OPERATION AND USE
9.
When sampling high areas or overhead lines the use of the optional
extension adapter will allow a broom handle or painters stick to extend
the instrument to the area where sensing must be accomplished. This
adapter slides onto the battery sleeve and is held in place by the locking
nut assembly.
10.
When sampling the appropriate sensors will cause the display to
update when a gas is encountered. Additionally, if a combustible gas is
encountered a series of LEDs on the front of the instrument will illuminate
when the preset concentrations are reached. If any alarm condition exists
for any sensor, based on their preset alarm points, the red (HAZARD 3)
LED will flash and the alarm will sound unless it is muted.
Additionally, the reading for the gas exceeding the alarm set point will
also flash.
