PIE 820 / 820PM Multifunction Process Calibrator

Pocket six-function process calibrator for mA, V, thermocouple, ohms, RTD, and frequency — with built-in 24 V loop supply, HART 250 Ω, continuity beeper, and EZ-DIAL / EZ-CHECK stepping.

Key advantages

Six functions in one — source/read mA, V, mV, TC, ohms/RTD, and frequency; continuity beeper for wiring checks.
Loop tools — 0…24 mA / 0…10.25 V / 0…80 mV source; read to 24 mA / 60 V; 2-wire simulate; built-in 24 V and 250 Ω HART resistor.
Temperature direct — TC types J, K, T, E, R, S, B, N, G, C, D, L, U, P; RTD Pt100/1000, Cu 10/50, Ni 110/120.
Technician kit — rubber boot, deluxe hands-free case, and mV/RTD leads on the standard package.

Typical applications

Replacing a toolbox of single-function calibrators for transmitter and loop checkout.
Field calibration of TC/RTD transmitters, PLC/DCS inputs, and frequency/vibration pickups.
HART loop hookups without a separate resistor pack.

Selection guide

820 vs 820PM — Confirm panel-mount / PM variant needs on RFQ (SKU lists both).
mA/V — Source 0…24.00 mA, 0…10.25 VDC, 0…80.00 mV; read 24 mA / 60 V / 80 mV.
Frequency — Source & read to 2000 CPM, 999.99 Hz, 9999.9 Hz, 20.000 kHz.
Stepping — 2/3/5/11 steps or ramp; 5…60 s step/ramp times; three EZ-CHECK setpoints.
Package — Standard (boot + case + leads) vs basic — state preference on RFQ.

Common mistakes

Ordering 820 when dual-channel diagnostic features of PIE 830 are required.
Skipping pressure modules when pressure work is on the job — 820 is electrical/temperature/frequency only.
Forgetting HART 250 Ω — built in on 820.

FAQ

Q: How does 820 differ from 830? A: 820 is a single-channel six-function calibrator. 830 adds dual isolated channels and diagnostic tools (LoopScope, leak detect, universal transmitter mode). State which duties you need.

Q: What should I send for a quote? A: 820 vs 820PM, package, quantity. Compatible with systems using PIE 820 if you need a drop-in check — we do not claim authorized-dealer status.
