Troubleshooting clamp meters for control circuits
July 1st 2009 Fluke's two new milliamp
clamp meters are designed 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 new 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 instrumentation
technicians, contractors and process
and control installers who carry out
milliamp loop troubleshooting on
process control circuits, instruments
and automotive systems.
The meters are engineered to
accurately measure the 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 the current flowing
through. In addition, the 772 and
773 can be used to simultaneously
source, simulate and measure
milliamp signals in a broken circuit,
negating the need for additional
tools. More articles from Fluke (U.K.) Ltd: |
