The Fluke 5720A is a multifunction calibrator designed to address the electrical calibration workload. The 5720A-03 sources direct and alternating voltage and current and resistance. A wideband voltage option (03) extends overall AC bandwidth to 10 Hz to 30 MHz to cover to RF voltmeters.
Features:
- 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
- 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 'spec' key that provides the capability of displaying the instrument's specification at the selected operating point, calibration interval, and specification confidence level
- Offset and scaling modes that simplify linearity testing of multimeters
- Variable phase reference signal output and phase-lock input
