5.2 Initial Power On and Warm-up
To power on the device, long press the power button. The device will initiate a 20-second warm-up sequence. During this time, the sensors stabilize to ensure accurate readings. Do not take measurements until the warm-up is complete.
5.3 Language and Date/Time Settings
Access the settings menu to configure the device language (English is default) and set the correct date and time. This ensures proper data logging and timestamping of measurements.
6. Operating Instructions
6.1 Measurement Interface
The WT8811 offers both single and multiterm measurement interfaces. You can switch between these views to display individual gas concentrations or all four gas readings simultaneously.
