Use of the wood moisture meter and safety measures
How to use wood moisture meter and precautions, wood moisture meter may be split into pin type wood moisture meter and induction wood moisture meter.
How to use the wood moisture meter:
1. Gear setting method: first press the gear setting button (SPECIES), and then press the test button (TEST), at this time the current gear value is displayed, press the setting button continually, and the gear may be continuously modified until needed stalling.
2. Verify before measuring: Set the instrument to level 5 using the aforementioned method, remove the cap, touch the instrument's probe to the two contacts on the cap, and press the test key. If the display reads 181, the instrument is in good condition.
3 Measurement: Insert the probe on the instrument into the wood specimen to be measured. When you press the test button, the instrument will display the average moisture content of the test piece. If the test piece's water content is below 3, it will show 3.0, and if it is above 40, it will show 40, indicating that it is outside the acceptable range.
Precautions for wood moisture meter: 1. When using the instrument for the first time, you can change the gear measurement according to the empirical range value of wood moisture, which gear has the smallest error, and then measure it in this gear.
2. If the wood moisture to be measured is unknown, the gear can be determined as follows:
First take a wood sample with relatively average moisture content, measure the moisture content with the instrument at levels 1-7, and record the measured values of each level. Then the samples were sent into the oven, and the moisture content was determined by the oven drying method. Then compare it with the average value of 7 groups, which gear has the closest value, and then fix it at this gear. If the above measurement is unconditional, it is usually recommended to perform the measurement on the 5th gear. However, attention should be paid to the measurement error caused by this.
