 Battery Life 3x9 volt alkaline batteries source 20 mA for over 20
hours, 12 mA for over 33 hours; 2-wire simulate and read for 150 hours.
Much longer than NiCd batteries or calibrators with a single 9 V
battery!

The
 Altek Model 334A will check, calibrate and measure all your current
signal instruments in a 4 to 20 milliamp DC loop. Use at every point in
your loop. Source & Read 0.00 to 24.00 mA, Simulate a 2-wire
transmitter or use the Model 334A to simultaneously power & measure
your 2-wire transmitters. Toggle the display to show milliamps or
percent of 4 to 20.

Calibrate recorders, digital indicators,
stroke valves or any other instruments that get their input from a 4 to
20 mA loop. Easily set any value to within 0.01 mA with the speed
sensitive digital potentiometer
