Main characteristics
Functions of Fluke 773 mA clamp meter:
Better 0.2% accuracy
Resolution and sensitivity of 0.01 mA
4-20 mA signal can be measured without "disconnecting the circuit"
Measuring mA signal of PLC and control system simulating I/O
Double Backlight Display Displays Displaying mA Measurements and 4-20 mA Range Percentage
Measuring spotlights to illuminate hard-to-find lines in dark chassis
A detachable caliper with an extension line can be measured in a narrow space.
Measurement of 10-50 mA signals in old control systems using 99.9 mA range
Automatically change 4 to 20 mA output for remote testing
Power-saving functions such as automatic shutdown and backlight overtime can prolong battery life
"Maintain function to capture and display changing measurements
Measuring 4-20 mA Signal by Pen Access Loop Measuring Function
Synchronized 24V circuit power supply and measurement circuit mA signal, which can supply power for transmission device and test it.
Output 4 to 20 mA signal source to test control system I/O or I/P
MA Output Linear Gradient or 25% Step Output
Automatically change 4 to 20 mA output for remote testing
DC voltage measurement, verifying 24V power supply or voltage I/O signal
Provide DC voltage sources to test input devices that can accept 1-5V or 0-10V signals
Proportional mA output provides a continuous mA signal corresponding to the 4-20 mA signal measured by the mA clamp meter.
The milliampere signal can be recorded to a separate recording device without the need to disconnect the circuit.
Output mA signals allow log digital multimeter or other devices to record 4 to 20 mA signals without disconnecting the circuit
MA Input/Output: Measure the mA signal by non-disconnected clamp meter and output the mA signal source
Apply the mA input signal to the equipment, and then measure its 4-20 mA output on the valve or mA isolator and other equipment.
Voltage Output Linear Gradient or 25% Step Output
Automatically change the voltage output for remote testing
