* Specifications same as model 3B45.

1 For a 0 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 3B45-00 and 3B46-00 models, using the AC1310 ranging card.

5 +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.

Specifications subject to change without notice.
