b. Adjustments
(1) Adjust AC ZERO ADJ R203 (fig. 1) for a TI indication of 0.00 V ac (R).
(2) Adjust AC GAIN ADJ R123 (fig. 1) for a TI indication of 19.00 V ac (R).
(3) Adjust 20 V HI FREQ ADJ R102 (fig. 1) for a TI indication of 19.00 V ac (R).
(4) Adjust 20 VAC ADJ C109 (fig. 1) for a TI indication of 19.00 V ac (R).
(5) Adjust 2 V HI FREQ ADJ R110 (fig. 1) for a TI indication of 1.900 V ac (R).
11. Resistance
a. Performance Check
(1) Press FUNCTION kΩ and 20Ω RANGE pushbuttons.
(2) Short VΩ and COM jacks. If TI does not indicate 0.00Ω , perform b(1) below,
then remove short.
(3) Connect calibrator output terminals to TI INPUT VΩ and COM terminals.
(4) Press 2 0 kΩ RANGE pushbutton and set calibrator to nominal 19 kΩ. Adjust the
calibrator output adjustment control knob for a calibrator control display reading equal to the TI
indication. The calibrator control display ERROR indication will be within .3000%; if not, perform
b(2) below.
(5) Set TI range and calibrator to the nominal resistance outputs listed in table 6.
At each resistance input, adjust the calibrator output adjustment control knob for a
calibrator control display reading equal to the TI indication. The calibrator control
display ERROR indication will be within the specified limits of table 6.
