Introduction
The Fluke Calibration 5730A Calibrator (the “Calibrator” or the “Product”) can calibrate
a wide variety of electrical measurement instruments. The 5730A Calibrator maintains a
high accuracy over a wide ambient temperature range. This accuracy lets the Calibrator
test instruments in any environment, and eliminates the restrictions to calibrate only in a
temperature-controlled standards laboratory. The Calibrator can calibrate precision
multimeters that measure ac or dc voltage, ac or dc current, and resistance. The Calibrator
also is available with a Wideband AC Voltage option which extends this workload to
include RF voltmeters.
Specifications are provided at the end of this manual. The Product is a fully-
programmable precision source of:
• DC voltage to 1100 V
• AC voltage to 1100 V, with output available from 10 Hz to 1.2 MHz
• AC and DC current to 2.2 A, with output available from 10 Hz to 10 kHz
• Resistance in values from 1 Ω to 100 MΩ, plus a short
• Optional wideband ac voltage from 300 μV to 3.5 V into 50 Ω (-57 dBm to
+24 dBm), 10 Hz to 30 MHz (5730A/03) or 50 MHz (5730A/05)
Features of the 5730A Calibrator include:
• Internal environmentally-controlled references that let the Calibrator maintain full
performance over a wide ambient temperature range.
• Automatic meter error calculation obtained through the use of a simple output adjust
knob.
• Keys that multiply and divide the output value by 10. This simplifies work on meters
with calibration points at decade multiples of a fraction of full-scale.
• Programmable entry limits used to restrict the levels that can be entered into the
Calibrator. This prevents access to levels that may be harmful to equipment or
personnel.
• Continuous display of Calibrator specifications at the selected operation point,
calibration interval, and specification confidence level.
