7. Equipment Setup
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 checks where applicable.
a. Connect calibrator to TI
and COM input.
b. Set function switch to DC V 200m.
8. DC Voltage
a. Performance Check
(1) Set calibrator for an output of 200 mV.
(2) If TI does not indicate within limits specified in first row of table 3, perform b
below.
(3) Repeat technique of (1) and (2) above, using the remaining settings and
perform b below.
