Table 1-1. Keep in mind, however, that calibrator uncertainty will add to the uncertainty of each
measurement.

Recommended verification equipment
Fluke 5700A Calibrator:
AC voltage
DC voltage (1kHz, 50kHz)
100mV ±14ppm 100mV ±200ppm
1.0V ±7ppm 1.0V ±82ppm
10V ±5ppm 10V ±82ppm
100V ±7ppm 100V ±90ppm
1000V ±9ppm 700V ±85ppm
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.
