4.3.1. Sampling
The Operate screen displays current sample information when the unit is sampling (real
time data). Concentration values are time dependent so these values may fluctuate
early in the sample; however, after several seconds the measurement will stabilize.
4.3.2. Sample Status
The top of the Operate screen displays the status of the AEROCET 532 while the unit is
sampling. The time remaining is shown at the top left of the screen. A status bar fills
with green as time progresses. If a hold time is entered, the status bar will fill yellow
during the hold time.
4.3.3. Sample History
Sample history (previous data) can be viewed on the Operate screen when the unit is
stopped or sampling. Pressing the knob puts the operate screen in History Mode.
History mode allows you to scroll through previously recorded samples and view the
historical data.
In history mode, use the dial action of the rotary knob to scroll through the previous
sample data records. Note the red arrows at the top indicate record scrolling mode (see
Figure 6). To see additional data for a given record, press down on the rotary dial to
enter the data scrolling mode. Using the dial action of the rotary knob will scroll the
data up and down and enable users to view the data stored on each channel. Data
scrolling mode is indicated by black arrows on the right side of the display (see Figure
7). Press down on the rotary knob again to switch back to record scrolling mode; use
the ESC button to exit history mode. A new sample can be started without exiting the
history mode by pressing the START button.
