5-23-1. BATTERY ALARM SET Adjustment
Notes :
• This adjustment is only for the camera incorporating the
standalone unit BKP-5910/5910P.
• Adjustment for
1
RV4 is very critical. Do not turn it as
far as the circuit normally activates.
Equipment
:
Digital voltmeter
Oscilloscope
DC variable power supply
Preparation :
• Supply about +13 Vdc from the DC variable power
supply via the DC IN connector of the BKP-5910/5910P.
Adjustment Point :
1
RV4/AU-211 (D-4)
Adjustment Procedures:
1.
Turn
1
RV4 fully clockwise.
2.
Measure voltage at TP84 (GND:GND A)/extension
board (extending AU-211).
3.
Adjust the voltage at TP84 for +11.20
±
0.05 V.
4.
Slowly turn
1
RV4 counterclockwise observing the
waveform at TP42/extension board (extending AU-
211) on the oscilloscope.
5.
Adjust
1
RV4 so that an 1.0-Hz, 8.0-Vp-p rectangler
wave just appears.
