18. Meter Accuracy
a. Performance Check
(1) Adjust dc power supply for an indication of 8 on TI KILOVOLTS meter. If dc
power supply does not indicate between 7700 and 8300 V, perform b below.
(2) Reduce dc power supply output to minimum.
b. Adjustments
(1) Adjust dc power supply for a 10,000 V output.
(2) Adjust R4 (fig. 6) for TI indication of 10 (R).
