IMPORTANT: A function or “bump” test, using a known concentration of
calibration gas, should be performed periodically based on instrument use,
exposure to gas, and environmental conditions. The frequency is best
determined by company policy or local regulatory agencies. If an
instrument fails a function or “bump” test, or, if it is dropped, submerged,
or appears damaged, a full calibration is recommended. The safest
approach is to perform a function or “bump” test prior to each day’s use.
Industrial Scientific is not responsible for establishing customer safety
practices and policies.
Zero Screen (if enabled)
If zeroing is enabled (via the Zero Enable
screen in the Configuration section), then
the Zero screen is displayed. From this
screen the user initiates the zeroing process
of the sensors by pressing the Enter button.
The zeroing process should only be initiated
when the instrument is in clean ambient air.
If clean air is not available, a cylinder of
zero grade air should be used. (Refer to the
Zeroing and Calibration processes later in
this manual).
Pressing the On/Off/Mode button from the Zero screen displays the Peak
Readings screen.
Peak Readings Screen
The Peak Readings screen displays the
peak icon, the names of the four installed
sensors, and the corresponding peak
values for each since the last time the peak
value(s) were cleared.
Pressing the Enter button resets all of the
peak values to the current reading.
If one or more toxic gas sensors are installed, then pressing the
On/Off/Mode button from the Peak Readings screen displays the TWA
Readings screen.
If no toxic gas sensors are installed, then pressing the On/Off/Mode
button from the Peak Readings screen returns the user to the Normal
Monitoring screen.
