Adjustment

Procedure

1. Set the AC Standard output to 5.6 Vac at 1 kHz

2. Set the E1411 range to 5.6 V, and adjust the multimeter

at 5.6 V using:

FUNC:VOLT:AC

VOLT:AC:RANG 5.6

CAL:VAL 5.6

TRIG:DEL .05

CAL?

Verify that the returned calibration error code is 0 (no error).

If not 0, see Table 5-1 for a list of calibration errors and codes.

4. Remove power and disconnect test equipment

Example: AC Voltage

Adjustments

This example performs an AC voltage adjustment for a power line reference

frequency of 60 Hz. Change line 20 to OUTPUT 70903;"CAL:LFR 50" for

50 Hz operation.

If no calibration error occurs (Cal_code = 0 in line 130), the program

displays an "adjustment complete" message. If a calibration error occurs, the

program displays the calibration error (see Table 5-1 for a list of calibration

errors).

When connected to the E1411 multimeter, some AC Standards may exhibit

voltage variations at the start of a measurement. TRIG:DEL .05 (line 110)

adds a 0.8 sec wait before calibration begins to allow settling time for the

AC Standard output. TRIG:DEL .05 is used since the input is sampled 16

times before the calibration is performed. Thus, total delay added = 0.05

seconds x 16 = 0.8 seconds.
