4.1 Cautions

1.Choose the right mode before measurement. 2.When measuring building materials under scanning mode, be sure to dling tothe target object It highiy recommended to test under prod mode.
area of wood moisture meter. 4.In scanning mode hold the two ends of the device when measuring. Do ot touchits sensing area. 5. Select the right measuring mode. For example,is incorrect to testa softwood using hardwood measuring mode. 6. Rest the unt for at least 15 minutes before measurement when changing the surroundings from indoors to outdoors or vice versa. 7.1 the prod mode, the meter willalarm and no readings will be displayed ifthe target object is too dry or too wet to exceed the set imit, 8.When testing plaster under prod mode, make sure the two are in good contact,

4.2Install the battery

Open the battery cover, and correctly instal the batteries according to indication on the battery cover.

4.3 Scan to measure moisture content

Select the corresponding scanning measurement mode according to the. properties of objects to be tested (., chaose the MASONRY mode to test the concrete wall. Please keep the probe cover closed during measurement, and the LCD screen displays the corresponding measuring mode. At this time, place the bottom of instrument o the surface of the object to be tested, then its moisture content will be displayed on the screen. Keep the instrument stilland short press the button 3¢ to lock the current measurement value. You can remove the device and record the value now. Short press the button 3# again to unlock the data for continuing measurement or shutdown.

4.4 Use the prod to measure the moisture content
4.1 Pres the button 24 or 4 to seect the wood mosture measuring mode, then the () symbol isdisplayed on the screen. Open the probe  cover,stab the probes into the wood, and the wood moisture data can be displayed on the screen. Short press the button 3¢ to lock the data. Remove the device and record the data. Press the button 3# again to unlock the value and continue to measue the other objects.
442 Use the same way to measure building material. et the device enter building materials measuring mode by press the button 24 or 4f, and stab the probes nto the materials to get the value. Short press button 34 to lock the data and record the value. Short press the button 3# again to unlock and continue to measure others.
443 To measure the ambient temperature, press the button 26 or button 4# to enter amblent measuring mode. The instrument automatically detects the temperature of the current environment.

5. Notes
» Keep the instrument dry. » Keep the probes dry and clean. P Keep the instrument away from children’s reach. > Some factors such as the type and temperature of materials, an affect the moisture measuring results. The measuring value of this instrument s only for reference

6. Technical Interpretation

6.1 How many methods are there for measurement of moisture content rate?
‘There are drying method, electrometric method, dry distllation method, titration method, and moisture method. Drying method and electrometric method are normally used n the production test.
Asfor the drying method, the moisture content ratio s obtained by measuring the difference of moisture content of timber specimen before and after drying (absolutely dry). Having a high accuracy and being time-consuming and tedious, it is usually used in laboratories
Inthe electrometric method, the misture content ratio is measured according to some electrical properties of timber.It i quick and convenient but less accurate than that of drying method, which can meet the production process requirements and is applicable to manufacturing of timber and bamboo products on a arge scale.

6.2 What is the difference between inductive and prob moisture meters?

‘The electrometric method is mainly divided into DC resistance type (probe type) and AC dielectric type (inductive type)
s for the probe type, a probe is inserted into the inner layer of timber to measure the resistance between the two electrodes, which can be affected by factors lke tree species,texture direction, temperature and insertion depth. Normally, the displayed data is smaller in the horizontal direction than in the texture direction, and production testis often based on horizontal direction. The density of tree types does not influence moisture content to a great extent. For instance, Chinese fir a softwood) and oak (a hardwood) differ greatly with respect to density, but equilibrium moisture contents are about the same. The advantage of probe typeis quick response, strong anti- interference, and high accuracy.
Inductive type i the AC dielectric type. Such meters adopt tabular electrodes or punch electrodes. During measurement, the polar plate clings to the timber surface. Such meters allow quick and easy operation, but their measurement accuracy is not as good as that of probe type.

One ofits important advantages i that it does not cause damage o the. surface of timbers. If you want to measure valuable wooden furiture or valuable wood, or don’t want to leave measurement marks on a smooth wall, and your accuracy requirements are not very high, this measurement method is highly recommended.
Due to the different measurement area and depth between probe type and inductive type (the maximum depth of inductive type is 20mm while. the probe type depends on the insertion depth), we won’t suggest you to determine their accuracy by comparing the test data. Please select the suitable way according to your actual requirements.

6.3 What is the difference between softwood and hardwood?

Generally speaking, softwood, the coniferous timber, is made of cypress plants including pine, spruce, cedar, fir larch, Douglas fir, hemlock, cypress, California rosewood, yew, etc.
Hardwood refers to those fine and hard timbers, mainly including deciduous. fine-leaf trees,including oak, mahogany, birch, red oak, hard maple, red birch, beech, and boxwood.
Since there are so many kinds of tree species, they cannot be listed one by one.Ifthere is anything rough, please kindly understand us.
