| topic | recommendation | note |
| startup & autonomy |
Plan field work around the stated operating autonomy of over 6 hours when fully charged. |
Check charging status before inspection rounds or mobile enforcement use. |
| screening workflow |
Use the panel interface for test review, calibration and parameter setup before entering the target zone. |
The brochure describes a short two-step testing process. |
| sampling point |
Keep the sampling probe positioned consistently when comparing organized and unorganized VOC sources. |
Rated sampling speed at the probe inlet is about 0.5 L/min. |
| response interpretation |
Interpret response-time performance based on the stated 90% final-value criterion for the FID and PID test gases. |
Specified maximum response time is 3.5 seconds in both listed test conditions. |
