Mastfuyi FY886 Digital Wood Moisture Meter a. Practical design. Slim appearance, easy to carry, with striped non-slip soft rubber at the handshake, it is convenient and comfortable to use. b. Rich measurement mode. This moisture meter not only has a wide measurement range, it can measure wood and building materials, and it divides the measurement materials into 7 categories , this design makes the measurement more accurate. c. Check and calibration function. After using for a period of time, most of the instrument products will have a decrease in accuracy and data deviation. Generally, you need to re-purchase similar products at this time. However, we have designed a calibration board on this product, users can check whether the accuracy of the product is normal at any time, and can also calibrate by themselves when the accuracy is abnormal, which can greatly extend the service life of the product and save the cost. d. Replaceable test pin design. Usually, the probe will bend after a period of use, which will affect the accuracy of measurement and the sustainability of detection. And if you have to discard the entire product just because of the probe problem, we think this is a huge waste and not environmentally friendly. Therefore, we have made a replaceable test pin design on our products. When the test pin is bent, you can take it out and install a new test pin. The installation proce is very simple and rapid. Each of our products will be equipped with an additional pair of probes, if you are still not enough after a period of use, please feel free to contact us, we will provide you with a replacement for free. e. Ambient temperature measurement function. On this product, we have also added the ambient temperature measurement function. One product integrates two uses. When you just need to know the temperature of the air, you don't need to find another temperature measuring instrument. It is enough to use this product. And the temperature unit can also be switched.(/) f. Data freeze. When detecting a target, we need to firmly insert the probe on the target, but it will inevitably be loosened, which will cause the value to change. When this happens, just pre the ''HOLD'' key lightly, and the measured value will freeze on the screen regardle of the change of the probe and the target, which is convenient for data recording. g. High-definition backlit display. You can turn on the backlight when the light is low, and turn off the backlight when the light is bright to save power. h. Automatic shutdown on and off. When the product is used, it often forgets to shut down, resulting in exhaustion of power. On this product, we have designed a 10-minute no-operation automatic shutdown function to reduce unneceary waste of power. And if you need to use it for a long time, you can turn off this function.

Place the probe tips on the surface carefully, do not apply force. If the probe has been bent, replace it with two new replacementtest pins (included) by rotating. b. Handle the device carefully when the protective cap has beenremoved. The probes can cause injuries if used improperly. c. To locate a leak in the wall, make measurements at different locations. The leak is where the meter displays the highest reading. d. After subjecting the meter to a large change in ambient temperature, wait at least 30 minutes before making measurements to guarantee the accuracy of readings. e. When removing/covering the pin cap, the instrumentwill occasionally flash the value on the screen and disappear immediately. Please don't worry, this is due to the interference of static electricity from the human body and does not affect the normal use of the product.
