PIECAL 830 2 Channel Multifunction Diagnostic Process Calibrator


The pocket sized PIECAL 830, by Practical Instrument Electronics (PIE) replaces a toolbox of single function devices; dual channels allows for use of only 1 calibrator instead of 2! 

  • millamp
  • Voltage
  • Thermocouples
  • Ohms
  • RTD
  • Hz (Frequency)
  • pH
  • Pressure (via optional external pressure module)

The intuitive EZ-DIAL Double Click Menu makes it easier to setup than many other multifunction calibrators and uses the same menus as the single function PIECAL Evolution Calibrators. Icons on the display indicate where to plug in the test leads.

It's also the First Multifunction calibrator with 5 troubleshooting tools including a universal transmitter:

  1. Detect hidden loop problems with Patented Current leak detection technology
    Quickly diagnose troublesome ground faults & current leakage with patented Loop Diagnostic technology. These problems are undetectable with other instruments!
  2. Check all loop parameters at once with the LoopScope
    Simultaneously displays current, voltage and resistance to let you know the condition of a live loop. Finds problems 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 temperature, frequency, millivolt or pressure. If the loop is back under control you know the transmitter was faulty. Turn on the LoopScope to simultaneously see the loop current, power supply 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.
  • Use it as a milliamp and voltage calibrator
    Source 0.00 to 24.00 mA, 0.00 to 10.25 VDC, -20.000 to 99.999 mV and -500.00 to 999.99 mV
    Read to 24.00 mA, 0.0 to 60.0 VDC, +/- 99.999 mV and +/- 999.99 mV
    Simulate 2 Wire transmitters
    Power up transmitters and loops with built in 24 V power supply
    Simplify HART hook ups with built in 250 ohm resistor
  • Calibrate directly in temperature (°C & °F)
    The PIE 830 works with the instruments you use.
    Thermocouple types J, K, T, E, R, S, B, N, G, C, D, L (J DIN), U (T DIN) and P (Platinel II)
    RTD types Pt 100 Ohm (3850, 3902, 3916, 3926) & 1000 Ohm (3850)
    Copper 10 & 50 Ohm, Nickel 110 and 120 Ohm
  • Checkout flow and vibration systems
    Source & read frequency to 2000 CPM (Counts-Per-Minute), 999.99
    Hz, 9999.9 Hz, & to 20.000 kHz
  • Simulate pH probes into transmitters & analyzers
    Source from 0.000 to 14.000 pH @ 25°C (77°F) corresponding to +414.12 to -414.12 mV
  • Measure pressure with optional pressure modules
    32 modules for gauge, differential, compound and absolute pressure
  • Quickly set any three outputs plus automatic stepping & ramping
    Easily set any value quickly with the adjustable “DIAL”; store any three output settings for instant recall with the EZ-CHECK™ switch.
    Choose between 2, 3, 5 & 11 steps to automatically increment the output in 100%, 50%, 25% or 10% of span.
    Select RAMP to smoothly increase and decrease the output between Zero and Span.
    Set step/ramp time to match your system from 5, 6, 7, 8, 10, 15, 20, 25, 30 and 60 seconds
  • Measure temperature sensors, frequency pickups, loop currents, voltage levels & pressures
    Check the values of your process sensors. Instantly recall MAX and MIN values to see process variability
