6.2.3.2
Two-point calibration
In the two-point calibration option, only the maximum and minimum points are selected. For
example; When calibrating a 10 cm linear potentiometer, the potentiometer is set to the
minimum point in the fully closed position, while the potentiometer is fully open.
6.2.3.3
Multi (segmented) calibration
With the multiple calibration option, you can calibrate your device at up to 10 different
points. This method increases the linearity of the sensor.
For example; If the length of the sensor is 40 cm and you want to calibrate at 5 different
points, these points are; There may be 0. cm, 10. cm, 20 cm, 30 cm, and 40 cm points where
the sensor ends. These points can be set anywhere in the scale range. We recommend that
you choose equal intervals for a more suitable linearity.
6.2.3.3.1
Number of Calibration (CL.CNT)
In this menu, which appears when you select the segmented calibration option, you can
specify the number of points you want to calibrate the device. It's a maximum of 10.
6.2.4
Automatic Calibration
From this menu, you can start automatic calibration by pressing the PRG key according to
the calibration method you selected in section 6.2.3.
∙
If you have set the calibration method to Two Point Calibration, press the PRG key and
CAL-L will blink while the sensor is at the minimum point. Press the PRG key to set the CAL-L
value. After this, the CAL-HI indicator will blink while you move your sensor to the maximum
point. Press the PRG key to set the CAL-HI value.
∙
If you have set the calibration method to Multi Calibration. During calibration; You can see
the calibration point you will set on the first line with the flashing segment number and on
the second line the unprocessed value read on the sensor. You can select the segment with
the up and down arrow keys. You can confirm the segment you want to specify with the PRG
key while the sensor is in position for calibration. DONE will appear on the screen for a very
short period of time.
Note: During calibration the unprocessed value read from the sensor appears on the second
line of the display. Do not confuse this value with a scale value.
6.2.5
Error Message
This error message can only be seen on devices with
4-20mA and 0.5-4.5V inputs. Meaning; The sensor is not
connected to the device or the sensor is defective.
