Calibration equipment connections are as shown in Figure 6-4.

A. NARROW MILLIVOLT CALIBRATION

1. From the MXC, execute the FIND XMTR program then select CAL/TEST (F2) from the display

menu.

2. Step through the MXC screens using the PREV and NEXT buttons to select NARROW

MILLIVOLT calibration. Press SELECT (F4).

7. Press CONT (F4) to calibrate.

Press ABRT (F3) to quit without changing calibration.

8. Narrow Millivolt calibration is completed.

If no other calibrations are required, disconnect test equipment, reconnect all wires, and install

enclosure cap.

If Wide Calibration is required, retain test set-up and proceed to paragraph B.

B. WIDE MILLIVOLT CALIBRATION

1. From the MXC, execute the FIND XMTR program then select CAL/TEST (F2) from the display
