10.3Calibrating Analog Output Signal

Background

Procedure

You can calibrate the transmitter’s analog output circuit at its 0 and 100% levels by using the transmitter in its constant-current source mode (or output mode). It is not necessary to remove the transmitter from service for this procedure.

Depending if you are using the SCT 3000 or the SFC to perform calibration, refer to the appropriate sections below for the procedure. The procedure shows you how to calibrate the output signal for a transmitter in the analog mode. Note that the procedure is similar for a transmitter in the DE mode, but the SCT (or SFC) must be used to read the output in percent in place of the milliammeter or voltmeter readings.

See Figure 28 for a sample test equipment setup. Using the SCT, select the topic:

“Calibrating Output at 0 and 100% for an SMV 3000 Transmitter” and Click on “PV4 Output Calibration Form (FLOW OutCal)” to view the procedure.

Using the SFC:

Follow the procedure for “Calibrating the Output Signal for Transmitter in Analog Mode” in Section 7 of the SFC Operating Guide.
