling for the Offset value analog
output is from -1000 to +1000 streaming current value. The two analog outputs are provided to
allow the customer to monitor the SCV Signal and Offset value remotely. The explanation of
the Offset mode and Offset value are described in Section 3.2.2 SCM2500XRD Setup Menu
(1).
WARNING TURN POWER OFF BEFORE MAKING ANY WIRE CONNECTIONS
TO AVOID DAMAGING THE ELECTRONIC CIRCUIT.
