3. Opsætning
3.1 Batteriinstallation
The AMT65C requires a 9V 6F22 battery (not included). To install the battery:
- Find batterirummet på enheden.
- Åbn batterirummets dæksel.
- Insert a new 9V 6F22 battery, ensuring correct polarity.
- Luk batterirummets dæksel forsvarligt.
Note: Batteries are not included in the package due to aviation security regulations.
4. Betjeningsvejledning
Follow these steps for accurate moisture and temperature measurements:
- Forbered Sampdet: Unscrew the top cover of the meter. Fill the internal cup with the grain sample you wish to test. Ensure the grain is level and not overflowing.

Figure 4.1: Step 1 - Filling the grain cup. Shake gently to settle the grains, then screw the cover tightly.
- Power On and Select Grain: Screw the cover tightly onto the meter. Turn the meter ON using the "ON/OFF" key. Use the "MENU" and "Enter/Select" buttons to navigate and select the specific grain type you are testing from the list displayed on the LCD. Ensure the displayed grain type matches your sample.

- Tag måling: Press the "ON/OFF" key (labeled "Test" in some contexts) to initiate the measurement. Wait several seconds for the meter to process the sample. The display will show the moisture value and temperature.
- Repeat for Average (Optional): For more accurate results, press the "ON/OFF" key two times (first "OFF" then "ON" again) to repeat the test 2-3 times. Press the "MENU" key to view the average value. Press "MENU" again to erase or "ON/OFF" to exit.
4.1 Kalibrering
While the meter is factory calibrated, for optimal accuracy, especially when testing specific grain types or if you notice discrepancies, it is recommended to calibrate the device. This can be done using a known moisture content sample. Refer to the "Adjustment" option in the meter's menu for calibration procedures. For example, if calibrating for coffee, using a 12% humidity sample will provide the most reliable range of measurements around that value.
5. Vedligeholdelse
5.1 Rengøring
- After each use, empty the grain cup and gently brush away any residual grain particles.
- Wipe the exterior of the meter with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Ensure no moisture or debris enters the internal components of the device.
5.2 Opbevaring
- Opbevar måleren et køligt, tørt sted, væk fra direkte sollys og ekstreme temperaturer.
- Hvis produktet opbevares i længere tid, skal batteriet fjernes for at forhindre lækage.
- Utilize the provided carrying case for protection during storage and transport.

6. Fejlfinding
6.1 Almindelige problemer og løsninger
- Meter does not turn on or screen is full of dots:
This issue is often caused by a loose screen cable on the motherboard. To resolve:
- Fjern batteriet.
- Unscrew the cover (usually only one screw).
- Locate the screen cable connected to the motherboard.
- Using sharp tweezers, pull back the black clamp securing the cable.
- Carefully remove the cable, then reinsert it and tighten the clamp.
- Reinstall the battery and attempt to power on the device.
- "Put grain in meter and tighten" message persists:
Ensure the grain cup is properly filled and the top cover is screwed on tightly. The meter requires sufficient pressure from the cap to register the sample. If the issue persists, check for any obstructions or damage to the cap or sensor area.
- Unøjagtige aflæsninger:
Verify that the correct grain type is selected in the meter's menu. Ensure the grain sample is clean and free from foreign materials. Consider performing a calibration with a known moisture content sample for improved accuracy.
