NOTE
If multimeter does not have the keyboard overlay with the
NULL function preprogrammed, you will have to access the
MATH function through the MENU command and enable
MATH NULL.
(6) Disconnect calibrator and connect TI OUTPUT to multimeter Input (2 WIRE)
terminals.
(7) Set TI as listed in (a) through (g) below:
(a) FREQUENCY RANGE-Hz switch to 1 kHz.
(b) FREQUENCY dials to 1.0000.
(c) VOLTAGE RANGE switch to 1 V.
(d) VOLTAGE dials to 1.000000 V.
(e) VOLTAGE ERROR-% switch to OFF.
(f) SENSE switch to INT.
(g) MODE switch to OPER.
(8) Allow multimeter to take at last three readings (samples). Multimeter will
indicate 0 V (0.00122 V); if not, perform steps 1 and 2 of table 6 and b (1) through (5)
below.
(9) Repeat technique of (2) through (8) above for remaining steps listed in table 6,
using settings and values specified.
