Loop detective multifunction calibrator

The PIE Model 830 is more than a multifunction calibrator. It is also a loop detective that is able to diagnose common problems that other test equipment cannot find.

If you have a flooded junction box or unknown ground faults, PIE’s Loop Diagnostic technology will detect it. Or use the LoopScope to see at a glance all the parameters – milliamps, voltage and resistance – in the loop. Setup the PIE Model 830 as an isolated universal transmitter and turn on the Loop Diagnostics. The display will tell you the exact sensor input, the current output and if there is any uncontrolled current in the loop due to a ground fault, corrosion bridge or moisture. If the control system does not see a problem when the 830 is acting as a transmitter, you can replace the faulty transmitter. With RTDs, the 830 automatically detects which of the 2, 3 or 4 wires are connected and unbroken quickly alerting you to a sensor problem.

Diagnostic features are covered by US Patent #7,248,058.  The PIE Model 830 is the first calibrator with five troubleshooting tools. It can detect hidden loop problems, check all loop parameters at once with their LoopScope technology, plus it troubleshoots sensor connections and find broken wires. The PIE 830 can also swap out faulty transmitters to diagnose control issues plus troubleshoot wiring problems without a multimeter.
