2. Insert the red test lead into the appropriate input jack based on the measurement type:
• Fun Voltage, Resistance, Continuity, Diode, Capacitance, Frequency, NCV, Live, and Temperature measurements, use the "VΩHz" jack.
• For Current measurements up to 400mA, use the "mA" jack.
• For Current measurements up to 10A, use the "10A" jack.

5.1 Power On/Off and Auto Shut Off

• To power on the multimeter, rotate the rotary dial from the "OFF" position to any desired function.
• To power off, rotate the dial back to the "OFF" position.
• The multimeter features an Auto Power Off function to conserve battery life. It will automatically shut off after a period of inactivity.
• To deactivate Auto Shut Off, press and hold the 'FUNC' button while turning on the meter.

5.2 Aṣayan iṣẹ

Rotate the central dial to select the desired measurement function. For functions with multiple modes (e.g., AC/DC Voltage, Diode/Continuity), press the FUNC button to cycle through the available modes.
