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 chapter. The 5730A Calibrator 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 M
Ω
, plus a short
•
Optional wideband ac voltage from 300
μ
V to 3.5 V into 50
Ω
(-57 dBm to
+24 dBm), 10 Hz to 30 MHz
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.
•
An auxiliary current binding post to calibrate meters with separate current inputs
without the need to move cables.
•
Real-time clock and calendar for date stamping reports and reminders issued to
perform the dc zeros calibration procedure within the required interval.
•
Offset and scaling modes that simplify linearity tests of multimeters.
•
Variable phase reference signal output and phase-lock input.
