Fits temperature transmitter and instrument calibration where you need a PIE 525B to source and read thermocouple, RTD, ohms, and millivolts with automated steps.
Key advantages
- TC + RTD source/read — Source & read thermocouple, RTD, ohms, millivolts
- Thermocouples — J K T E R S B N G C D L U P; −13.0000 to +80.0000 mV
- RTDs — Pt 10…1000 Ω (3850) plus Pt100 variants, Cu, Ni; automatic 2/3/4-wire detection
- Accuracy — TC ±(0.008% + 0.006 mV); CJC ±0.05 °C; RTD 3/4-wire ±(0.015% + 0.05 Ω)
- Automation — Auto-step 2/3/5/11 or ramp; EZ-CHECK three presets; 0.1°/0.01° selectable
Typical applications
- Thermocouple and RTD transmitter calibration.
- Automated step/ramp checks with EZ-CHECK presets.
- Field temperature loops needing source and read in one tool.
Selection guide
- Sensor types needed — TC list and RTD curves
- Wiring — 2/3/4-wire RTD (ConnectSense automatic detection)
- Step/ramp timing — 5–60 s step times
Common mistakes
- Treating 525B as a pressure calibrator — it is TC/RTD/Ω/mV.
- Ignoring cold-junction uncertainty on TC work.
- Using 2-wire RTD without accounting for lead resistance when 3/4-wire is available.
When to RFQ / what to tell us
- TC/RTD types used on site.
- Quantity; ship-to.
