4.8 SETTING OF MONITOR ALARM LIMITS
4.8.1 Monitor 1
4.8.1.1 Azimuth
a) Choose azimuth value 'M1 Azimuth'.
(equal to azimuth value of monitor dipole 1).
b) Upper limit: Add 1.0° to 'M1 Azimuth' reading and key in this value.
c) Lower limit: Subtract 1.0° from 'M1 Azimuth' reading and key in
this value.
NOTE: Range of values: 0...359.9;
If during flight check azimuth of transmitters has to be changed,
these azimuth alarm limits have to be readjusted.
4.8.1.2 RF-Level
a) Upper limit, e.g. 123 %.
b) Lower limit, e.g. 71 %.
NOTE: Range of values: Upper Limit 100...150, Lower Limit 50...100.
4.8.1.3 30 Hz AM Signal
a) Upper limit, e.g. 34.5 %.
b) Lower limit, e.g. 25.5 %.
NOTE: Range of values: 0...39.9.
4.8.1.4 9960 Hz Signal
a) Upper limit, e.g. 34.5 %.
b) Lower limit, e.g. 25.5 %.
NOTE: Range of values: 0...39.9.
4.8.1.5 30 Hz FM Signal
a) Upper limit, e.g. 18.4.
b) Lower limit, e.g. 13.6.
NOTE: Range of values: 0...39.9.
