8. Electro-Optical Gain Accuracy
a. Performance Check
NOTE
Scribe lines are not used on the transfer NVD detector
standards (TI), but the TI must be rotated in the alignment
collar to peak the voltage output.
(1) Install TI into auxiliary source collimator port, connect BNC cable to TI BNC
jack, and ensure that TI is firmly seated into the alignment collar.
(2) Turn TI power ON/OFF switch to ON and allow TI to warm-up for 3 minutes.
(3) Set auxiliary source II, III, OFF switch to OFF.
(4) Zero multimeter indication.
(5) Verify that TI noise level does not exceed 0.02 mV. (No adjustments can be
made). Return TI to primary for maintenance/repair.
(6) Set auxiliary source II, III, OFF switch to II, and allow 2 minutes for settling time.
(7) TI will indicate between 421 and 495 mV.
(8) Deenergize and replace TI with secondary reference NVD detector standard to
verify correct operation of auxiliary source. Repeat subparagraphs 8 a (1) through (4), (5)
(except for 10 minute warm-up), and (7).
CAUTION
Ensure proper alignment of scribe lines on reference NVD.
b Adjustments. No adjustments can be made.
If out of tolerance, return TI to
primary for repair/recertification.
9. Final Procedure
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA label/form in accordance with TB 750-25.
