(21) Set calibrator for a 1000 V dc output. Allow TI to take at least one measurement, then
press STORE (1000.000) (CAL COR).
(22) Set calibrator to STANDBY.
(23) Repeat technique of (11) through (22) above using negative voltages. Ignore the polarity

(1) Connect calibrator OUTPUT HI, LO and V-GUARD to TI VOLTS INPUT/OHMS
SENSE HI, LO and GD.
(2) Press TI pushbuttons as listed in (a) through (c) below:

(3) Set calibrator for a 100 mV, 1 kHz output.
(4) Allow TI to take several measurements. If TI does not indicate between 99.935 (-3) and
100.065 (-3), perform b(1) through (3) and (12) below.
(5) Repeat technique of (2) through (4) above using settings in table 4. If TI does not indicate
within limits specified, perform corresponding software corrections.
