Operation Guide
Basic operation involves:
- Selecting the Function: Turn the rotary dial to the desired measurement mode (e.g., V~ for AC voltage, V- for DC voltage, Ω for resistance).
- Connecting Test Leads: Insert the black test lead into the 'COM' jack and the red test lead into the appropriate jack (e.g., 'VΩmA' for voltage/resistance, 'A' or 'mA' for current).
- Performing Measurement: Connect the test leads across the component or circuit to be measured. Read the value displayed on the LCD screen.
- Range Selection: Use the 'RANGE' button to switch between auto-ranging and manual ranging if applicable.
For detailed operating procedures for specific functions, consult the complete user manual.
