General Information
Get more tools in a smaller calibrator
Carry eight single function calibrators
plus a milliamp calibrator with loop supply
plus a loop troubleshooter in the palm of your hand!
Milliamp • Voltage • Frequency • pH • Ohms
Thermocouples • RTDs • Pressure
Loop Diagnostics • Transmitter Supply
1
Detect ‘hidden’ loop problems
Quickly diagnose troublesome ground faults & current leak-
age with patented Loop Diagnostic technology. These prob-
lems are undetectable with other instruments!
2
Check all loop parameters at once with LoopScope™
Simultaneously displays current, voltage and resistance
to let you know the condition of a live loop. Finds prob-
lems with power supplies & loops with too many loads.
Patented by PIE!
3
Automatically detect 2, 3, or 4 wire RTDs
Trouble shoot sensor connections and find broken wires with
patented technology. LCD indicates which of the four wires
are connected to an RTD sensor.
4
Swap out faulty transmitters to diagnose control issues
Easily setup the 830 as a universal isolated transmitter for
Thermocouple, RTD, frequency, millivolt, resistance or pres-
sure. If the loop is back under control you know the
transmitter was faulty. Turn on the LoopScope to
simultaneously see the loop current, loop voltage and loop
loads for troubleshooting.
5
Troubleshoot wiring problems without a multimeter
Built in continuity checker with ‘beeper’ quickly finds broken
wires or shorts in instrumentation wiring. Also handy for
checking operation of relays and controller outputs.
