آپریٹنگ ہدایات
This section details the basic operation of the Extech MF100.
- پاور آن/آف: دبائیں پاور button to turn the meter on or off. The display will illuminate.
- Selecting AC/DC Mode: دبائیں MODE DC/AC button to toggle between AC (alternating current) and DC (direct current) magnetic field measurement modes. The selected mode will be indicated on the display.
- Zeroing for DC Measurement: Before taking DC measurements, press the صفر button to calibrate the meter and eliminate any residual magnetic fields. This ensures accurate DC readings.
- پیمائش کرنا: Position the tip of the uniaxial magnetic probe sensor in the magnetic field you wish to measure. The reading will be displayed on the LCD. The N pole/S pole indicator will show the direction of the magnetic field.
- ڈیٹا ہولڈ: دبائیں پکڑو ڈسپلے پر موجودہ پڑھنے کو منجمد کرنے کے لئے بٹن۔ جاری کرنے کے لیے دوبارہ دبائیں۔
- Min/Max Recording: دبائیں آر ای سی button once to enter Min/Max recording mode. The meter will continuously record the minimum and maximum values. Press آر ای سی again to cycle through Min, Max, and current readings. Press and hold آر ای سی to exit Min/Max mode.
- آٹو پاور آف: The meter will automatically power off after a period of inactivity to conserve battery. To disable this feature, refer to the full manual for specific button sequences during power-on.
