Ex. If your application requires a higher bandwidth in order to account for the higher
frequency signals, such as those from dynamic applications, then you would want to
use the higher setting bandwidth.
Current Setting (4)
There are four current output settings available on the DCM 470: 0-16 mA, 0-20 mA, 4-
20mA (default), and 5-25 mA. To select the current, simply flip the DIP switches to the
appropriate configuration.
Note: Only available with current output option.

Advanced Span and Zero Adjustment
Adjusting the Zero
At times, when using a signal conditioner, it is necessary to offset the zero. The DCM
470 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 DCM 470 has a ±10% of R.O. adjustment range
so a sensor with an output close to one of the input ranges will work fine.
