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.
*2-wire: Does not include lead resistance.
3-wire: Assumes matched leads with a total resistance not exceeding 100 Ω.
