4.3 Category Setup

Create a new grain in category. Prepare the samples of this new category with

3 or 4 different moisture content levels (for example, prepare 15%, 20% and

25% moisture levels of a new grain.)

Note: Check the Moisture level of the sample with a Moisture Balance (e.g.

MB45) and then compare the result with the MC2000. Adjust any differences

of the result.

1. Press button, enter category mode.

2. Press or button to select desired category code to setup.

3. Long press button until display shows “-1-”, the instrument is in the

setup mode.

4. Fill the sample with lowest moisture content level (for example: 15%) in

the container. Press "release" button on the container and the result will

be displayed. If the result is different from 15%, press and

buttons to adjust the moisture result to 15%. Press button to save

the result and the instrument will show “-2-”.

information about the measurement process.

2. The test order to build up a new category is from low

moisture level standard sample to high level (for example

test 15% level sample first, then 20% and then 25%...).

3. We recommend the difference of moisture level between

each standard sample to be around 5%. And the whole

moisture range of these standard samples should be within

the real object range (for example 15%, 20% and 25%).

5. FACTORY RESET

1. Enter category mode.
