- Sørg for, at multimeteret er slukket, og frakobl alle testledninger.
- Find batteridækslet på bagsiden af enheden.
- Skru fastholdelsesskruen(e) ud, og fjern forsigtigt dækslet.
- Connect the new 9V battery to the battery clip, observing correct polarity.
- Placer batteriet i batterirummet, og sæt dækslet på igen, og fastgør det med skruen/skruerne.
Note: If the low battery indicator appears on the display, replace the battery promptly to maintain measurement accuracy.
5. Betjeningsvejledning
Before taking any measurements, ensure the test leads are correctly inserted into the appropriate input jacks and the function switch is set to the desired measurement type.
5.1 Måling af DC Voltage (DCV)
- Insert the red test lead into the "VΩmA" jack and the black test lead into the "COM" jack.
- Set the function switch to the desired DCV range (e.g., 20V, 200V). If the voltagHvis e er ukendt, skal du starte med det højeste område og sænke det efter behov.
- Connect the test leads across the component or circuit to be measured, observing polarity (red to positive, black to negative).
- Læs bindtage -værdi på displayet.
5.2 Måling af AC Voltage (ACV)
- Insert the red test lead into the "VΩmA" jack and the black test lead into the "COM" jack.
- Set the function switch to the desired ACV range (e.g., 200V, 750V).
- Tilslut testledningerne på tværs af AC-volumentage kilde.
- Læs bindtage -værdi på displayet.
5.3 Measuring DC Current (DCA)
CAUTION: Never connect the multimeter in parallel with a voltagkilden ved måling af strøm. Dette kan sprænge sikringen eller beskadige måleren.
- For currents up to 200mA, insert the red test lead into the "VΩmA" jack. For currents up to 10A, insert the red test lead into the "10A" jack. Insert the black test lead into the "COM" jack.
- Set the function switch to the desired DCA range (e.g., 20mA, 200mA, 10A).
- Turn off power to the circuit. Break the circuit and connect the multimeter in series with the load.
- Tilslut strøm til kredsløbet, og aflæs strømværdien på displayet.
5.4 Measuring AC Current (ACA)
The Pro'sKit MT-1270 supports AC current measurement. Follow the same procedure as for DC Current, but select the appropriate ACA range on the function switch.
- For currents up to 200mA, insert the red test lead into the "VΩmA" jack. For currents up to 10A, insert the red test lead into the "10A" jack. Insert the black test lead into the "COM" jack.
- Set the function switch to the desired ACA range.
- Turn off power to the circuit. Break the circuit and connect the multimeter in series with the load.
- Tilslut strøm til kredsløbet, og aflæs strømværdien på displayet.
5.5 Måling af modstand (Ω)
- Insert the red test lead into the "VΩmA" jack and the black test lead into the "COM" jack.
- Set the function switch to the desired Resistance (Ω) range.
- Ensure the circuit or component under test is completely de-energized.
- Tilslut testledningerne på tværs af komponenten.
- Læs modstandsværdien på displayet.
5.6 Måling af kapacitans (F)
- Insert the red test lead into the "VΩmA" jack and the black test lead into the "COM" jack.
- Set the function switch to the Capacitance (F) range.
- Sørg for, at kondensatoren er helt afladet før måling for at forhindre beskadigelse af måleren.
- Tilslut testledningerne på tværs af kondensatorterminalerne.
- Læs kapacitansværdien på displayet.
5.7 Diodetest
- Insert the red test lead into the "VΩmA" jack and the black test lead into the "COM" jack.
- Set the function switch to the Diode symbol (►|).
- Connect the red lead to the anode and the black lead to the cathode of the diode. The display will show the forward voltage drop.
- Vend ledningerne om. Displayet skal vise "OL" (Open Loop) for en god diode.
5.8 Transistor (hFE) Test
- Indstil funktionskontakten til hFE-positionen.
- Identificer om transistoren er NPN eller PNP.
- Insert the transistor's emitter, base, and collector leads into the corresponding holes in the hFE socket on the multimeter.
- Read the hFE value (DC current gain) on the display.
5.9 Kontinuitetstest
- Insert the red test lead into the "VΩmA" jack and the black test lead into the "COM" jack.
