4 .4 .6 Set the Calibrator for the first value listed in the Applied column of Table 8 and set the OPR/STBY switch to
OPR.
4 .4 .7 Edit the Calibrator controls until the AC Measurement Standard indicates the value listed in the Applied
column of Table 8.
4 .4 .8 The TI display must indicate within the corresponding values listed in the Limits column of Table 8.
4 .4 .9 Set the Calibrator OPR/STBY switch to STBY.
4 .4 .10 Repeat steps 4 .4 .4 through 4 .4 .9 for each remaining range and applied value listed in Table 8.
NOTE
Grounding/Shielding variations may be required to obtain a stable and accurate
TI indication
. The TI LFILTER may be used in Table 8 for frequencies up
through 50 kHz . Disengage TI LFILTER for frequencies above 50 kHz . To
engage TI LFILTER press the TI keys in the following sequence:
