the VX500 will enter into the configuration mode giving
you the opportunity to change the instrument's custom

AS EADING ODE
Once the VX500 enters the Gas Reading Mode the
instrument display will show the concentration of gas
currently being detected along with the corresponding gas
type. For general VOC detection this gas type will be
isobutylene. You may select another gas in the
configuration mode by editing the "favorites" list (see
page 16). Gases selected from the favorites list will use
response factors to determine actual gas concentrations.
These response factors are referenced to isobutylene
unless the VX500 is directly calibrated to the specific gas.
If the monitored concentration of gas exceeds a preset
limit for low alarm, high alarm, STEL, or TWA the
VX500 will alert you by sounding an audible tone in
conjunction with flashing an ultra bright red LED. Alarm
conditions are also activated whenever a sensor fails
calibration, the pump fails or becomes blocked, or the
battery power is too low to operate the VX500.

ONFIGURATION ICONS
The top line of the instrument display will show a series of
icons which identify the instrument's current operating
configuration. These icons are identified below and are
explained in greater detail in later sections of this manual.
