II. Preparations before Use

1. Take out protective foam blocks filled around the measurement sensor of the moisture meter ( “the

meter” for short), and meanwhile confirm that the sensor is free of any substance, otherwise the meter

will not work properly;

2. Open the cover of battery compartment at the bottom of the meter, load in four 5# alkaline (1.5V)

dry batteries (rechargeable batteries must not be used) according to polarity indication, or plug into AC

power source (200V±10%, 50Hz) with AC adapter which is provided together with the meter;

3. Put the meter on a wind-free and shake-proof horizontal platform and make the funnel closely

attached to sample container.

4. Get ready the sample to de tested: conduct preliminary sample screening, get rid of impurities, and

put the sample in the meter for as long as possible to achieve temperature balance;

5. Check the list to identify category code: for ease of operation, the calibration parameters for

representative categories have been preset during shipment of the meter. During application, all you

need to do is check the “category-code list” attached to this User’s Manual and chooses the

corresponding category code for moisture measurement.

Note: when the meter is used for trade settlement and safe storage which needs higher precision, we

strongly recommend that you adopt standard sample of the category to be measured and conduct

calibration and error correction of the meter so as to ensure measuring precision and safeguard your

interest.

III. Moisture Measurement

1. Press down the power switch and the meter starts self-check. If no abnormality is found, the category

code will be displayed;

Note 测量：measure

2. Press the “ ” or “ ” key to choose the code of category to be measured (refer to the attached list △▽

for details);

3. Put the sample into the blanking cylinder to the lower edge of funnel for later use (see Figure A);

4. Make the blanking cylinder closely attached to the meter’s sensor, support the blanking cylinder with

one hand and press gently the switch for discharge gate (shown in Figure B) to make the sample fully

and evenly fall into the measuring sensor. Without pressing any key, the meter will automatically start

the measurement and the moisture value will be displayed after the decimal point flickers several times;
