PIE 434 mA Loop Diagnostic Calibrator

The PIECAL 434 will accurately check, calibrate and measure all your current signal instruments in a 4 to 20 mA DC loop. The 434 can source and read from 0.000 to 24.000 mA, measure from -60.00 to +60.00V DC, as well as simulate or simultaneously power and measure 2-wire transmitters to 24V DC.

PIE's loop diagnostic technology enables the 434 to detect current leakage from ground faults, moisture or corrosion. While powering the loop, the 434 uses a patented ground leak detection system to display any uncontrolled current, helping you troubleshoot and diagnose errors.The 434 enables faster calibrations with a three output check switch, 2 speed potentiometer and automatic output stepping and ramping. A built-in 250Ω resistor also powers HART® transmitters and simplifies hook-ups with HART® communicators.

Compact, lightweight and easy to use, the rugged and reliable 434 is backed by PIE's 3 year warranty. The PIE range of calibrators are built by the same engineering team that stood behind the Altek brand for over 20 years, and the faithfulness and dependability of these little calibrators is legendary. Check one out today - you won't be dissapointed!
