The OMEGA™ CA450 Process
Multimeter is a portable test
instrument to combine a digital
RMS multimeter and a loop
calibrator to give process
technicians the same functionality
in one tool. The model CA450
provides 24V loop power, reducing
the need for carrying a separate
power supply when performing
transmitter testing. And with its
built-in, selectable 250? Hart
resistor, it also eliminates the need
for a separate resistor. Process
technicians can now do the same
job while carrying less equipment.
