Features

The 772 and 773 expand upon the capabilities of the popular 771 mA Clamp Meter. Now all you have to do is decide which model will help you save the most time. The Fluke 771, 772 and 773 features:

Best in class 0.2 % accuracy 0.01 mA resolution and sensitivity Measure 4 to 20 mA signals without ¡±breaking the loop¡± Measure mA signals for PLC and control system analog I/O Dual backlit display with both mA measurement and percent of 4 to 20 mA span Measurement Spotlight illuminates hard to see wires in dark enclosures Detachable clamp with extension cable for measurements in tight locations Measure 10 to 50 mA signals in older control systems using the 99.9 mA range Automatically change the 4 to 20 mA output for remote testing Power saving features, auto-off, backlight timeout extend battery life Hold function captures and displays changing measurements

772 and 773 add:

Measure 4 to 20 mA signals with in-circuit measurement Simultaneous mA in-circuit measurement with 24V loop power for powering and testing transmitters Source 4 to 20 mA signals for testing control system I/O or I/Ps mA output linear ramp or 25% step output Automatically change the 4 to 20 mA output for remote testing

773 Only Features:

DC voltage measurement to verify 24V power supplies or voltage I/O signals Source DC voltage to test input devices that accept a 1-5V or 0 to 10V signals Scaled mA output provides a continuous mA signal that corresponds to the 4 to 20 mA signal measured by the mA clamp Enables milliamp signal logging to a separate logging device without breaking the loop Output mA signal enables a logging DMM or other device to record the 4- to 20 mA signal without breaking the loop mA in/out: simultaneously measure the mA signal with the clamp and source a mA signal Apply a mA input signal to a device and measure its¡¯ 4-20 mA output on devices such as valves or mA isolators Voltage output linear ramp or 25% step output Automatically change the voltage output for remote testing
