6. Operating Instructions
This section provides general instructions for using the ANENG DT-9205A multimeter for various measurements.
6.1. General Operation
- Turn on the multimeter using the power switch.
- Select the desired measurement function by rotating the function knob.
- Connect the test leads to the appropriate jacks and then to the circuit or component under test.
- Read the measurement value on the digital display.
- To conserve battery life, the multimeter features an auto power-off function.
6.2. Measuring DC Voltage (V–)
- Connect the black lead to COM and the red lead to VΩHz.
- Rotate the function knob to the desired DC Voltage (V–) range (e.g., 20V for a 9V battery).
- Connect the test leads in parallel across the component or circuit to be measured.
- Read the voltage value on the display. Observe polarity if indicated.
6.3. Measuring AC Voltage (V∼)
- Connect the black lead to COM and the red lead to VΩHz.

- No display or dim display: Check battery level and replace if necessary. Ensure the power switch is ON.
- Incorrect readings: Verify the function knob is set to the correct measurement type and range. Check test lead connections. Ensure the circuit is de-energized for resistance/continuity/diode tests.
- 'OL' (Overload) reading: The measured value exceeds the selected range. Switch to a higher range or check for an open circuit.
- No continuity beep: Check if the circuit is truly continuous. Ensure the function knob is on the continuity setting.
9. User Tips
- Always start with the highest range when measuring an unknown voltage or current to prevent overloading the meter.
- For precise resistance measurements, short the test leads together and note the resistance. Subtract this value from your measurement to compensate for lead resistance.
- When measuring capacitance, ensure the capacitor is fully discharged before connecting the meter.
- Utilize the built-in back support stand for hands-free operation, especially when working on a workbench.
