NOTE
The CAL MODE of operation prevents the TI from over-
ranging during adjustments at the range upper limit. Ignore
the CAL digit when performing remaining checks and
adjustments.
(7) Lift CAL switch cover (tab) and slide CAL switch to CAL MODE (down).
PEAK or CAL light will be flashing.
(8) Set calibrator for a -20.0 V dc output. Record absolute value of TI indication.
(9) Set calibrator for a +20.0 V dc output. Record absolute value of TI indication.
(10) If difference between absolute value of TI indications recorded in (8) and (9)
above is not less than 10 digits, perform b (8) through (11) below.
(11) Set calibrator OPR/STBY to STBY.
(12) Press FUNCTION VAC pushbutton and select the 1V manual range.
(13) Set calibrator output to 2.5 mV at 500 Hz. If TI does not indicate between
0.00211 and 0.00288 V, perform b (12) below.
(14) Repeat technique of (12) and (13) above using settings and indications listed in
table 4. If TI
does not
indicate within
limits specified, perform corresponding adjustments.
(15) Lift CAL switch (tab) and slide CAL switch out of CAL MODE (up).
