4.3 Calibration Procedures (Refer to Figure 4-1)
Connect the calibration equipment according to Figure 4-1 or 4-2. The thermocouple wire (J, K, T, E) must be of the same calibration as the transmitter being calibrated. Make sure that the wiring polarities are correct. (Note that the RED thermocouple wire is NEGATIVE.)
To check or adjust the calibration:
1.Locate the Z (zero) and S (span) potentiometers.
2.Select, from Table 4-1, the correct mV values for the Z (zero) and S (span) adjustments that correspond to the Model Number. For example, for Model TX91-J2, the Z input is -0.885
19mV, and the S input is 4.906 mV.
