impedance of 10 MΩ 10%.
15. Dc Voltage
a. Performance Check
(1) Connect TI cable to the handheld meter VΩ
and COM observing correct polarity.
(2) Set handheld meter to 3 V range.
(3) Connect the TI ground clip lead to calibrator OUTPUT LO. Hold the probe by
the black handle and connect the probe tip to calibrator OUTPUT HI.
(4) Set calibrator to 1000 V.
(5) Push calibrator OPR/STBY button to OPR, handheld multimeter should
indicate between .990 and 1.010 V. No calibration adjustments can be made on the probe.
(6) Set calibrator to STBY.
b. Adjustments. No adjustments can be made.
