a. Test Set.
Function
Control, indicator, or connector
IND TEST Switch (7-position rotary
switch, selects UUT)
Connects test set circuits for monitoring of outputs from a
RCVR-V/L
VOR/LOC receiver.
Connects test set circuits for monitoring of outputs from a
RCVR-GS
glideslope receiver.
Provides for test of the TO/FM meter movement of the
VOR/LOC-TO/FM
ID-1347C/ARN-82B.
COR/LOC-DEV
Provides for test of the R-L deviation meter movement of
the ID-1347C/ARN-82B.
Provides for test of the LOC flag meter movement of the
VOR/LOC-FLAG
ID-1347C/ARN-82B.
provides for test of the GS flag meter movement of the
GS-FLAG
ID-1347C/ARN-82B.
Provides for test of the glideslope deviation meter movement
GS-DEV
of the ID-1347C/ARN-82B.
Provides observation of the direction of the simulated
COMPASS SIMULATOR indicator
magnetic heading signal.
Provides manual control of the direction of the simulated
Compass simulator control
magnetic heading signal.
Selects internal circuit of test set to allow testing of either
MODE
radio operating at 30 or 400 Hz.
When illuminated, it indicates the presence of the 27.5 volts
VOR/LOC 28VDC lamp
dc used by the receiver.
When illuminated, it Indicates the presence of the 115
VOR/WC 115VAC lamp
volts. 400 Hz used by the receiver.
When illuminated, it indicates the presence of the 27.5 volts
GS 28VDC lamp
dc used by a glideslope receiver.
Selects simulated bearing signals from 0 to 360 degrees in
BEARING selector switch (12-
30-degree increments. These signals are used to accurately
position rotary)
calibrate and test the receiver, and to check the accuracy of
the OBS indicator.
Selects either the precision BEARING selector or the OBS
BRG-OBS switch (2-position rotary)
indicator to supply course selector information to the
receiver.
Places the precision BEARING selector in the test set circuit.
BRG (bearing)
Places the OBS indicator in the test set circuit.
OBS /omnibearing selector)
Selects marker beacon or VOR/LOC audio output during
AUDIO (switch)
meter tests.
