a. Performance Check
(1) Set the rotary selector switch to the Hz position.
(2) Set calibrator output for 2 V at 10 Hz. TI will indicate within limits specified in
b below.
(3) Repeat technique of (2) above, using the remaining settings and indications
within limits specified in table 5, perform b below.

a. Performance Check
NOTE
The 2000 M and 200 M ranges have a fixed 10-count offset.
When the test leads are shorted together, the meter will
indicate 10. This residual value (10 M on the 2000 M and
1 M on the 200 M range) must be subtracted from readings
taken in these ranges.
.
(1) Set the rotary selector switch 200
(2) Set calibrator for a 19
(2-wire Comp: ON) output. The audible alert should sound.
(3) Set calibrator for a 190
nominal output.
