D. Transducer Calibration if not applying physical variable
Use this procedure if you can’t easily generate the required physical variable changes in order to calibrate the
transducer.
1. Calculate the de-normalized calibration factor, VY.
a) Note the factory calibration constant (generally listed as “Output” in the transducer
specifications), expressed in the form of voltage/physical variable (V/P),
b) Multiply V/P by the reference voltage (RV) of the DA100C (2 V factory preset).
c) Multiply the result [(V/P) * RV] by the Gain switch setting value on the DA100C.
2. Plug the transducer into the DA100C.
3. Press Cal 1 …this will generate VB in the Input Voltage box
4. Enter the ambient physical value in the Cal 1 Map/Scale window
5. Enter Cal 2 Input Voltage as V
Y
+V
B
6. Enter the ambient + delta physical value in the Cal 2 Map/Scale window
