• Type of calibration allows you to choose the type of calibration to use in the channel selected: A list of types of calibration appears when you click on the button with the left button of the mouse button. Make the choice based on the type of channel you are working on: e.g. for potentiometer sensors choose Linear The following types of calibration are available Type of calibration None Linear Description No calibration: The channel is not calibrated It is a linear type of channel and only the two values X and Y are needed to define the characteristic Step The channel provides a “stepped” signal: Up to ten levels can be defined Thermocouple Channel connected to a thermocouple probe: calibration is not required RPM Channel connected to the ignition pickup: Provide the X value based on your engine Speed Channel connected to the proximity sensor applied to the wheel * Time Time type channel: calibration is not required Latitude/Longitude Latitude and longitude GPS data channel calibration is not required Frequency Channel connected to a variable frequency channel: calibration is not required Accelerometer Channel connected to an accelerometer: calibration is not required NTC Channel connected to a NTC sensor: calibration is not required Voltage Channel connected to a voltage signal: calibration is not required Battery Voltage Channel connected to the battery voltage: calibration is not required RPM Spark Channel is connected to a rpm sensor on the spark plug cable: enter the Coeff and Offset values based on your engine GEAR Channel related to the gear ratio number entered: Enter the X (speed) and Y (rmp) values to identify the gear entered in the vehicle The value of speed varies according to the diameter of the tire used and the number of pulses per revolution sent by the sensor placed on the wheel. Use the Calc Diameter function for sensors placed on the pinion: a screen will open that will allow you to determine the values to enter to obtain a correct measurement of the speed • • Fields X, Y: Allows the association of the values read by the sensors (in the fields marked with X) to values set by the user (in the fields marked with Y). This combination of values defines that calibration of the channel. By clicking on an X field and then clicking the Capture button on the top right corner of the Calibration dialog box, the current value of the channel (Y field) is associated to the previously selected X field. WARNING: The direct acquisition procedure described above must be made with the GET data acquisition connected to a PC. If there is no data acquisition device connected to a computer you can enter the values in the X and Y fields manually using the keyboard. NOTE: consult the instruction booklet of the sensor being calibrated to know the XY values to enter in the appropriate fields The Show in volts option, if enabled, shows the voltage of the channel expressed in volts. 6.5.5 Applying an offset You can use the offset the button to specify a value to be added or subtracted to the value read from the selected channel. Use negative values to subtract the offset from the channel and positive values to add offset, confirm the data entered with the OK button.
