The Real-Time Meter provides a visual and auditory means of displaying count data using a histogram with a log scale that gives a relative indication of particulate traffic for each channel. The “Range” slider adjusts the sensitivity of the counters. The slider can be adjusted as the instrument moves nearer or further from the source of contamination to keep the maximum channel near the middle of the indication range. In this way, the Real-Time Meter provides strong visual and auditory feedback of the particulate data in real-time.
The feature can be used to visualize the particle rates of the data arriving at the instrument in real-time. It’s much simpler to visualize than viewing the numerical differential channel figures. The feature might be used by users to simply visualize the ratio of particles per channel arriving at the instrument in order to easily see the distribution of particles by size.
Using the Range slider makes it a powerful tool for tracking particle events to their source. Adjusting the slider as the counts saturate the channel of interest, increases the local sensitivity of the instrument making it very useful for detecting small variations in particle counts for the channel of interest. This allows for ease in distinguishing small variations in counts and thereby more easily track the particles to their source.
