The Piecal 334Plus builds on the Piecal 334 with advanced features unique to PIE calibrators. Easily find current leaks to gound, deteriorating & damp insulation or corroded terminals with patented loop diagnostic technology (US Patent # 7,248,058). Automated stepping (2, 3 or 5 steps) and ramping lets you set the 334Plus at one instrument and check any other point in the loop.
Get better calibrations with a five digit display to 20.000 mA. You can read the display in dim conditions with the built-in backlight. Additional improvements over 334s from other manufacturers include better long term stability, accuracy, reliability & ruggedness plus improved battery life.
PLUS the 334Plus exceeds the performance of many higher cost calibrators to meet today's most demanding requirements while maintaining the familiar, time proven reliability and ease of use of similar calibrators like the Altek 334 & 334A. The PIECAL 334Plus is the new milliamp calibrator standard!
Easily troubleshoot loop problems with patented loop diagnostic technology!

Problem Found & Corrected!
Moisture was found in unsealed juntion box. Loop is operating replacement or recalibration. Hours of troubleshooting saved!
|
![]() |
Recently calibrated two-wire transmitter controlling at 12.000 mA. Control room reports “Loop Out of Tolerance.”
Practical Instrument Electronics recommends a calibration interval of one year. Contact your local representative for recalibration and repair services.
