Troubleshooting role
May 1st 2011 Fluke has introduced two
milliamp clamp meters to
help technicians test
critical automation and
control circuits without
breaking the circuit or
interrupting operations,
which can offer savings in
time and money.
The Fluke 772 and 773
Milliamp Clamp Meters
join the Fluke 771 to deliver a range
of cost effective test and
measurement capabilities. These
precision tools are designed for those
who carry out milliamp loop
trouble-shooting on process control
circuits, instruments and automotive
systems.
The meters accurately measure
minute amounts of current (4mA to
20mA signals) that flow through
control system circuits, without
having to shut down the system,
break the circuit and
insert a test instrument.
Instead, sensitive current
clamps placed around
the wire detect and
measure current flowing
through.
The Fluke 772 and 773
can be used to
simultaneously source,
simulate and measure
milliamp signals in a broken circuit,
negating the need for other tools.
Fluke 773 will also source and
measure DC voltages for troubleshooting
voltage input and output
devices; will power a transmitter for
independent checking of its mA
output signal; and will provide a
scaled output signal to provide
datalogging by a Fluke 280 Series
Digital Multimeter, for example. More articles from Fluke (U.K.) Ltd: |
