(19) Set calibrator for a .3 V output. Adjust A/D ANALOG R527 REM (fig. 1) for TI
indication between .2999 8 and .3000 2 VD (R).
(20) Press S1 (fig 2) to return to normal mode.
(21) Press S1 (fig. 2) to select cal digit mode.
(22) Set calibrator for a 120 V output. Adjust I/O SWITCH R109 1000 V (fig. 1) for
TI indication between 119.999 4 and 120.000 6 VD (R).
(23) Press S1 (fig. 2) to return to normal mode.

a. Performance Check
(1) Press Ω 4-WIRE pushbutton and RANGE ∆ or ∇ pushbutton to select 10Ω
range.
(2) Press READING RATE ∆ or ∇ pushbutton to select 1/SEC rate.
(3) Connect calibrator OUTPUT HI and LO to TI V/Ω INPUT HI and LO.
(4) Connect calibrator SENSE HI and LO to TI Ω SOURCE HI and LO.
(5) Set calibrator for a 0Ω output, EX SNS on and 2 wire Comp off. If TI does
not indicate .0000Ω 12 digits, perform b(1) through (4) below.
(6) Press READING RATE ∆ or ∇ pushbutton to select 2/SEC rate.
(7) Set calibrator for a 10Ω output then, using calibrator output adjustment
controls, set calibrator control display Reading equal to TI indication. Calibrator
control display Error will indicate within 0.026 %.
(8) Repeat technique of (1) and (7) above for TI and calibrator settings listed in
perform adjustments listed in table 4.

(9) Set calibrator to STANDBY and disconnect from TI. Connect resistance
standard set for 10 MΩ to TI VΩ /INPUT HI and LO.
(10) Press nS pushbutton. TI will indicate between 99.89 and 100.11 nS.
