3. Одвртете ги завртките за прицврстување и внимателно отстранете го капакот.
4. Поврзете ја 9V батеријата со спојката за батеријата, почитувајќи го правилниот поларитет.
5. Ставете ја батеријата во преградата и вратете го капакот, прицврстувајќи го со завртката/шрафовите.

5.2 Тест поврзување на кабелот

Proper connection of test leads is crucial for accurate and safe measurements:

• За повеќето мерења (волуменtage, resistance, capacitance, frequency, temperature, diode, continuity), insert the црвено тест кабел во VΩHzTemp Џек и црна тест кабел во COM џек.
• For current measurements up to 200mA, insert the црвено тест кабел во mA Џек и црна тест кабел во COM џек.
• For current measurements up to 10A, insert the црвено тест кабел во 10 А Џек и црна тест кабел во COM џек.
