Diagnostic Process Calibrator


Quickly find hidden loop problems with the world’s first multifunction calibrator with built-in troubleshooting tools. Become a loop detective able to diagnose common problems that technicians carrying other test equipment just can’t find. Unique to the PIE Model 830 are troubleshooting features and the ability to operate as an isolated universal diagnostic transmitter. Connect the process T/C or RTD sensor and the 830 acts as a linear or non-linear 2-wire transmitter with a built-in LoopScope simultaneously displaying the sensor input and the current, voltage and resistance of the loop. Or add a pressure module to swap out a linear or square root pressure transmitter.  For the first time you can see how the loop is REALLY functioning and verify the power supply has enough capacity to power all the devices in the loop. Patented ‘Loop Diagnostic’ technology (Patent 7,248,058) uses the internal power supply to drive the loop while finding ground faults and leakage current due to corrosion or condensation in your conduits and junction boxes. 

The 830 finds sensor problems by auto detecting 2, 3 or 4 wire RTD’s and a continuity beeper to locate problems in loop wiring without grabbing a multimeter. Identical in size to PIE single function calibrators, the 830 is much smaller and lighter than other multifunction calibrators. The toolbox tough design includes a backlit display for use in dark environments, protective rubber boot with built in stand, hands free carrying case and test leads. The easy to use double click menu system allows for quick setup, fast switching between functions and pre-programming of set points and step/ramp times. All standard functions including sourcing and reading 14 T/C types, 9 RTD curves, volts, ohms and frequency plus simulate pH and read pressure are shown along with milliamps on the display. The display allows you to visually monitor not only the various sensor signals but also the control loop current and diagnostics. Accuracy is ±0.02% of reading + 0.01% of Full Scale with guaranteed compatibility with modern instrumentation. Choose from 32 differential, gauge, compound or absolute pressure modules and three hand pumps for a complete calibration package. A compact carrying case holds the 830, pressure module and accessories for easy hands free operation.
