3. Setup

3.1. Power Supply

The EVTSCAN Grain Moisture Meter can be powered by two methods:

Battery Power: Insert 4 x AA dry batteries (not included) into the battery compartment located on the underside of the unit. Ensure correct polarity. This method is convenient for outdoor use.
AC Power: Connect the provided US Plug 100-240V power cord to the AC input port on the side of the unit and plug it into a suitable power outlet. This method is convenient for indoor use.

Note: The two power supply methods cannot be used simultaneously. Disconnect the AC adapter when using battery power, and remove batteries if storing the unit for extended periods or when using AC power.

4. Operating Instructions

4.1. Powering On/Off

To power on the device, simply touch the "ON/OFF" button on the control panel. The smart chip technology allows for a touch-to-start operation without requiring a hard press. To power off, touch the "ON/OFF" button again. The device features an intelligent sleep function to conserve power during periods of inactivity.

4.2. Selecting Grain Type

Press the "Species" button to cycle through the 24 available grain types. Use the up and down arrow buttons to navigate and select the specific grain you are testing (e.g., Corn, Paddy, Wheat). The selected grain type will be displayed on the LCD screen.

4.3. Taking a Measurement

Ensure the device is on and the correct grain type is selected.
Carefully pour the grain sample into the funnel at the top of the unit. Use the scraper funnel and sampling tube to ensure a consistent and appropriate sample volume.
The device will automatically weigh the sample and initiate the measurement process.
Within approximately 2 seconds, the moisture content percentage and temperature will be displayed on the LCD screen.
Press the "OK" button to confirm or proceed.

4.4. Temperature Display

The device can display the grain temperature in either degrees Celsius (°C) or Fahrenheit (°F). Refer to the on-screen indicators or specific menu options (if available) to switch between these units.

4.5. Advanced Functions

Average Moisture Content: The meter automatically calculates and displays the average moisture content over multiple readings, providing a more representative result.
Capacity Conversion: The device can perform capacity conversions, which may be useful for specific agricultural applications.
Multi-point Calibration: For enhanced accuracy, the meter supports multi-point calibration. Consult the device's on-screen menu or specific instructions for performing calibration if required.

5. Maintenance

5.1. Cleaning

After each use, especially when testing different grain types, use the provided cleaning brush to remove any residual grain particles from the funnel, sampling chamber, and sensor area. This prevents cross-contamination and ensures accurate readings. Do not use abrasive cleaners or immerse the unit in water.

5.2. Storage

Store the EVTSCAN Grain Moisture Meter in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, remove the AA batteries to prevent leakage.

6. Troubleshooting

Problem	Possible Cause	Solution
Device does not power on.	Batteries are depleted or incorrectly inserted. AC adapter is not properly connected or faulty.	Replace AA batteries, ensuring correct polarity. Check AC adapter connection and power outlet. Try a different outlet or adapter if available.
Inaccurate or inconsistent readings.	Incorrect grain type selected. Sensor or sampling chamber is dirty. Sample volume is inconsistent. Device requires calibration.	Verify the selected grain type matches the sample. Clean the sensor and sampling chamber thoroughly with the provided brush. Ensure consistent sample volume using the scraper funnel. Perform multi-point calibration as per advanced functions.
LCD display is dim or blank.	Low battery power. Device in intelligent sleep mode.	Replace batteries or connect to AC power. Touch the "ON/OFF" button to wake the device.
