|
|
|
|
1. | RECORDER OUTPUT selector plug | Provides selectable output of 10 mV, 100 mV, 1 V or 5 V for a voltage recorder. | ||
2. | DIGITAL READOUT (R100) | Calibration of digital readout. | ||
3. | AMPLIFIER U8 ZERO (R29) | Initial factory zeroing of amplifier U8. | ||

|
|
|
|
4. | RESPONSE TIME (R30) | Adjustment of electronic response time. | ||
|
|
|
|
|
5. | FULLSCALE OUTPUT (R88) | Setting fullscale for 1 V, 0.1 V and 10 mV outputs. | ||
|
|
|
|
|
6. | DETECTOR COARSE ZERO (R9) | Coarse adjustment of detector zero by shifting the position of the detector within the mag- | ||
|
|
| netic field. It is adjusted during factory checkout, and does not require readjustment except | |
|
|
| if detector is replaced. | |
7. | CURRENT OUTPUT ZERO (R1) | Located on Current Output Board, adjustment for | ||
|
