1.49 Peformance Monitor
The performance monitor (PM-30 for FR-1710/1725, PM-50 for 1760DS) provides an effec-
tive means of general performance check of a radar installation. It works like a transponder.
Installed in the proximity of the radar antenna, it is triggered by part of the transmitted micro-
wave energy and sends back a coded signal to the antenna for display on the radar screen.
Overall performance can be checked from the range, size and number of arcs displayed on
the radar screen. For further details see the operator’s manual of the performance monitor.
To turn on the performance monitor:
1. Press the [MENU] key.
2. Press the [0] key twice to display the OTHER menu.
3. Press the [5] key twice to open the DISPLAY menu.
