The PIE 311-PLUS is the only calibrator that combines all the functions of a diagnostic milliamp calibrator with the accuracy of a laboratory RTD calibrator. You can quickly diagnose ground fault and current leakage often caused by water in conduits and junction boxes with patented loop diagnostic technology (patent # 7,248,058).

No competitor's calibrator is compatible with as many process instruments. Connect directly to RTD inputs of smart transmitters, PLCs, DCS and multichannel recorders and verify their outputs or displays. You can troubleshoot sensor connections and find broken wires with the patented technology. Connect your 2, 3, 4 wire RTDs and the PIE 311-PLUS automatically detects the connections. Secondary display shows the resistance value corresponding to the RTD temperature.

When you have a RTD input problem that is difficult to diagnose, the PIE 311-PLUS makes it easy. When you connect the meter directly to the RTD sensor it will indicate on the display which wires are connected. This quickly points out if there is a problem with the wiring or with the sensor itself. If no problem is found with the sensor connect the PIE 311-PLUS to the sensor input connections on the instrument to see if it is working properly. Secondary displays show you the resistance value of the RTD plus the magnitude and direction of the excitation current used by the instrument to measure the RTD sensor. If no excitation current is detected then there is a problem with the instrument.

The PIE 311-PLUS allows for fast calibration with automatic output stepping. You can choose between 2, 3, 5, 11 and 21 steps to automatically increment the  outputs in 100%, 50%, 25%, 10% or 5% of span. Select the step time to match your system from 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 60 seconds.
