General Information

Simulate 2-wire transmitters to calibrate receivers,
recorders, controllers, indicators and computers. Loop
power eliminates the need for batteries. Loop current
is clamped at the key value you select. Accuracy is
±0.08% of 4 to 20 mA, even with changes in load and
supply voltage.
Switch settings of 0, 25, 50, 75 and 100% give you
fast, full range checkout of instrument or system. The
single switch and palm sized case have been
designed for simple, one handed operation. Just clip
the built-in leads to the 2-wire terminals in the field,
junction box or control room.
When you check out receivers, recorders or
controllers in a 2-wire 4 to 20mA loop, simply
disconnect the 2-wire transmitter and hook up a
Model 46. Flip a switch to get instant full scale and
zero outputs. The calibrator operates just like a 2-wire
transmitter by modulating the external power supply
voltage into a 4 to 20mA signal.
The Model 46 receives all of its operating power from
the loop. This lets you operate continuously for days
when long term loop testing is required. Use it as a
manual loading station when a controller needs repair
or replacement. Minimize process shutdowns
installing a new controller.
