Introduction
The Fluke Calibration 5730A Calibrator (the “Product” or the “Calibrator”) can
calibrate a wide variety of electrical measurement instruments. The Product
maintains a high accuracy over a wide ambient temperature range. This
accuracy lets the Product test instruments in any environment, and eliminates the
restrictions to calibrate only in a temperature-controlled standards laboratory.
The Product can calibrate precision multimeters that measure ac or dc voltage,
ac or dc current, and resistance. The Product also is available with a Wideband
AC Voltage option which extends this workload to include RF voltmeters.
This manual contains specifications, calibration procedures, and verification
procedures. 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 a short (0
Ω
) to 100 M
Ω
•
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 Product include:
•
Internal environmentally-controlled references that let the Product 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 Product. This prevents access to levels that may be harmful to equipment
or personnel.
•
Continuous display of Product 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.
