• ከቮል ጋር ሲሰሩ ጥንቃቄ ያድርጉtagከ30 ቮልት AC RMS፣ 42 ቮልት ጫፍ ወይም 60 ቮልት ዲሲ በላይ። እነዚህ ቮልቶችtagአስደንጋጭ አደጋ ይፈጥራል።
• Before each use, inspect the test leads for damaged insulation or exposed metal. Replace damaged leads immediately.
• የሙከራ መስመሮቹን ወደ ወረዳው ከማገናኘትዎ በፊት የማዞሪያ ማብሪያ / ማጥፊያው በሚፈለገው መለኪያ በትክክለኛው ቦታ ላይ መሆኑን ያረጋግጡ።
• Never use the meter if it appears damaged or if the case is open.
• ቆጣሪውን በሚፈነዳ ጋዝ፣ ትነት ወይም አቧራ አካባቢ ውስጥ አይጠቀሙ።
• Always disconnect the test leads from the circuit before changing the function or range.
• የባትሪው ዝቅተኛ መጠን ያለው አመልካች እንደታየ ወዲያውኑ ባትሪውን ይተኩት፤ ይህም ትክክለኛ ንባብ እንዲኖር ያደርጋል።

4. የአሠራር መመሪያዎች

The VOLTCRAFT VC851 features a rotary dial for selecting primary measurement functions and buttons for secondary functions and settings.

4.1 የተግባር ምርጫ

Turn the central rotary dial to select the desired measurement function (e.g., V for voltage, A for current, Ω for resistance). The meter will automatically select the appropriate range (Auto-Range) for most measurements.

4.2 የመለኪያ ሁነታዎች

• ጥራዝtage (V~ / V-): Measure AC or DC voltage. Select the appropriate voltage range using the rotary dial.
• Current (A~ / A-): Measure AC or DC current. Ensure test leads are connected to the correct current input jacks (mAµA or 10A) and the rotary dial is set to the corresponding current range.
• መቋቋም (Ω): Measure resistance in ohms.
• ቀጣይነት፡ Test for continuity with an audible buzzer.
• የዲዲዮ ሙከራ: Test diodes for proper function.
• አቅም (ኤፍ)፦ Measure capacitance in farads.
