The Altek Pocketcal 134-2 will check, calibrate and measure all of 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 two-wire transmitter or use the 134-2 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.
The “Quik-Chek” pushbuttons provide rapid checking of 4.00, 20.00 and a third point between 0.00 to 24.00 mA.
Check loop wiring and receivers by using the 134-2 in place of a 2-wire transmitter. Simulate a changing process input to check loop response and control settings. The 134-2 uses any loop power from 3 to 42 VDC.
Check controller outputs or measure the milliamp signal anywhere in the loop. The 134-2 measures 0.00 to 24.00 mA signals with much greater accuracy than a typical multimeter. Toggle the display to show milliamps or percent of 4 to 20.
Simultaneously measure the output of a 2-wire transmitter while using the internal batteries to supply up to 14 VDC to power the transmitter. Handy for checking transmitters in the field or on the bench.
