- Power Off: Press and hold the power button again until the device powers down.
4.3 Automatic Calibration
The NOYAFA JMS19 features an automatic calibration function. The device is factory calibrated and will perform self-calibration upon startup, ensuring accurate data without manual intervention. For optimal performance, ensure the device is in a clean air environment during startup for initial calibration.
5. Operating Instructions
5.1 Real-time Monitoring
Once powered on, the device will immediately begin real-time monitoring of the four gases and display their concentrations on the LCD. The temperature will also be shown.
5.2 Alarm Indications
When gas concentrations exceed preset safe limits, the device will activate its multi-tiered alarm system:
Figure 5.1: Triple Alarm Indication.
- Audible Alert: A loud beeping sound.
- Vibration Alert: The device will vibrate.
- Visual Alert: An alarm light (LED) will flash, and the display may show an alarm indicator.
In case of an alarm, evacuate the area immediately and follow emergency procedures.
5.3 Data Hold Function
