Product description

This product is a DC resistance type (pin type) material moisture meter, commonly used to measure the moisture content of wood or building materials. The moisture content of the material is displayed directly as a percentage. The instrument has built-in characteristic parameters of 7 different kinds of wood and building materials. This measurement can provide a basis for the need for further drying. In addition to measuring the moisture content of the material, the ambient humidity and temperature can also be measured so that the dry environment can be evaluated directly on site

Measurement operation

Attention
In order to ensure the accuracy of the measurement readings, please select as many points of average measurement as possible. Be Sure to measure moisture along the grain. The values shown are closely related to the building materials/manufacturers and the surrounding environment. Sometimes even for the same material, there will be great differences between different batches

Meter testing

Press the key to turn on the power and enter the measurement mode.
Press the key to select the measured material category as A, and the material category letter is displayedin the lower-left corner of the display.
After selecting the material category, remove the protective cap, insert two test pins of the instrument into the test contacts on the protective cap at the same time, and ensure good contact.
Press the key to hold the measurement result and the symbol.”H” is displayed on the LCD screen.
Read the measurement result from the display.
When the measurement is finished, please put the protective cap on in time.

Other operations

Auto shut down
Without any operation, the meter will automatically shut down after about 10 minutes to save battery energy. If necessary, you can cancel the automatic shutdown function as follows:: Press and hold the key, and then turn on the power. The automatic power off will be canceled, and the symbol will be hidden. so the user needs to turn the power off manually.

Maximum and minimum measurement
Press to turn on the function of maximum and minimum values, and then press this key to view the maximum and minimum values in cycles; press and hold for about 2 seconds to exit the function of maximum and minimum values.
