MAX Mode

The MAX mode displays the maximum signal, with the date and
time that it was recorded. 2020 continues to log data according to
the selected averaging interval, but only the maximum detected
concentration is displayed on the meter display.
The right soft key is used to clear the meter when displaying MAX.
The "Clr" key only affects the reading that the meter is displaying.
For example , if you display the MAX reading, and you press "Clr",
only the MAX value is cleared. The TWA is still accumulating in the
background.

PEAK Mode

The PEAK mode displays the current detected concentration. The
reading is updated once a second. In the background, the 2020
datalogger is sampling the concentration and measuring minimum,
maximum, and average concentrations for the selected averaging
interval. At the end of every interval, one entry is placed in the
datalogger until the datalogger is full. See
