Sikkerhedsoplysninger
Please read and understand all safety precautions before operating the Extech MF100. Failure to follow these instructions may result in injury or damage to the device.
- Forsøg ikke at åbne måleren casing. Service bør kun udføres af kvalificeret personale.
- Keep the device away from strong electromagnetic fields that are not being measured, as this may affect accuracy.
- Sørg for, at batterirummet er forsvarligt lukket før brug.
- Bortskaf batterier i henhold til lokale regler.
- Undgå at tabe måleren eller udsætte den for hårde stød.
Opsætning
- Batteri installation: Open the battery compartment cover on the back of the meter. Insert the included 9V battery, observing the correct polarity. Close the cover securely.
- Probeforbindelse: Connect the uniaxial magnetic probe sensor cable to the input jack located at the top of the MF100 meter. Ensure the connection is firm.
- Beskyttelsesdæksel: Place the protective cover over the probe tip when not in use to prevent damage.
Betjeningsvejledning
This section details the basic operation of the Extech MF100.
- Tænd/sluk: Tryk på MAGT button to turn the meter on or off. The display will illuminate.
- Selecting AC/DC Mode: Tryk på 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 NUL button to calibrate the meter and eliminate any residual magnetic fields. This ensures accurate DC readings.
- Målinger: 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.
- Data Hold: Tryk på HOLDE knappen for at fryse den aktuelle aflæsning på displayet. Tryk igen for at slippe.
- Min./maks. registrering: Tryk på REC button once to enter Min/Max recording mode. The meter will continuously record the minimum and maximum values. Press REC again to cycle through Min, Max, and current readings. Press and hold REC to exit Min/Max mode.
- Automatisk sluk: 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.
