5. Operating Instructions
Measurement Display:
Once powered on, the LCD will display the current H2S concentration in the selected unit and the ambient temperature.
Switching Units:
The device supports 4 switchable units for H2S concentration: ppm, VOL%, mg/M³, and LEL%.
Press the UNIT button to cycle through the available measurement units.
Temperature can be switched between °C and °F. Refer to the device's specific settings menu for temperature unit adjustment.
This image illustrates the wide measurement range capabilities of the H2S monitor, showing the four switchable units: 0~100ppm, 0~0.01VOL%, 0~152mg/M³, and 0~0.23LEL%.
Data Hold Function:
Press the HOLD button to freeze the current measurement on the display. Press again to release.
MAX/MIN Value Mode:
Press the MAX/MIN button to view the maximum or minimum H2S concentration recorded since the device was powered on or reset.
Alarm Function:
The H2S Monitor features both a high-decibel buzzer and a flashing red LED light alarm.
Alarms activate when the H2S concentration reaches user-configurable high and low alarm thresholds.

Configuring Alarm Thresholds:
Refer to the detailed instructions in the full manual for specific steps on how to manually configure the high and low alarm threshold values. This typically involves entering a settings menu using a combination of button presses.
6. Calibration
Regular calibration is crucial for maintaining the accuracy of your H2S monitor.
The DANOPLUS DP-8822 supports calibration. For detailed calibration procedures, including zero calibration and span calibration, please consult the comprehensive instruction manual provided with your device or contact DANOPLUS customer support.
Note: Calibration should ideally be performed in a clean air environment for zero calibration and with a known concentration of H2S gas for span calibration.
7. Maintenance and Care
Cleaning:
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
Storage:
Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
If storing for an extended period, remove the batteries to prevent leakage.
