Fluke 771 / 772 / 773
ther useful features:
- Sources DC voltage to test input devices that accept a 1-5V or 0 to 10V signal
- Simultaneously measures the mA signal with the clamp and sources a mA signal
- Measures mA signals for PLC and control system analog I/O
- Simulates 4-20 mA signals for testing control system I/O
- Features a detachable clamp with extension cable for measurements in tight locations
- Extends battery life with auto-off and backlight timeout
- Captures and displays changing measurements with Hold function
- Measures 4 to 20 mA signals with in-circuit measurement
- Includes simultaneous mA in-circuit measurement with 24V loop power for powering and testing transmitters
- Offers mA or voltage output linear ramp or 25% step output
- Provides scaled mA output to provide 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
- Applies a mA input signal to a device and measure its’ 4-20 mA output on devices such as valves or mA isolators
- Dual backlit display with both mA measurement and percent of 4 to 20 mA span
- Measurement Spotlight to illuminate hard to see wires in dark enclosure
- Measures 10 to 50 mA signals in older control systems using the 99.9 mA range
- Automatically changes the 4 to 20 mA output for remote testing
