4. With the field light energized measure and record 114 19.9 21.9
the voltage across the lamp socket terminals 112 19.5 21.5
using the digital voltmeter on the 200 VAC 110 19.0 21.0
scale.
5. Compare no-load battery voltage with collimator
lamp voltage. To provide required illumination,
lamp voltage must be no less than value listed in
the table. Too high a voltage will reduce lamp
life,
6. If necessary, shift secondary taps on 8TB1 to
provide required collimator lamp voltage. Care- 29 ㆍ | 30 | τι
