Standard Span & Zero Adjustment
Once all of the connections are complete, you can begin to set up the sensor/amplifier
system. You will need to have the output from the CSG110 connected to a device so
you can read the voltage or current.
To set up the system, follow the steps below:
1. Apply a known load to the sensor.
2. Allow the sensor to settle.
3. Use a screwdriver to adjust the span that correlates with that load.
4. Remove the load.
5. Allow the sensor to settle.
6. Adjust the zero.
Ex. If you are applying a full load to the sensor with an excitation voltage of 10 VDC,
then you would want to adjust the output (span) to 10VDC or 20mA. If you are
applying half of the full load then you would want to adjust the span to exactly half of
the maximum. Once your span is set, check the zero. With no load applied to the
sensor, adjust the zero.
Note: Adjusting the zero and span is done by using a screw driver to adjust the
potentiometers (pots).

Shunt Readings
Shunt resistors simulate a load on the load cell; thus, allowing for calibration. Follow
the steps below in order to utilize the shunt feature.
1. Determine the value of the shunt resistor needed
(http://www.futek.com/shuntcalc.aspx)
2. Connect the shunt resistor in the spot labeled ‘RSH’.
3. Press the pushbutton that corresponds to the shunt.
4. While the shunt is enabled and the CSG110 is reading the simulated load, adjust
the span (described above) to the correct output.
Ex. If you are using a 2 mV/V sensor with a 350 Ohm bridge and the default 60.4 kOhm
resistor on the CSG110, then the simulated load would be approximately 72% of R.O.
You can then adjust the span to 7.2 VDC to correlate with this simulated load.
Switch Configurations
To change any of the switch configurations from the default settings, follow the tables
below to set your desired configuration. The figure below shows the default
configuration.

SW1: Excitation (VDC)
Excitation
There are two excitation values available on the CSG110: 10 VDC (default), and 5 VDC.
To select the excitation, simply flip the DIP switch to the appropriate configuration.
The excitation voltage controls the maximum output of the amplifier.
Ex. If your application requires a lower output voltage than 10 VDC, then the 5 VDC
option is available to use. All you have to do is flip the DIP switch from the down
position to the up position.
Polarity
There are two polarities available on the CSG110: reverse, and straight (default). To
select the polarity, simply flip the DIP switch to the appropriate configuration.

SW2: Polarity
Ex. If you are using your CSG110 with a tension and compression load cell and you
have tension setup as the positive direction, but now you would like to have
compression as the positive direction, all you have to do is flip the DIP switch from the
default polarity position to the reverse polarity position.
Gain
There are eight gain settings available on the CSG110: from 0.5 mV/V to 10 mV/V. The
default setting is configured to 2 mV/V. Select the value closest to your input range by
flipping the DIP switches to the appropriate configuration.
Ex. If you are using a 2 mV/V sensor with the 5 VDC excitation, then you would want to
use configuration 2 for 1 mV/V. If you are using a 2mV/V sensor with 10 VDC
excitation then you would want to use configuration 4 for 2 mV/V.

Bandwidth
There are two bandwidth settings available on the CSG110: 1 kHz (default), and 10 kHz.
To select the bandwidth, simply flip the DIP switch to the appropriate configuration.
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 CSG110: 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.
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 CSG110
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 CSG110 has a ±10% of R.O. adjustment range
so a sensor with an output close to one of the input ranges will work fine.
