Product Description
Calibrate and troubleshoot all the signals in a standard 4 to 20 milliamp process control loop with Altek?s Model 434 Milliamp Calibrator. A 24 mA Source, mA meter, 2-Wire Transmitter Simulator and a DC Volt meter in one compact unit enables a single tool to perform most calibration and troubleshooting functions.

Calibrate controllers, recorders or other devices in 4 to 20 or 0 to 20 mA loops. Six ?AA? batteries provide hours of continuous use. The batteries last several time longer than calibrators with a single 9V battery! .

Check out the response of a loop by using the Model 434 in place of a 2-wire transmitter. The Model 434 modulates the current passing through the loop just like a transmitter, but with manual control.

Simultaneously supply power to a 2-wire transmitter while displaying the 4-20 mA output signal. The Model 434 supplies a nominal 24 Volts DC to the 2-wire transmitter while displaying the transmitter?s output.

Check 24 Volt
