4. Setup

4.1 Battery Installation

The Elitech MOT-270W requires one (1) AAA battery (not included) for operation. Follow these steps to install the battery:

1. Locate the battery compartment cover on the back of the device.
2. Slide or unclip the cover to open the compartment.
3. Insert one AAA battery, ensuring the correct polarity (+/-) as indicated inside the compartment.
4. Replace the battery compartment cover, ensuring it is securely closed.

4.2 Initial Power On

After installing the battery, press the Power button to turn on the device. The LCD display will illuminate, and the meter will perform a brief self-test before entering measurement mode.

5. Operating Instructions

5.1 Taking a Measurement

1. Remove the protective cap from the measurement pins.
2. Select the appropriate material mode (see Section 5.2).
3. Firmly press the two measurement pins into the material you wish to test. Ensure both pins penetrate the surface to obtain an accurate reading.
4. The moisture content percentage will be displayed on the LCD.
5. For materials where readings might fluctuate quickly, consider using the Data Hold or MAX/MIN functions (see Section 5.3).
6. After measurement, carefully withdraw the pins and replace the protective cap.

5.2 Material Modes (Measurement Gears)

The MOT-270W features multiple measurement modes, sometimes referred to as "gears," to provide accurate readings for different materials. Press the M button to cycle through the available modes.

Figure 3: Material modes (gears) for various wood types and construction materials.

The modes are categorized as follows:

Select the mode that best matches the material you are testing for the most accurate results. If your specific wood type is not listed, choose the grade that corresponds to a similar density or common usage (e.g., Grade 3 is often suitable for many common woods).

5.3 Data Functions

5.3.1 Data Hold Function

The Data Hold function allows you to freeze the current measurement on the display, which is useful when taking readings in hard-to-reach areas or when the value is fluctuating.

1. While taking a measurement, press the HOLD button. The current reading will be held on the display.
2. Press the HOLD button again to release the hold and resume live measurement.

5.3.2 MAX/MIN Value Tracking

This function allows you to track the maximum and minimum moisture content detected during a measurement session.

1. Press the SET button to activate MAX/MIN mode. The display will show "MAX" or "MIN".
2. As you take measurements, the display will update to show the highest (MAX) or lowest (MIN) value recorded.
3. Press the SET button again to switch between MAX and MIN display.
4. To exit MAX/MIN mode, press and hold the SET button.

6. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Probe Care: Keep the measurement pins clean and free of debris. Always replace the protective cap when not in use to prevent damage to the pins and accidental injury.
• Storage: Store the meter in a dry, cool place, away from direct sunlight and extreme temperatures. Remove the battery if storing for extended periods.
• Battery Replacement: Replace the AAA battery when the low battery indicator appears on the display to ensure accurate readings.
