NOTE: The following % of error data will not be utilized if indications in steps 4 and 5 are within limits:
1Record multimeter indication, then convert to % of error by multiplying value by 10. If out of tolerance, perform step 5
above prior to performing b (7) through (9) below.
2Record multimeter indication, then convert to % of error by multiplying value by 100.
3If indication is within limits, adjust TI VOLTAGE dials for the best null indication on multimeter. Record resulting TI
VOLTAGE dial setting for use in (15) below.
(10) Connect equipment as shown in figure 2.
