Technical Data

Use the Fluke 772 and 773 to:

Measure 4 to 20 mA signals without ”breaking the

•

loop” just like the innovative and popular Fluke 771
Process Milliamp Clampmeter

Source 4 to 20 mA signals for testing control

•

system I/O or I/Ps

Simulate 4 to 20 mA signals for testing control

•

system I/O

Measure 4 to 20 mA signals with in-circuit

•

measurement

Simultaneously measure mA in-circuit with 24 V

•

loop power for powering and testing transmitters

Source mA output signals in a linear ramp or 25 %

•

step output
– Automatically change the 4 to 20 mA output for

remote testing

Power saving features, auto-off, backlight timeout

•

extend battery life

Fluke 773 features:

DC voltage measurement to verify 24 V power

•

supplies or voltage I/O signals

Source dc voltage to test input devices that accept

•

a 1 to 5 volt or 0 to 10 volt signal

Scaled mA output provides a continuous mA signal

•

that corresponds to the 4 to 20 mA signal measured
by the mA clamp
– Output mA signal enables a logging DMM (289)

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 to 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
