Displays
The 2020 has a meter display for reporting detected concentration,
and a status display used to display status information and guide you
through configuration options. All functions of the 2020 will be
controlled or reported using one of these displays.
Meter Display
The meter display is a 4 digit display. It will always be used for
reporting detected concentration. When the detector and pump are
off, the meter display will be blank.
In order to accommodate the range of concentrations 2020 can
detect, the meter reading will be reported using one of 2 resolutions.
A resolution of 0.1 will be used for concentrations below 100 ppm,
and a resolution of 1 will be used for concentrations above 100 ppm.
The meter display reports PEAK, MAX, STEL or TWA
concentration. The update rate is dependent on the reading being
reported. See STEL, TWA, MAX and PEAK Operation on page 46
for a description of these measurements.
Status Display
The status display is a 2 line by 16 character display. The top line is
used to display status information and prompts you for information.
The bottom line is used for soft key names. Up to 3 names can be
displayed for the three soft keys. If a name does not appear for a
soft key, then the soft key has no associated function.
