Solitrend MMP20 (Option D)

S1 moisture probe

Hauser

higher-value polynomial is useful to achieve better accuracy, the linear equation often

suffices, particularly in the lower moisture range, and delivers very good results.

Two material samples with different moisture values are required to perform a 2-

point material calibration. The moisture values must be determined with another

laboratory method (e.g. moisture analyzer, kiln drying) before the calibration. It is

important to adhere to the following sequence: first "lower moisture value" (drier

material) and then "upper moisture value" (wetter material).

1. Set the calibration memory (01 – 15) to be overwritten value using the navigation

keys


2. Press the Enter key

 The setting is accepted

3. Select the percentage moisture of the lower moisture value using the navigation keys



4. Press the Enter key

 The setting is accepted

5. Press the Enter key again

 The material measurement process is started

Four measurements are taken in order to increase the accuracy. An average of

these measurement values is then calculated. The measuring time is

approximately 20 seconds. When the measurement is finished, the measured

pulse transit time is displayed briefly.

6. Select the percentage moisture of the upper moisture value using the navigation keys

7. Press the Enter key
