Current Setting
There are four current output settings available on the AMP330 : 0-16 mA, 0-20 mA, 4-20 mA
(default), and 5-25 mA. To select the current, simply flip the DIP switches to the appropriate
configuration.

Advanced Span and Zero Adjustment
Adjusting the Zero
At times, when using a signal conditioner, it is necessary to offset the zero. The AMP330
makes this simple. The zero can be adjusted approximately ±10% of R.O. by using the
potentiometer on board.
Adjusting the Span
The input jumpers vary from 0.5 mV/V to 10.0 mV/V. This allows for a large variety of input
ranges. However, it sometimes happens that the rated output from the sensor is not exactly 2.0
mV/V or 3.0 mV/V. The AMP330 has a ±10% of R.O. adjustment range so a sensor with an
output close to one of the input ranges will work fine.
