MILLIAMP CALIBRATORS
Models 46, 134
134
ALTEK’s pocket sized milliamp calibrators offer  2-Wire transmitter simu-
lators as well as milliamp sources. Each model give you ease of use,
as well as accuracy and ruggedness both.
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 or 134 in 2-Wire mode. Flip a switch to get instant Full Scale
and Zero outputs. The calibrators...

The Model 334 may also be used when a controller is temporarily
removed for repair or replacement. Simply substitute the Model
334 for the controller and use it as a manual loading station.
SIMULATE 2-WIRE TRANSMITTERS by modulating external power
to pass 4 to 20mA. The Altek Model 334 uses any loop power from
2 to 100 Volts DC. True current design maintains set current
independent of voltage or load changes.
