FLUKE FLUKE-773 过程钳形表 (measure 0-100mA/0-30.00 V , source 0- 24.00 mA/ 0-10.00 V DC)

The 773 mA Clamp Meter 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
