Fluke 772 - Specifications Manual

Technical Data
Fluke 772 and 773
Milliamp Process
Clamp Meters
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 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
