Notes: Read Accuracy is based on 4-wire input. For 3-wire input, add ± 0.05 Ω assuming all three RTD
leads are matched.
Source Accuracy is based on 0.5 to 3.0 mA excitation current (0.1 mA for pt1000 range)
Resolution: 0.1 °C, 0.1 °F
Allowable excitation current (source): Ni120, Pt100-385, Pt100-392, Pt100-JIS,
Pt200-385: .05 to .80 mA,Pt500-385: 0.05 to 0.80 mA; Pt1000-385: 0.05 to 0.40 mA
RTD Source: Addresses pulsed transmitters and PLCs with pulses as short as 5 ms. SN < 7624001 may
need modification for pulses less than 15 ms.
