STANDARD SPAN & ZERO ADJUSTMENT:
Once all connections are complete you can begin to setup the
sensor/amplifier system. You will need to have the output from the
CSG110 connected to a device so you can readout the voltage or
current.
Apply a known load to the sensor.
sensor settled, use a screwdriver to adjust the output (i.e. 20mA, 10
VDC). If you are apply ng the full load to the sensor then you would i
want to adjust the CSG110 output to 10VDC or 20mA. If you are
apply ng half of the full load then you would want to adjust the CSG110 i
output to exactly half of the maximum. Once your span is set, check
the zero. With no load applied to the sensor, adjust the zero.
Adjusting the zero and span is done by using a screw driver to adjust
the pots.
SHUNT READINGS:
Shunt resistors simulate a load on the cell thus allow ng for calibration.
To simulate a load first determine the value of the resistor needed
( www.futek.com/shuntcalc.asp) . Connect the shunt resistor in the spot
labeled 'RSH'. When you would like to simulate the load to adjust the
span it is necessary to press the pushbutton that corresponds to the
shunt. While the shunt is enabled and the CSG110 is reading in the
simulated load adjust the span (described above) to the correct output
(pictured).

OUTPUT SELECTION:
To change the current output, solder the jumpers in the fashion
described in the table below:
mA Output
4-20mA (DEFAULT )
0-20mA
5-25m A
SELECTION OF INPUT RANGE & EXCITATION VOLTAGE:
There are two excitation values
available on the CSG110, 10
VDC
(default) and 5 VDC. To select
your excitation, simply connect
the corresponding jumper.
The input value range is from
0.5 to 4.0 mV/V. Select the
Input value closest to your input
range by soldering the
corresponding jumper.
For example: if you are using a 2mV/V sensor with the 5 VDC
excitation, then you would want to solder the 1.0 (10mV
you are using a 2mV/V sensor with 10 VDC excitation then you wou
want to solder the 2.0 (20mV jumper )
POLARITY REVERSAL:
The default polarity is
shown in the picture
on the left. To switch
the polarity, simply move
the jumpers to the
positions shown in the
picture on the right.
For example If you are using your CSG110 with a tension and :
compression load cell and you have tension setup as the positive
direction but woul d like to now have compression as the positive
direction all you have to do is move the jumpers from the 'Default'
polarity position to the 'Reverse Polarity' position.
