Operating Mode Overview
The instrument works in either
VOC Mode
for continuous VOC readings or
Tube Mode
for
single-point benzene-specific measurements. The VOC Mode can be configured to read any desired
gas using any correction factor (CF) or lamp, whereas the Tube Mode can only be used for benzene
measurements with a 9.8 eV lamp. When the unit is turned on, it enters
VOC Main Mode
. To
switch between
VOC Mode
and
Tube Mode
, press and hold the Left and Right keys
simultaneously for a few seconds. In each of these main modes, basic users can only see and use a
limited set of functions. Advanced users can access the
Configuration Mode
, which is password
protected, to adjust various parameters. The Configuration Modes are slightly different depending
on whether one is entering from VOC Mode or Tube Mode. Some parameters are not accessible on
the instrument display and the mPower Suite software must be used to change the settings.
