I. Product Introduction:

DW-30FC SmartDust sampler. This instrument features a single-chip microcomputer as the intelligent control central processing unit, enhancing its applicability. The intelligent operation platform is built on an intelligent, refined internal management system, with menu settings, the ability to remember the last sampling time, continuous and intermittent sampling, intelligent power management, real-time battery display, charging indicator, and imported hollow cup motor drive. With a large LCD screen display, automatic shutdown after no operation, etc., it is a practical dust sampler.

III. Usage and Maintenance:

1. Sampling: Attach the sampling head with the filter holder, press the "Power" button for two seconds to enter the startup screen. Press the "Cancel" button to access "Function Settings." Use the up and down arrows to navigate to "Sampling Mode Settings" or "System Function Settings." If selecting "Sampling Mode Settings," press "Confirm" then use the left and right arrows to choose continuous or intermittent sampling (usually continuous). Use the up and down arrows to select the sampling and stop times (in intermittent sampling mode). For system function settings, suggest turning off after 1-3 seconds of no operation, with the backlight on for about 5 seconds. After setting, press "Cancel" to confirm the sampling time. Once the menu settings are adjusted, subsequent startups only require pressing the "Power" button, selecting the desired time, and pressing "Confirm" to start sampling.

2. Charging: The instrument's display shows battery capacity.This graphic depicts a fully charged state.When the graphic isIndicates under-voltage requiring recharge. Simply plug the battery cable into household AC power and connect it to the sampler for automatic charging. Once charging is complete, the main unit's indicator light changes from red to green.

3. Caution: If not used for more than 3 months, please recharge the battery to ensure its longevity.

In dusty air, the sampling head with a filter membrane should be installed before turning on the machine; otherwise, dust particles may enter the machine and affect the cleanliness of the gas path components.
