The Altek POCKETCAL 134-2 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 Two-Wire Transmitter or use the POCKETCAL 134-2 to simultaneously Power & Measure your Two-Wire Transmitters. Toggle the display to show milliamps orpercent of 4 to 20.

SOURCE MILLIAMPS

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

RECALL OUTPUT SETTINGS

The "QUIK-CHEK" pushbuttons provide rapid checking of 4.00, 20.00 and a third point between 0.00 to 24.00 mA. 

CALIBRATE USING LOOP POWER

Check loop wiring and receivers by using the Model 134-2 in place of a 2-Wire transmitter. Simulate a changing process input to check loop response and control settings. The POCKETCAL 134-2 uses any loop power from 3 to 45V DC.  

READ LOOP CURRENT

Check controller outputs or measure the milliamp signal anywhere in the loop. The Model 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.

POWER & MEASURE 2-WIRE TRANSMITTERS

Simultaneously measure the output of a 2-WireTransmitter while using the internal batteries to supply upto 14V DC to power the transmitter. Handy for checking transmitters in the field or on the bench.
