ThermoWorks RTD Simulator Check or calibrate any RTD instrument. Competing calibrators typically cost 2 or 3 times more. For testing RTD instruments, choose our VA720. Simulate and measure 7 different RTD types in 2-wire, 3-wire, or 4-wire mode. Large single-function buttons and a Accuracy (Input/Output): Pt100(4 Wire):±0.3°C, Pt1000(4 Wire): ±0.2°CRange: 0 to 3200 ohmIncluded with Meter: 4 leads and aligator clips, protective case, batteries, manual and calibration certificate.Resolution: 0 ohm or 0.1°C max PT100 simulator for simulating 100 ohm RTD temperature Connecting the RTD simulator: The RTD simulator has 4 connections so it is suitable for replacing 2-wire, 3-wire and 4-wire PT100 temperature sensors. The wiring can be connected to the screw terminals at the back side. The PT100 simulator is intended for panel mounting. PT100 RTD simulator operation.
