Setup

Battery Installation

The MT75 requires one 9V battery (included). To install, open the battery compartment cover on the back of the device, insert the 9V battery, ensuring correct polarity, and then close the cover securely.

Initial Calibration

Before each use, it is recommended to calibrate the meter. Press the MEAS button to perform a quick calibration. This ensures optimal accuracy for your measurements.

Operating Instructions

Power On/Off

Press the Power button (⑂) to turn the device on. The meter will automatically shut off after a period of inactivity to save battery.

Mode Selection

The MT75 offers five distinct measurement modes for different material types. Press the MODE button to cycle through these options. Select the mode appropriate for the material you are testing to ensure accurate readings.

Reference (REF) Mode

The REF mode allows you to establish a baseline moisture level from a known dry area and then compare subsequent readings to this reference. This is particularly useful for identifying abnormal dampness in specific areas.

1. Locate a dry spot on the material you wish to test.
2. Place the meter on this dry spot and press the REF button to set this as your reference point.
3. Move the meter to other areas of the material. The display will show the current moisture level relative to your set reference.

This image illustrates the REF (Reference) function of the MT75 meter. It shows how to establish a baseline reading on a dry area (5.6%) and then compare it to a potentially damp area (19.6%) to identify moisture issues.

Hold Function

Press the HOLD button to freeze the current reading on the display. This is useful for taking measurements in hard-to-reach areas where direct viewing of the screen is difficult. Press HOLD again to release the reading.

Measurement Depth

The MT75 can detect moisture up to a depth of 40mm (1.57 inches) from the surface. This allows for comprehensive assessment of moisture content within materials without needing to penetrate them.

Proper Usage Guidelines

For accurate readings, ensure the sensor pad on the back of the meter is in full contact with the surface being tested. Avoid using the meter near metal objects, electrical wires, or water pipes, as these can interfere with the electromagnetic field used for detection and lead to inaccurate results.

Important usage guidance: This image warns against using the RDINSCOS MT75 moisture meter near metal objects, electrical wires, or water pipes, as these can interfere with accurate moisture detection.

Applications

The RDINSCOS MT75 is suitable for a wide range of applications, including:

• Woodworking: Checking moisture content in lumber, flooring, and furniture.
• Home Inspection: Detecting dampness in walls, ceilings, and floors in basements, bathrooms, and kitchens.

Maintenance

• Cleaning: Wipe the meter with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the meter in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the battery to prevent leakage.
• Battery Replacement: Replace the 9V battery when the low battery indicator appears on the display.

Troubleshooting

If you encounter issues with your RDINSCOS MT75 moisture meter, consider the following:

• Device does not power on: Check if the 9V battery is correctly installed and has sufficient charge. Replace the battery if necessary.
• Inaccurate readings: Ensure the sensor pad is in full contact with the surface. Recalibrate the meter by pressing the MEAS button. Avoid measuring near metal or electrical components.
• Display is dim or flickering: This may indicate a low battery. Replace the 9V battery.
