5. Instrukcja obsługi

5.1 Włączanie/wyłączanie zasilania

To power on the multimeter, rotate the gear rotating disc from the "OFF" position to any desired measurement function. To power off, rotate the disc back to the "OFF" position.

5.2 Automatyczne i ręczne ustawianie zakresu

Figure 5.1: Rotary switch indicating Automatic and Manual Ranging sections.

• Funkcja automatycznego zakresu: When the rotary switch is set to the "AUTOMATIC RANGE" section, the multimeter automatically selects the appropriate measurement range for AC/DC voltage, resistance, capacitance, frequency, on/off (continuity), and diode tests. This simplifies operation.
• Manual Range Function: When the rotary switch is set to the "MANUAL RANGE" section, you can manually select specific ranges for NCV, Live wire identification, AC/DC voltage, AC/DC current, temperature, and resistance measurements. This provides greater control for experienced users.
