8.1 Taking measurements in the laboratory
O Note: Device messages are displayed in the status line.
For more information on the touchscreen and how to use it, see Operator Interface - Reference
(Details on page 65).
1. Turn on the device if it is not already turned on. The switch is on the back of the device.
Recommendation: After switching on the device, wait a few minutes before taking the first meas-
urements, since this allows the device to reach its optimum operating temperature.
O Note: If the device is already switched on, a different area of the software may be active, e.g. the
Product settings dialog. If this is the case, select the Measurement menu item.
The LMA321PA automatically starts with the product which was measured last. If you intend to
measure a different product, you are required to specify this product first (proceed with step 5 if
the desired product was already selected):
2. Press the product name. The Product choice (Details on page 73) dialog appears.
3. In the table, select the row containing the product for which you want to take measurements.
4. Press Apply.
5. Press Start.
6. 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).
The device briefly displays Empty sensor adjust followed by Fill sensor!
O Note: If you are asked to empty the sensor when it is already empty, press the ES adjust (empty
sensor adjust) control and then choose Hard.
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.
You may have to log in again with a user with appropriate user rights to carry out the empty sensor
adjust (see page 30).
7. 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.
8. Optional: Feed the PT 100 temperature sensor into the sample.
O Note: As a rule, the temperature should be taken into account for the calibration if there are
temperature variations of more than ±5°C.
9. 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.
10. Save the result by pressing the Save control.
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. Carry out steps 6 to 10 until you are asked by the device to
enter a remark.
