(b) RANGE 1 key to on.
(c) HIGH RESOLN key to on.
(d) TRIGGER INTERNAL key to on.
(e) MATH OFF key to on.
(f) AUTO CAL key to on.
(g) GUARD pushbutton pressed to on.
(4) Set calibrator for a 1 kΩ output, EX SNS on, and 2 wire Comp off then, using
output adjustment controls, set calibrator control display Reading equal to TI
indication. If calibrator control display Error indication is not within 0.0046%, perform
b below.
(5) Press RANGE 100 key to on.
(6) Set calibrator for a 100 kΩ output then, using output adjustment controls, set
calibrator control display Reading equal to TI indication. If calibrator control display
Error indication is not within 0.0047%, perform b below.
