Battery
The instrument uses a 9V dry battery or 9V rechargeable battery. If you do not use the instrument for a long time, be sure to remove the battery from the battery compartment, otherwise, the battery will automatically discharge and leak and corrode. -
Power ON/OFF
Before starting the measurement, make sure that the sensor of the instrument is dry. If there is moisture on the sensor, please wipe it dry with a cloth before performing the measurement operation. -
Measurement
For best accuracy, please press the instrument’s sensor on the flat area of the measured material. Ideally, the thickness of the measured material should be at least 19mm.
If your test object is too thin, the instrument will measure the material below it and produce inaccurate readings. One way to compensate for thin materials is to stack measurement materials.
warning: This instrument is a capacitive value detection instrument, please do not use it for non-capacitive moisture measurement. Such as metal, conductive film and other conductive objects.
NOTE
- In the process of storage and use, you must pay attention to keeping the instrument dry and clean to ensure the accuracy of the measurement.
- When the instrument is not in use, please store the instrument in a stable, dust-free, and avoid direct sunlight.
- During the use of the instrument, please do not press or knock the body strongly.
- The measuring object of the instrument is a solid surface, please do not use it for measuring organic liquids.
- Please do not attach the sensor of the instrument to water for measurement.
- Please use the specified battery for power
Kind reminder
The calibration mode is suitable for Benchmark adjustments made by the
instrument deviations due to environmental differences (high temperature and
high humidity, low temperature and low humidity, high altitude, and other
unconventional environments).
Benchmark adjustments have an impact on each model.
The instrument may need to be calibrated if the following conditions occur:
- When the instrument sensor is dry, turn on the instrument and far away from any measured object, the value display is not “00.0%”
- ln”SOFT WOOD” mode, the value will be displayed as “00.0%” when different parts are measured
maintenance
- When the battery power is low, the backlight will be dim. To ensure accurate measurement of the instrument, please replace it with new batteries in time.
- Use a dry and soft cloth to wipe off the dirt on the instrument. Do not use detergents or solvents.
- Do not stick any labels or nameplates (especially metal nameplates) on the sensor. Please use the attached protective cover to store and carry the instrument.
Waste treatment
Damaged instruments, accessories (batteries, etc.), and packaging materials must be recycled and reused in a manner that meets environmental protection requirements.
