3.8 | Shunt Calibration
1. An electrical signal equivalent to that produced by a known
load can be obtained by activating the Shunt Calibration
function.
The Shunt Calibration function is achieved by connecting
a high-precision resistor of known value, in parallel (shunt)
with one arm of the strain gage Wheatstone bridge. The
connection is made by a solid-state switch, which will be
activated by the Shunt Cal ON button.
In the Summing In-Line Amplifier, a fixed resistor with resistance of 61900 Ohms is used as the shunt resistor. The
output of the Summing In-Line Amplifier during Shunt Cal
ON depends on the bridge resistance and sensitivity of the
sensor connected to the amplifier.
When a Sensor with the 350 Ohm Bridge resistance and
2.0mV/V sensitivity is connected to the amplifier, the
output of the amplifier will saturate to ~70% of full scale
during the shunt calibration.
Table 3.8a. Shunt calibration Output vs Bridge resistance & Sensitivity
008-0749-00
Figure 3.8a. Shunt Cal ON Option
1. Observe the output.

2 350 4 35%
3 350 10 14%
4 700 10 28.2%
Shunt Cal On Output = (0.000004286* Bridge Resistance) *100
(Sensitivity)
Example:
Consider Sensor with Bridge resistance of 700 Ohm & Sensitivity 10mV/V
Shunt Cal On Output = 0.000004286 * 700*100 = 28.2% of Full Scale = 2.82V

Output of the Summing In-Line Amplifier under shunt
calibration for any other values of the bridge resistance and
sensitivity can be calculated using this equation:

4 | WARNING & ERROR MESSAGES
4.1 | Output Scaling
The Sensitivity should be within the Range of 1.5mV/V -12mV/
V. The user interface will pop up a warning when it is out of
range
Figure 4.1. Sensivity Out of Range
008-0749-00
4.2 | Taring with More Than 30 % Load
The amplifier will allow Taring off 30 % of FS preload of the
system.
Taring off with more than 30 % delivers an error message.
Here is an example.
Figure 4.2a. Tare Weight Limit Crossed
• If the entered value is more than 12, a default value of 12
mV/V will be used.
• If the entered value is less than 1.5, a default value of 1.5
mV/V will be used.
Similarily, the Value of Zero output should be within the range
of ± 10 % FSS.
Because the example shows 50 % of load applied, the device
would pop up a warning message.

5 | DIAGNOSTIC FEATURES
The amplifier’s sensor LED indicators glow red or green depending on whether a sensor is connected to the amplifier port.
Under normal operating conditions with four sensors connected to the amplifier, all four LEDs will glow green.
1. When sensors are not conencted to an amplifier port, the
LED for that port will glow red instead of green. Likewise
when the amplifier is connected to a PC/laptop with the
desktop application running, the sensor displays will also
glow green or red.
Figure 5. Sensor LED and Desktop Interface
In this example you see that sensors 3 and 4 are not
connected and glowing red on the amplifier and the user
interface.
2. A red indicator can also mean the sensor is faulty, a bridge
is open, or shorted out.
3. A red indicator also indicates a sensor is loaded more than
110 % of FS.
Example: When the load on an individual sensor is more
than 110 % of FS, the LED will blink red to indicate potential overload of the sensor.
