Practical Instrument Electronics 830 - Manual (Page 4)

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 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.
Stop throwing away perfectly good transmitters
only to find the problem is somewhere else in the
loop. Setup the PIE Model 830 as an isolated
universal transmitter and turn on the Loop
Diagnostics. The display will tell you EXACTLY the
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 sees no problem when the 830 is acting as
a transmitter THEN 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
