POSITION FUNCTION
PROBE PK AC Probe will measure peak alternating current voltages 0 to 30 Vac
PROBE +VDC Probe will measure direct current voltages 0 to +3 Vdc
PROBE +VDC Probe will measure direct current voltages 0 to +30 Vdc
PROBE -VDC Probe will measure direct current voltages 0 to -30 Vdc
+/-22VDC Normally measures the +22 Vdc power supply voltages 0 to +30
Vdc. When S1 on the transmitter interface is pressed and held
down measures the -22 Vdc power supply voltage 0 to -30 Vdc
+/-8VDC Normally measures the +8 Vdc power supply voltages 0 to +10
Vdc. When S1 on the transmitter interface is pressed and held
down measures the -8 Vdc power supply voltage 0 to -10 Vdc
B+/B-VDC Normally measures the B+ Vdc power supply voltages 0 to +30
Vdc. When S1 on the transmitter interface is pressed and held
down measures the B- Vdc power supply voltage 0 to -30 Vdc
+12VDC Measures the +12 Vdc power supply voltage 0 to +30 Vdc
A/D IN +VDC Measures the audio +DC input to the A/D converter 0 to +10 Vdc
A/D OUT +VDC Measures the reconstructed audio +DC output of the A/D
converter 0 to +10 Vdc
B- DRIVE -VDC Measures the B- drive signal out of the analog input 0 to -10 Vdc
