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 3B18-00 model, using the AC1310 ranging card.
5
+24 V dc loop power is required for driving the current output at loads up to 850
. If a current output load of 400
or less is applied, +15 V dc is sufficient for loop power. If only
voltage output is used, loop power is not required.
