3. Opsætning

3.1 Batteriinstallation

1. Sørg for, at enheden er slukket.
2. Find batterirummet på bagsiden af ​​enheden.
3. Åbn batterirummets dæksel.
4. Isæt tre (3) AA-batterier, og sørg for at polerne vender korrekt (+/-). Bemærk: Batterier er ikke inkluderet.
5. Luk batterirummets dæksel forsvarligt.

3.2 Indledende tænding

Turn the central rotary knob from the 'OFF' position to any measurement function (e.g., 'AUTO' for voltage) to power on the device.

3.3 Quiet Mode Activation

To enter mute mode, hold down the F4 key while turning the rotary knob to power on the machine.

4. Betjeningsvejledning

4.1 Oscilloskopets drift

The ET2010A features a graphical display for waveform analysis.

1. Aktivering af oscilloskoptilstand: Turn the rotary knob to the 'OSC' position.
2. One-Touch Automatic Waveform Capture: Press the 'AUTO' button (F1) to automatically capture and display the waveform.
3. Adjusting Waveform Parameters: Use the F2 and F3 buttons to adjust the time base and amplitude of the displayed waveform.
4. Triggertilstande: The device supports three waveform scanning modes:
   • Automatisk tilstand: Automatically acquires waveform data without a specific trigger signal.
   • Normal tilstand: Acquires waveform data when a trigger signal is detected.
   • Enkelt tilstand: Acquires a single waveform data when a trigger signal is detected.
5. Gemmer bølgeformer: Press the 'SAVE' button (F4) to save the current waveform. The device can store up to 10 waveforms.

4.2 Multimeterbetjening

Turn the rotary knob to the desired measurement function. Connect the test leads appropriately to the COM and VΩCx or 10A jacks.

• Voltage-måling (DC/AC): Select 'V' (DC or AC) on the rotary knob. The device supports auto-ranging.
• Strømmåling (DC/AC): Select 'A' (DC or AC) on the rotary knob. Ensure proper connection for current measurement (10A jack).
• Modstandsmåling: Select 'Ω' on the rotary knob.
• Kapacitansmåling: Select 'Cx' on the rotary knob.
• Frequency/Duty Cycle Measurement: Select 'Hz/%' on the rotary knob.
• Diode test: Select the diode symbol on the rotary knob.
• Kontinuitetstest: Select the continuity symbol (beep) on the rotary knob.

4.3 Specialfunktioner

• REL (relativ måling): Press the 'REL' button to enter relative measurement mode. This function effectively eliminates lead resistance, distributed capacitance, and interference signals, providing more accurate readings.
• MAX/MIN Test: Use the 'MAX/MIN' function to record the maximum and minimum values during a measurement process, aiding in data analysis.
• Justering af baggrundsbelysning: The display features a bright backlight for clear visibility.
• Auto-søvn: The device will automatically shut down after 15 minutes of no operation to conserve battery life. This feature can be disabled in settings.

6. Vedligeholdelse

6.1 Generel pleje

• Hold enheden ren og tør. Tør af med en blød, tør klud.amp klud om nødvendigt. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
• Undgå at udsætte enheden for ekstreme temperaturer, fugt eller direkte sollys.
• Store the device in a safe place when not in use, preferably in its carrying pouch, to prevent damage.
• Hvis enheden ikke skal bruges i længere tid, skal batterierne fjernes for at forhindre lækage.

6.2 Udskiftning af sikringer

The device is equipped with a 10A/250V double protective tube for overload protection. If the fuse blows due to an overload, it must be replaced with a fuse of the same type and rating to ensure continued safety and functionality.

1. Ensure the device is powered off and disconnect all test leads.
2. Refer to the device's internal diagram (if available in the full manual) for the exact location of the fuse.
3. Åbn forsigtigt c'enasing (if user-serviceable) or consult a qualified technician.
4. Replace the blown fuse with a new 10A/250V fuse.
5. Luk casing sikkert.

7. Fejlfinding

• Enheden tændes ikke: Kontroller batteriinstallationen, og sørg for, at batterierne ikke er afladede. Udskift om nødvendigt.
• Unøjagtige aflæsninger: Ensure test leads are properly connected and not damaged. Use the REL function to eliminate interference. Verify the correct measurement mode is selected.
• Ingen visning af bølgeform: Check the input signal. Ensure the oscilloscope is in the correct mode (Auto/Normal/Single) and trigger settings are appropriate.
• Skærmen er svag eller ulæselig: Adjust the backlight. If batteries are low, replace them.

For persistent issues not covered here, please consult the full user manual or contact customer support.
