Fits high-type-count thermocouple and milliamp work where you need a PIE 422/422Plus covering 14 TC types plus mV/mA with ±(0.008%+0.006 mV) TC accuracy and patented ground-leak diagnostics on 422Plus.
Key advantages
- TC types — J/K/T/E/R/S/B/N/G/C/D/L/U/P
- TC accuracy — ±(0.008% of reading + 0.006 mV); CJC ±0.05 °C class
- mA — 0–24 mA source/read; 2-wire simulate; 24 V PWRM; ≤±(0.02%+0.003 mA)
- Diagnostics — Ground-leak / loop diagnostic (422Plus); HART 250 Ω
- Form — Handheld graphic calibrator
Typical applications
- Multi-type TC calibration routes.
- Loop mA source with TC in one tool.
- Ground-leak troubleshooting (422Plus).
Selection guide
- 422 vs 422Plus — Diagnostics need
- TC set — Exotic types G/C/D
- mA power — 24 V PWRM
- HART resistor — 250 Ω
Common mistakes
- Buying 322 when 14-type count is required.
- Ignoring leak diagnostic on troubled loops.
- Wrong CJC connection.
