To ensure accurate readings with your TROTEC PC220 Particle Counter, regular sensor cleaning is essential. Here's how to clean the sensor: First, unscrew the metallic measuring funnel from the device. Next, connect the calibration hose to the suction nozzle and attach the zero filter. Initiate a measurement in the "Cumulative" particle measurement mode until each channel displays "0". The calibration procedure should complete within 5 minutes. If all channels don't register zero values within this timeframe, please contact Trotec customer support for assistance. The zero filter, included with your device, is designed to aid in this cleaning process and maintain optimal sensor performance.
