a. Performance Check
(1) Press FUNCTION ~ V (ac volts) and 20 V RANGE pushbuttons.
(2) Connect a short between the VΩ and COM jacks. If TI does not indicate 0.00
V ac, perform b(1) below.
(3) Remove the short and connect VΩ and COM jacks to calibrator.
(4) Set calibrator output to 19 V and frequency to 200 Hz. If TI does not indicate
between 18.91 and 19.09 V, perform b(2) below.
(5) Set calibrator frequency to 20 kHz. If TI does not indicate between 18.91 and
19.09 V, perform b(3) below.
(6) Set calibrator frequency to 100 kHz. If TI does not indicate between 18.61 and
19.39 V, perform b(4) below.
(7) Set calibrator output to 1.9 V and frequency to 20 kHz.
(8) Press 2V RANGE pushbutton. If TI does not indicate between 1.891 and 1.909
V ac, perform b(5) below.
(9) Repeat technique of (4) through (8) above, using settings and indications
