• مزاحمت کی پیمائش: For precise determination of moisture content in wood using the integrated pins.

استعمال کریں۔ M button to toggle between measurement modes. The display will indicate the active mode.

5.2 پیمائش کرنا

1. For Dielectric Measurement: Place the back of the device flat against the surface of the material you wish to measure. Ensure full contact. The reading will appear on the display.
2. For Resistance Measurement (Wood): Carefully press the two measurement pins into the wood surface. Ensure both pins penetrate the material. The moisture content will be displayed.
3. Read the value on the digital display.

5.3 درجہ حرارت کا معاوضہ۔

For accurate resistance measurements in wood, the device offers automatic temperature compensation. Enter the material temperature using the سیٹ button and navigation controls (if available, based on typical Wohler interfaces, assuming the SET button is for settings/calibration). Refer to the on-screen prompts for specific temperature input procedures.

5.4 الارم فنکشن
