(5) Press polarity pushbutton to + and adjust VOLTS counter to 0.100. Multimeter
will indicate between +0.0944 and +0.1051 V dc.
(6) Repeat technique of (5) above for VOLTS counter settings listed in table 4.
Multimeter will indicate within limits specified.

(7) Press polarity + (positive). Repeat technique of (1) and (2) above. If multimeter
does not indicate between +9.985 and +10.015 V dc, perform b (3) below.
(8) Press polarity - (negative) pushbutton. If multimeter does not indicate between -
9.985 and -10.015 V dc, perform b (4) below.
(9) Press polarity + (positive) pushbutton. Adjust COARSE and FINE controls
until VOLTS counter indicates 5.000. If multimeter does not indicate between +4.997 and
+5.003 V dc, perform b (5) below.
b. Adjustments
NOTE
Interaction exists between R573 and R575 (fig. 2).
If
adjustments were made, repeat a (1) through (5) above for best
compromise.
(1) Adjust R573 (fig. 2) for a 10 V dc indication on multimeter (R). Adjust for best
compromise between + and polarity.
(2) Adjust R575 (fig. 2) for a 1 V dc indication on multimeter (R). Adjust for best
compromise between + and - polarity.
(3) Adjust R686 (fig. 2) for a +10 V dc indication on multimeter (R).
(4) Adjust R727 (fig. 2) for a 10 V dc indication on multimeter (R).
(5) Adjust R696 (fig. 2) for a +5 V dc indication on multimeter (R).
