5. Operating Instructions
5.1. Soldering Mode
- Power On: Long press the power button to turn on the device. The OLED screen will display the current temperature and settings.
- Temperature Adjustment: Use the arrow keys (left/right) to navigate the menu and adjust the desired temperature. The temperature range is 100°C to 450°C (212°F to 842°F).
- Quick Heat-up: The device heats up rapidly. Monitor the temperature on the OLED screen.
- Welding Steps:
- Warm Up: Plug in the power supply, hold the electric soldering iron in your hand, and keep the soldering iron head vertical or slightly tilted for operation.
- Dipped in Rosin: After preheating is completed, dip the soldering iron tip in rosin.
- Upper Tin: Add an appropriate amount of tin wire to the soldering iron tip to fully melt it.
- Welding: Melt the tin wire and wrap the solder joint.
- Clean Up: There are impurities on the soldering iron head; you can clean it up on a soaked sponge.
- Cooling: Place the soldering iron carefully to prevent burns and allow the solder joints to cool naturally.
- Automatic Shutdown: The device features an automatic shutdown function to prevent burns and save power. You can set the sleep time in the settings menu (5/10/15/20 minutes or OFF).

5.2. Multimeter Mode
The ANENG SL109 can instantly transform into a multimeter for measuring AC/DC voltage, resistance, and continuity.
- Switch to Multimeter: Ensure the soldering iron tip is removed and the positive watch tip is inserted. Connect the watch pen cable to the Type-C port. The device will automatically enter multimeter mode.
- Voltage Measurement (AC/DC):
- Connect the watch pen cable to the circuit under test.
- The OLED screen will display the measured voltage.
- **Important:** AC voltage can only be measured between 4V and 36V. **Do not measure voltages exceeding 36V** to prevent electric shock.
- For millivolt DC voltage measurements, manual gear switching may be required.
- Resistance Measurement:
- Touch both ends of the resistor with the watch pen cable probes.
- The OLED screen will display the resistance value.
- Continuity Test (Buzzer):
- The buzzer will emit a sound if the resistance is lower than 47 ohms, indicating continuity.
