(2) Short TI leads. If TI display does not indicate between -00.5 and +00.5 perform
b (1) below.
(3) Connect TI V-Ω input to calibrator OUTPUT HI and TI COM input to
calibrator OUTPUT LO. Set calibrator for an output amplitude of 190 mV at an
output frequency of 1 kHz. If TI does not indicate within limits specified in first row of

If TI does not indicate within limits specified perform b (3) below.
b. Adjustments.
(1) Short TI leads and adjust R206 (fig. 1) for a TI indication of 0.00.
(2) Set calibrator for an output amplitude of 190.0 mV at a frequency of 1 kHz and
adjust R203 (fig. 1) for a TI indication of 190.0 mV (R).
(3) Set TI to 2 V range and set calibrator for an output amplitude of 1.900 V at a
frequency of 5 kHz and adjust C101 (fig. 1) for a TI indication of 1.900 V (R).
10. Dc Current
a. Performance Check
(1) Position TI controls as listed in (a) through (c) below:
(a) AC DC pushbutton to DC (out).
(b) mA pushbutton to in position.
(c) 200 mV, 200 A, 200 Ω pushbutton to in position.
(2) Connect TI mA input to calibrator OUTPUT HI and TI COM input to calibrator
OUTPUT LO.
