3.5.3.2 DCU Setup
The DCU has a directional coupler for each exciter to measure exciter power
external to the exciter. This power reading shows up on the Drive Meters screen in
Figure 3-6. This screen is used to calibrate the display readings. A digital power
meter is required to measure the DCU output. Then by pressing the CHANGE
button next to the reading to be calibrated, the + and - buttons can be used to change
the reading to that measured on the digital power meter. Once this is done press
SAVE to store the changes or CANCEL to ignore all changes made.
NOTE:
This procedure should only be done by qualified service personnel. For more
information on transmitter calibration refer to Section 5 Maintenance and
Alignments.
