Chi tiết
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
