NOTE
Ensure probe is shielded from local fields for (2) below.
(2) Replace probe tip with 50 : termination.
(3) Adjust ZERO control for zero indication on TI meter.
(4) Connect multimeter (dc mode) to TI RECORDER OUTPUT (rear panel). If
multimeter does not indicate between -0.01 and +0.01 V dc, perform b (1) below.
(5) Replace 50 : termination with probe tip.
(6) Press 1000 mV FULL SCALE pushbutton.
(7) Connect probe to calibrator OUTPUT V:A HI and LO terminals.
(8) Adjust calibrator controls for 10 kHz and a full-scale indication on TI. If
multimeter does not indicate between 9.9 and 10.1 V dc, perform b (2) below.
(9) Set calibrator to standby operation.
(10) Disconnect calibrator and multimeter from TI.
(11) Connect ac divider input to calibrator OUTPUT VŸA HI and LO terminals.
(12) Set TI pushbuttons as listed in the first row of table 4 and adjust ZERO control
for zero indication on TI meter.
(13) Connect TI probe to ac divider output.
(14) Adjust calibrator controls for 10 kHz and a full-scale indication on TI. If
calibrator does not indicate within limits specified, perform corresponding TI adjustments.
(15) Disconnect TI probe from ac divider.
(16) Repeat technique of (12) through (15) above for remaining settings in table 4.
