• Ф2: 20A/250V fast-blow fuse for the 20A input.

За замену осигурача:

1. Turn the meter OFF and disconnect all test leads.

6. Reassemble the meter, ensuring all screws are tightened.

КСНУМКС. Решавање проблема

• Random values in mV mode: It is normal for the display to show random values in mV mode when the input terminals are open (not connected to a circuit). Simply short the input terminals to zero the reading. This will not affect measurement results.
• Нема дисплеја или дисплеј је замагљен: Проверите ниво напуњености батерије. Замените батерије ако су празне.
• No reading in current mode: Check if the fuse is blown. Replace if necessary (refer to section 6.3). Ensure test leads are connected to the correct current input jack (mAµA or 20A) and in series with the circuit.
• Приказано је „OL“: Indicates an overload (measurement exceeds the selected range) or an open circuit.
