1-4 Performance Verification

Recommended test equipment

Table 1-1 summarizes recommended verification equipment. You can use alternate equipment
as long as that equipment has specifications at least as good as those listed in Table 1-1. Keep in
mind, however, that the calibrator 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
Keithley 3930A or 3940 Frequency Synthesizer:
1V RMS, 1kHz, ±5ppm
Stanford Research Systems DS-360 Ultra Low Distortion Function Generator:
1kHz, .0.95V RMS sine wave, -100dB THD
Miscellaneous Equipment:
Double banana plug to double banana plug shielded cable
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.
Verification at 220V, 50kHz using only the 5700A calibrator is adequate for most applications.
