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 3B30-00 and 3B31-00 models, using the AC1310 ranging card.

5 When used with the CJC temperature sensor provided on the 3B Series backplane.

6 +24 V dc loop power is required for driving the current output at loads up to 850

Ω. 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.
