FLUKE 773 Milliamp Process Clamp Meter

The new Fluke 772 and 773 Milliamp Clamp Meters join the Fluke 771 to deliver a comprehensive range of test and measurement capabilities. Now technicians in process plants, industrial plants, commercial buildings and automation commissioning teams can choose exactly the range of capabilities they need, at a price that makes sense.

These precision tools are designed for instrumentation technicians, contractors and process vendors who install and commission instruments, process and automation technicians, commercial electricians and automation specialists who do mA loop troubleshooting on process control circuits, instruments and automation I/O.

The Fluke 771, 772 and 773 Milliamp Clamp Meters are engineered to accurately measure the minute amounts of current (4 to 20 mA signals) that flow through control system circuits, without having to shut down the system, break the circuit and insert a test instrument. Instead, sensitive current clamps placed on the wire detect and measure the current flowing through. Fluke is the only manufacturer making process mA clamp meters that don’t break the loop.

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
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
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
