Fluke 5720A Multi-Function Electrical Calibrator

The Fluke Model 5720A Series II calibrator is a precise instrument that calibrate a wide variety of electrical measuring instruments. This calibrator maintains high accuracy over a wide ambient temperature range, allowing it to test instruments in any environment, eliminating the restrictions to calibrate only in a temperature-controlled standards laboratory. With a 5700A/5720A Series II, you can calibrate precision multimeters that measure ac or dc voltage, ac or dc current, and resistance. The 5720A Series II operates in a similar manner to the 5700A Series II, the difference is that the 5720A Series II has a considerably higher specified accuracy. Option 5700A-03 Wideband AC Voltage, which is available for both the 5700A Series II and the 5720A Series II, extends this workload to include rf voltmeters.

Features:

• Internal environmentally-controlled references allowing the calibrator to maintain full performance over a wide ambient temperature range.
• Automatic meter error calculation obtained through using a simple output adjust knob; the display shows linearity, offset, and scale errors.
• Keys that multiply and divide the output value by 10 to simplify work on meters with calibration points at decade multiples of a fraction of full-scale.
• Programmable entry limits used for restricting the levels that can be keyed into the calibrator, preventing access to levels that may be harmful to equipment or personnel.
• A space key that provides the capability of displaying the instrument’s specification at the selected operating point, calibration interval, and specification confidence level.
• An auxiliary current binding post that allows you to calibrate meters with separate current inputs without moving cables.
• Real-time clock and calendar for date stamping reports.
• Offset and scaling modes that simplify linearity testing of multimeters.
• Variable phase reference signal output and phase-lock input.
• Interface for the Fluke 5725 Amplifier.
• Standard IEEE-488 (GPIB) interface, complying with ANSI/IEEE Standards 488.1- 1987 and 488.2-1987.
• Standard IEEE-488 (GPIB) interface, complying with ANSI/IEEE Standards 488.1- 1987 and 488.2-1987.
• Standard IEEE-488 (GPIB) interface, complying with ANSI/IEEE Standards 488.1- 1987 and 488.2-1987.
• Standard IEEE-488 (GPIB) interface, complying with ANSI/IEEE Standards 488.1- 1987 and 488.2-1987.
• A traceable calibration procedure for all modes and ranges that requires only 10V, 1Ω, and 10 kΩ external standards, with only occasional independent verification.
