Fluke 773 Milliamp Process Clamp Meter
- 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
