Additional Test: Diode Test
1. Select the TI DIODE TEST, function
respectively connected to the Calibrator HI and LO terminals, LO is connected to Calibrator
GUARD.
2. Set calibrator for 0.6 V output (1 V x 0.6) and verify that the TI indication is within 0.593
to 0.607 and that the TI "beeped' briefly.
3. Set Calibrator for minimum output, disconnect TI from Calibraor and with TI terminals
"open circuit", verify that the TI indicates overload: OL
4. Short TI input terminals and verify the TI emits a continuous tone. (end of test)
Affix a special calibration label stating:
1. The TI DC and AC current functions have not been calibrated.
2. The 32 and 320 V ranges (both DC and AC function) have been calibrated only at approx
1/3 of full range.
3. The TI 1000 V dc and 750 V ac ranges have been calibrated only at 100 V level.
