Adjustment Procedure—DM 5010
d. ADJUST—the 200 V H.F. Comp. (C1607) for a
DM 5010 display reading of 190.00, ± 0.02 V, using an insu­
lated adjustment tool. Refer to Fig. 10-1. After adjustment,
recheck the DM5010 display reading and readjust, if
necessary.
NOTE
If C1607 approaches the end of its adjustment range,
turn off the power module, and remove the RMS

the same direction required for additional range by
C1607. Reinstall the board, turn on the power module,
and readjust C1607.
e. Set the ac calibrator output to 1.9000 V at 20 kHz,
±200 Hz.
f. Set the DM 5010 range to the 2 V range.
g. ADJUST —the 2 V/200 mV H.F. Comp. (C1503) for a
display reading of 1.9000, ±0.0002 V.
h. Set the DM 5010 to the 20 V range.
i. Set the ac calibrator output to 19.000 V at 20 kHz,
±200 Hz.
j. ADJUST— the 20 V H.F. Comp. (C1403) for a display
reading of 19.0000, ±0.005 V.
k. Set the DM 5010 to the 200 V range and repeat parts
b through j to verify that the adjustments have not changed.
l. Set the ac calibrator output to a minimum level and
