Calibrating a Transmitter

Use the measurement (upper display) and source (lower display) modes to calibrate a transmitter. The following example shows how to calibrate a temperature transmitter.

Connect the calibrator to the instrument under test as shown in Figure 15. Proceed as follows to calibrate a transmitter:

1.Press Kfor current measurement with loop power.

2.Press T(lower display). If desired, continue pressing this key to select the desired thermocouple type.

3.If necessary, press Mfor SOURCE mode.

4.Set your zero and span parameters by pressing X and Wkeys. Enter these parameters by pressing and holding Jand G. For more information on setting parameters, see “Setting 0 % and 100 %” earlier in this manual.

5.Perform test checks at 0-25-50-75-100 % points by pressing Hor I. Adjust the transmitter as necessary.
