5. Setup

5.1 Initial Charging

Before first use, ensure the multimeter is fully charged. Connect the included charging cable to the multimeter's charging port and a suitable USB power source (e.g., computer USB port, USB wall adapter).

• The battery indicator on the display will show charging status.
• A full charge typically takes a few hours.

5.2 Connecting Test Leads

To perform measurements, connect the test leads to the appropriate input jacks:

• Insert the black test lead into the "COM" (Common) jack.
• Insert the red test lead into the "INPUT" jack for most measurements (voltage, resistance, etc.).

6. Operating Instructions

6.1 Powering On/Off

Press and hold the power button (usually marked with a power symbol) to turn the multimeter on or off.

6.2 Automatic Measurement Mode

The Srliya S20 features an intelligent auto mode that simplifies measurements:

• Upon powering on, the meter defaults to "AUTO" mode.
• In "AUTO" mode, the multimeter automatically identifies the type of measurement (AC voltage, DC voltage, resistance) and selects the appropriate range.
• Simply connect the test leads to the circuit or component you wish to measure.

6.3 Reading the Display

The color LCD provides comprehensive information:

• The main large digits show the primary measurement value.
• Smaller digits may display secondary information like frequency.
• An analog bar graph provides a quick visual representation of the measured value.
• Polarity indication: A "-" symbol indicates negative polarity.
• "0L" or "-0L" indicates an overrange condition.
