Pinless Moisture Meter MT-28 User Manual
This document provides a comprehensive guide to the Pinless Moisture Meter, model MT-28. It covers essential safety instructions, product specifications, operational procedures, and maintenance guidelines.
The MT-28 is designed for the non-destructive determination of moisture content in various materials, including wood and building materials like drywall and masonry. It operates on the principle of dielectric permittivity, offering accurate readings displayed in percentage (%) relative to the dry mass of the material.
Key features include multiple measurement modes for different material types (Wall, Masonry, Soft Wood, Hard Wood), a clear 2.6-inch LCD display with indicators for moisture levels (Dry, Mid, Wet) and battery status, and a built-in flashlight for low-light conditions. The device also features a data hold function and automatic shut-off after 5 minutes of inactivity to conserve battery life.
Users are advised to read all safety warnings carefully before operating the device. Important precautions include avoiding use in potentially explosive environments, protecting the device from liquids and corrosive chemicals, and ensuring proper handling to prevent damage or inaccurate readings. The manual also details the process for inserting and replacing the 9V battery, selecting measurement modes, and performing zero calibration.
For optimal performance, it is recommended to ensure the material surface is dry and clean, and to avoid measuring materials with temperatures below -5°C or those affected by static electricity or electrically conducting substances. The device's measurement depth is up to 19mm (0.75 inches), and readings can be influenced by nearby metal objects or the user's touch. Always measure at multiple spots for the most reliable results.
