操作說明
電源開/關
按 力量 button (⑂) to turn the device on. The meter will automatically shut off after a period of inactivity to save battery.
模式選擇
The MT75 offers five distinct measurement modes for different material types. Press the 模式 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.
- Locate a dry spot on the material you wish to test.
- Place the meter on this dry spot and press the 參考文獻 button to set this as your reference point.
- Move the meter to other areas of the material. The display will show the current moisture level relative to your set reference.
