3.Panel description:
4.Nine groups of materials (wood)
5.Measurement procedures
If the test pin is not fitted to the probe tip, press Figure installed.

5-1Select the material group to measure
1) Press“Power”Key to power, remove the rubber protective cover on the probe
2) Use“Material”Keys to select the group of materials to be measured
According to4-1, The table1From the materials group (1-9), Select the appropriate materials
*Select the firstposite panels9Group
*General timber, select the first1-9Group
*Do not know in the case of materials like paper, pigments, etc., in the light5-2The steps
For example:
European linden wood selection“4”Synthesis board selection“9”
3Minimum depth) in the test, the probe is inserted into the material is2mm. If the probe is inserted into the depth can not be achieved2mm, You should probe into the material can reach the maximum depth of
4) Moisture content will have a direct way to show the percentage of
*If the moisture content of the analyte is high, it may take a few minutes, the readings to stabilize
*Moisture content is greater than30%Will be displayed“ ---- ”Moisture content of less than9%Will be displayed“----”.
5-2 Reference measurement method
For1-9Materials, outside the group can use the following method, the measured values in this table as a reference
1) Press“Power”Key to power
2) Select the material group1
3) The probe is inserted into the material being tested
4) Reference moisture content is displayed on the table as a percentage
Note:
Measurement of moisture content only as a reference.
Although the measurement data is only as a reference, but you can use this data to estimate the humidity of the tested materials, to the measurement table1Materials not listed in the moisture content, this method is very useful.
5-3 Adjustment of the temperaturepensation
The initial temperature of the moisture tester is set to20/68. Meter readingspensation is this: In20 below5 plus0.5%In20 above, each5 minus0.5%
If the ambient temperature is not20° C, while the reading is accurate, please follow these steps:
PressTEMPOrADJKey, so thatLCDDisplay the initial temperature20. PressTEMP ADJButton to adjust the temperature, the left-plus right-minus, each time you press to change1. To the desired temperature, wait for about4Seconds, the instrument will automatically return to the measuring state.
Note:
Shutdown temperaturepensation adjustment mode, the new temperature setting will be invalid, the initial temperature will return to the default20
