The "User Scaling" window is used to configure the measured value display.
In this dialog, two different methods are offered for general sensors in order to adjust the measured values for specific sensor specimens. There is a third method for individual strain gauges.
1. With the "Sensor data" input mask, the display is configured based on the technical data of the sensor from the test report or from the calibration certificate. The following data is needed:
• Nominal measuring range (Physical full scale)
• Electrical full scale output
• Eventually: Input Range of the amplifier
2. With the "Calibration" input mask, the scaling factor can be determined using a known reference load. To do this, it must be possible to free the sensor from the payload to be measured and then to apply the reference load. This procedure corresponds to a 2-point calibration, in which the first point is set to zero by the measuring amplifier, so that the characteristic curve is shifted parallel to the y-intercept =0.
The input measuring range is known to the software for most GSV models, since it is read out from the measuring amplifier. Most often it is 1, 2 or 3.5 mV/V. With the GSV1A8 measuring amplifier and possibly also with the GSV-3, you must enter the input sensitivity (i.e. the electrical measuring range) under "Input Range" for all three methods. It's usually specified on the type plate.
Calculate calculates the scaling factor to be programmed.
It is permanently stored in the measuring amplifier with OK/Set.
The unit to be displayed can be set in the Configuration tab, or under Menu Bar->Channel->Unit.
Some multi-dimensional sensors like K6D, F6D and K3R are not configured here but in the "Special Sensors" dialog.
