Introduction - Fluke Calibration 5730A Service Manual

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. The Product
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.
This manual contains specifications, theory of operation, calibration procedures,
and verification procedures, list of replaceable parts, and repair instructions. The
repairs in this manual are detailed to the modular level. For any repairs other
than module replacement, send the Product back to Fluke Calibration for service.
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 Product 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.
