TR-2100 User Manual
shunt error. In this case, the test current can be found by dividing the shunt resistor value
(found in the CT section of the User specification Sheet) into the equivalent test voltage:
Test voltage = 1.000V
Shunt = 130 ohms
Test current = 7.6923mA
Therefore, a test current of 8.000mA would be acceptable
The TR-2100 can be calibrated using a DC or AC signal. The input channels of a TR-2100
are defined as either AC (transformer) or DC (transducer). This indicates the type of input
signal and NOT the type of coupling. The TR-2100 uses this information to determine if the
FSD is an RMS value, and if the inputs must be scaled to accommodate the peak value.

The value that is fed into the recorder should be at least half the Full Scale Deflection.
150.00 V ac is a good value for voltage inputs, and 1.0000 V ac is good for current inputs.
For each channel, type in the FSD and the value being fed in to the input card. If all channels
are setup with the same FSD and expected value, then the Mirror First Selection check box
can be set. This will copy the first value and first FSD fields into all the boxes.
