5. જાળવણી

5.1 બેટરી રિપ્લેસમેન્ટ

When the low battery indicator appears on the LCD, replace the 9V battery as described in Section 3.1. Using a low battery can lead to inaccurate readings.

5.2 સફાઈ

Wipe the multimeter's casinજાહેરાત સાથે gamp કાપડ અને હળવા ડિટર્જન્ટનો ઉપયોગ કરો. ઘર્ષક અથવા દ્રાવકનો ઉપયોગ કરશો નહીં. ઉપયોગ કરતા પહેલા ખાતરી કરો કે ઉપકરણ સંપૂર્ણપણે સુકાઈ ગયું છે.

5.3 ફ્યુઝ રિપ્લેસમેન્ટ

The ANENG SZ308 is equipped with internal fuses for overload protection. If the multimeter fails to measure current, the fuse may need replacement. Refer to the internal diagram or contact customer support for guidance on fuse specifications and replacement procedures. Always replace with a fuse of the same type and rating.

6. મુશ્કેલીનિવારણ

• કોઈ ડિસ્પ્લે નહીં અથવા ઝાંખું ડિસ્પ્લે નહીં: Check battery installation. Replace the 9V battery if low battery indicator is on or if the display is dim.
• No reading in current mode: Check if the test leads are connected to the correct current jacks (VΩmA or 10A) and if the fuse is intact.
• "OL" (ઓવરલોડ) પ્રદર્શિત: The measured value exceeds the selected range. Select a higher range or ensure the circuit is within the multimeter's capabilities.
• અચોક્કસ વાંચન: Ensure the battery is not low, test leads are properly connected, and the correct function is selected. Avoid strong electromagnetic interference.
