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!
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
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.
