1 _{For a 0 mA to 20 mA range, a typical minimum output current is 10 µA.}
2 _{Includes the combined effects of repeatability, hysteresis, and nonlinearity.}
3 _{With respect to the voltage output.}
4 _{A wide range of custom zero suppression and span is available with the 3B20-00 model, using the AC1310 ranging card.}
5 _{+24 V dc loop power is required for driving the current output at loads up to 850Ω. If a current output load of 400Ω or less is applied, +15 V dc is sufficient for loop power. If only}
voltage output is used, loop power is not required.
