9. AC Voltage
a. Performance Check
(1) Press DC/AC pushbutton to AC (in) and press the 200 mV range pushbutton.
(2) Set TI range and calibrator for voltages and frequencies listed in table 4. TI will
indicate within the specified limits; if not, perform b below.
b. Adjustments. Set TI range to 200 mV and calibrator for a 190 mV, 45 Hz output.
Adjust AC CAL R4 (fig. 1) for a TI indication of 190.0 (R).

10. DC Current
a. Performance Check
(1) Connect calibrator OUTPUT terminals to TI mA and COMMON terminals, set
TI range to 2 mA, and set DC/AC pushbutton to DC (out).
(2) Set TI range and calibrator output as specified in table 5. TI will indicate within
the specified limits.
b. Adjustments. No adjustments can be made.
