2.5.2 Display Mode
The Display Mode includes all the information from Text Mode
in addition to the options listed below. See Section 4.3 Entering
Programming Mode for details. To access each display, press
[MODE] once.
1. The instantaneous reading and sensor names alternate
every second on the display.
The
instantaneous reading
is the actual gas
concentration in parts per million (ppm) for toxic or VOC
gases, percent of volume for oxygen, and percent LEL for
combustible gases.

2. The
unit display
shows the measurement unit for each
sensor. The toxic and PID sensors are measured in parts-
per-million (ppm). The oxygen and LEL sensors are
measured by percentage (%). The gamma radiation sensor
is measured in micro seiverts-per-hour (µSv/hr) or micro
rems-per-hour (µR/hr).
