5. ऑपरेटिंग सूचना

The HANMATEK S1 DM20 features auto-ranging for most measurements, simplifying operation.

5.1 पॉवर चालू/बंद

• दाबा SEL button to power on the multimeter.
• The multimeter will automatically power off after a period of inactivity to conserve battery life.
• मॅन्युअली पॉवर ऑफ करण्यासाठी, दाबा आणि धरून ठेवा SEL बटण

5.2 कार्य निवड

The multimeter automatically detects the measurement type (voltage, resistance, continuity) when test leads are connected. For specific functions or to switch between AC/DC, press the SEL बटण थोडक्यात.

५.२ मूलभूत मोजमापे

• खंडtage (AC/DC): Connect test leads in parallel to the circuit or component. The multimeter will automatically detect AC or DC voltage.
• Current (AC/DC): Connect test leads in series with the circuit. Use the एमए terminal for current measurements. Ensure the circuit is de-energized before connecting.
• प्रतिकार: Connect test leads across the component. Ensure the component is isolated from power.
• सातत्य: Connect test leads across the circuit. A buzzer will sound if continuity is detected.
• डायोड: Connect test leads across the diode.
• वारंवारता: Connect test leads to the signal source.

5.4 गैर-संपर्क खंडtage (NCV) शोध

NCV फंक्शन AC व्हॉल्यूम शोधण्याची परवानगी देतेtage थेट संपर्काशिवाय.

1. दाबा NCV / Flashlight button to activate NCV mode.
2. Place the NCV detection area (top of the multimeter) near the conductor.
3. जर AC व्होल्tage is detected, the NCV LED will flash, and the buzzer will sound. The LCD screen will display segments ('-' to '----') indicating signal strength.

5.5 Backlight and Data Hold

• बॅकलाइट: दाबा Backlight / Data Hold button briefly to turn the LCD backlight on/off.
• डेटा होल्ड: दाबा आणि धरून ठेवा Backlight / Data Hold डिस्प्लेवरील वर्तमान वाचन गोठवण्यासाठी बटण. सोडण्यासाठी पुन्हा दाबा.

5.6 फ्लॅशलाइट

• दाबा आणि धरून ठेवा NCV / Flashlight button to turn the built-in flashlight on/off.

6. देखभाल

• साफसफाई: Wipe the multimeter with a damp कापड आणि सौम्य डिटर्जंट. घर्षण किंवा सॉल्व्हेंट्स वापरू नका.
• स्टोरेज: Store the multimeter in a dry, cool place away from direct sunlight. If storing for extended periods, remove the batteries to prevent leakage.
• बॅटरी बदलणे: Replace batteries promptly when the low battery indicator appears to ensure accurate readings. Refer to Section 4.2 for instructions.

7. समस्या निवारण

• No Display/Power On: बॅटरीची स्थापना तपासा आणि बॅटरी संपल्या नाहीत याची खात्री करा. आवश्यक असल्यास बदला.
• चुकीचे वाचन: Ensure test leads are properly connected and not damaged. Verify the correct measurement function is selected (though auto-ranging handles most). Check battery level.
• No NCV Detection: Ensure NCV mode is activated. The detection area must be close to the AC voltagई स्रोत.
• Auto Power Off Too Soon: This is a power-saving feature. The device will power off after a period of inactivity.
