Calibration for single and multiple measurements (laboratory)
O Note: For optimum calibration results, see the calibration tips on page 29.
1. Turn on the device if it is not already turned on. The switch is on the back of the device.
If the device is already in operation, stop the current measurements.
2. Select the Calibration menu item.
3. Now select the Product choice menu item.
Protected products are indicated by a lock. You cannot alter the calibration of a protected product.
4. Select the required product in the Product choice dialog and click Apply.
5. In the Calibration menu, select Moisture calibration or Density calibration.
6. We recommend that you use the table view (default setting) to clearly display the measured cal-
ibration values. If this view is not already set, choose Table to switch to the table view.
O Note: If calibration data already exists for the selected product, the system displays it now.
7. Press Start.
8. If there is still a product in the sensor, the system issues a Please empty! prompt.
Remove the product or insert an empty measuring cup (depending on the sensor used).
The system issues an Empty sensor adjust... message.
The device tells you that it has detected an empty sensor.
O Note: If you are asked to empty the sensor when it is already empty, press the ES (empty
sensor) adjust control.
This tells the sensor that it is empty – the system then compensates for changes that may have
taken place on the sensor, such as the accumulation of dirt or thermal changes.
9. The system issues a Please fill! message.
Fill the sensor.
If a sensor with a measuring cup is used, ensure that it is completely filled. When filling the meas-
uring cup, make sure that there are no large cavities.
If a planar sensor is being used, ensure that the sensor is evenly covered with the product.
10. Optional: Insert the PT 100 temperature sensor into the sample.
The measurement is carried out by the device.
In the case of simultaneous temperature measurement, the measurement is taken once a con-
stant temperature value is recorded.
O Note: When a reference value is measured, both the moisture and the density are recorded.
However, calibration is carried out separately for the two measurement parameters.
11. Depending on the sensor used and the system settings, you are asked to rotate the sample or to
place a new sample into the sensor. Then repeat steps 8 to 10.
12. Press Save.
13. The dialog for entering a remark is shown. You can enter the number of the sample here, for
example. Then press Apply.
