General Information Get more tools in a smaller calibrator Carry eight single function calibrators plus a 4-20/10-50 milliamp calibrator with loop supply plus a loop troubleshooter in the palm of your hand! in ar Detect ‘hidden’ loop problems Quickly diagnose troublesome ground faults & current leakage with patented Loop Diagnostic technology.
ar y General Information The PIE Model 850 is more than a multifunction calibrator. It is also a loop detective that is able to diagnose common problems that other test equipment just can’t find. Have a flooded junction box or unknown ground faults? Our 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. Diagnostic features are covered by US Patent #7,248,058.
