indicate 0, adjust meter mechanical zero for 0 indication.
a. Performance Check
(1) Set SELECTOR switch to +.
(2) Connect DC probe and COMMON lead together and adjust ZERO ADJ for 0
meter indication.
(3) Connect DC probe and COMMON lead to calibrator OUTPUT HI and LO.
(4) Adjust calibrator for a full scale indication on TI.
If calibrator does not
indicate between 0.970 and 1.030 V, perform b below.
(5) Repeat technique of (4) above using settings and indications listed in table 3.
