8.4. Amplifier’s input properties
8.4.1. Input Sensitivity – Change this value if it doesn’t match the input sensitivity of the measuring
amplifier where the strain ages are connected to. Normally the value shown is the correct
value, some GSV-2 or GSV-4 measuring amplifiers do communicate the correct value to the
program. Together with the gauge factor, this value will be used to calculate the correct
scaling factor automatically after the OK button is pressed. NOTE: The strain gauges must be
wired in a quarter bridge configuration in order to calculate the scaling factor correctly.
8.4.2. Set Scaling factor – Uncheck this checkbox if you are sure that the scaling factors of the
channels where the three strain gauges are connected to are already correct. If checked, the
new scaling factor will be calculated automatically according to the gauge factors and the
input sensitivity settings. NOTE: the strain gauges must be wired in a quarter bridge
configuration in order to calculate the new scaling.
