(14) Repeat (7) and (8) above.
(15) Set calibrator for a 1 MΩ output then, using output adjustment controls, set calibrator
control display Reading equal to TI indication. If calibrator control display Error does not indicate
within 0.01%, perform b(1) through (9), (11), (12), (18) and (20) below.
(16) Press TI RANGE ↑ pushbutton to select 10 MΩ range.
(17) Set calibrator for a 0 Ω output.
(18) Repeat (7) and (8) above.
(19) Set calibrator for a 10 MΩ output then, using output adjustment controls, set calibrator
control display Reading equal to TI indication. If calibrator control display Error does not indicate
within 0.021%, perform b(1) through (9), (11), (12), (19) and (20) below.
b. Ohms Software Corrections
(1) Disconnect calibrator from TI.
(2) Slide rear panel CALIBRATION switch to ON and verify that AVG/(CAL) annunciator
is flashing.
(3) Release EXT GD IN pushbutton to out.
(4) Short TI VOLTS INPUT/OHMS SENSE HI and LO and AMPS INPUT/OHMS
SOURCE HI and LO in a four wire configuration using high quality, low-thermal, shorting bars.
(5) Allow sufficient thermal voltage settling time before proceeding.
(6) Press ZERO V DC/Ω pushbutton (ZERO annunciator off).
(7) Allow TI to take at least one measurement then press ZERO V DC/Ω pushbutton (ZERO
annunciator on). This operation stores new ZERO correction factors.
(8) Disconnect shorting bars from TI.
(9) Connect calibrator OUTPUT HI and LO to TI VOLTS INPUT/OHMS SENSE HI
and LO.
(10) Connect calibrator SENSE HI and LO to TI AMPS INPUT/OHMS SOURCE HI and
LO.
(11) Connect calibrator V-GUARD to TI GD.
(12) Press EXT GD IN pushbutton to in.
