7. Equipment Setup
WARNING
HIGH VOLTAGE is used or exposed during the performance of
this calibration.
DEATH ON CONTACT may result if
personnel fail to observe safety precautions. REDUCE
OUTPUT(S) to minimum after each step within the
performance check where applicable.
a. Measurements can be adversely affected by temperature.
The optimum
temperature for this calibration is 23 C (73.4 F).
b. Exercise TI dials before beginning calibration.
c. Record measurement results for test report if required.
See paragraph 9 for
explanation.
8. Capacitance Accuracy
a. Performance Check
(1) Ensure that the impedance measuring system is set to measure series
capacitance at a test voltage of 1 V rms and a test frequency of 1 kHz.
(2) Perform short and open compensation on impedance measuring system (fig. 1,
connections A and B).
