(11) AVG to off.
(12) ZERO to on.
b. Press EXT GD IN pushbutton to in.
c. Allow at least 2 hours for TI to warm up and stabilize.
8. Dc Voltage
a. Performance Check
(1) Connect calibrator OUTPUT HI, LO and V-GUARD to TI VOLTS INPUT/OHMS
SENSE HI, LO and GD.
(2) Press TI RANGE ↑ or ↓ pushbutton to select the 100 mV range.
(3) Set calibrator for a 100 mV dc output. If TI does not indicate between 99.995 (-3) and
100.005 (-3), perform b below.
(4) Repeat technique of (2) and (3) above using settings listed in table 3. If TI does not
indicate within limits specified, perform b below.

b. Dc Software Corrections
(1) Set calibrator to STANDBY and disconnect from TI.
(2) Slide rear panel CALIBRATION switch to ON and verify that AVG/(CAL) annunciator
is flashing.
NOTE
When in the calibration mode, input power must not be
cycled ON or OFF. Before cycling power OFF, verify that
AVG/(CAL) annunciator is not flashing. Before cycling
power ON, check that rear panel calibration switch is OFF.
