Recommended test equipment

equipment as long as that equipment has specifications equivalent to or better than those

than corresponding Model 2790 specifications. Keep in mind, however, that calibrator

uncertainty will add to the uncertainty of each measurement.

Recommended verification equipment

Fluke 5700A Calibrator:

100mV:±14ppm

Fluke 5725A Amplifier:

AC Voltage, 50kHz: 700V, ±375ppm

DC Current, 3A, ±500ppm

AC Current, 1kHz, 3A, ±457ppm

Stanford Research Systems DS345 Function Generator:

1V RMS 1kHz, ±5ppm

General Radio 1433-T Precision Decade Resistance Box:

10Ω to 400Ω, ±0.02%

Miscellaneous Equipment:

Double banana plug to double banana plug shielded cables (2)

BNC to double banana plug shielded cable

NOTE: The Fluke 5725A amplifier is necessary only if you wish to verify the 750V AC range at 50kHz and 3A AC and

DC current ranges at 3A. Verification at 220V, 50kHz, and 2.2A on the current ranges using only the 5700A

calibrator is adequate for most applications.
