(20) Set calibrator for 50 kHz and 160.0 V output. Adjust C14 for a TI indication of 160.000 V (R).
(21) Set calibrator for 500 Hz and 500.0 V output. Adjust R64 for a TI indication of 500.00 V (R).
(22) Set calibrator for 50 kHz and 500.0 V output. Adjust C4 for a TI indication of 500.00 V (R).
11. Resistance (Option 02)
a. Performance Check
(1) Connect calibrator OUTPUT HI and LO to TI INPUT VOLTS/Ω SENSE HI
and LO.
(2) Connect calibrator SENSE HI and LO to TI INPUT AMPS/Ω SOURCE HI
and LO.
(3) Press TI FUNCTION OHMS pushbutton.
(4) Press RANGE UP or DOWN pushbutton to select 10 Ω range.
(5) Set calibrator for a 0 Ω output, EX SNS on.
(6) Press TI 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).
(8) Set calibrator for a 10 Ω output then, using output adjustment controls, set
calibrator control display Reading equal to TI indication. If calibrator control display
Error does not indicate within 0.03%, perform b (1) below.
