Altek 334A Miliamp Loop Calibrator
The Altek 334A Miliamp Loop Calibrator is a go-to tool for checking, calibrating, and measuring all cur signal instruments within a 4 to 20 mA DC loop. It sources and reads from 0.00 to 24.00 mA, simulates a two-wire transmitter, and can power and measure two-wire transmitters simultaneously. It can easily set any value to within 0.01 mA with the speed sensitive digital potentiometer. Altek 334A Miliamp Loop Calibrator can check 4.00, 20.00, and a third customizable point with an accuracy of ±0.006 mA.
Altek 334A Miliamp Loop Calibrator can simulate a changing process input to check loop response and control settings. It checks controller outputs or measure the milliamp signal anywhere in the loop. Altek 334A simultaneously measures the output of a 2-wire transmitter while using the internal batteries to supply up to 27V DC to power the transmitter. This loop calibrator is compact, lightweight and handy for checking transmitters in the field or on the bench. Powered by three 9V alkaline batteries, Altek 334A Miliamp Loop Calibrator can source 20 mA for over 20 hours and simulate/read for 150 hours.
