MultiRAE Plus Usage Overview
Storage
Always keep the MultiRAE Plus on charge in a dry indoor area when
not in use.
If the MultiRAE Plus is to be stored more than 2 weeks off the charger,
it is recommended to remove the Li-ion battery. Upon reinstalling the
battery, it will need a complete charge and some sensors (like NO
and NH
3
) may require time to warm up, anywhere from 20 minutes to
24 hours.
Refer to Technical Note-114 Sensor Specifications and Cross
Sensitivities.
The clock will also need to be reset.
Confined Space Pre-Entry Test
Test the atmosphere in the confined space by sampling air at 3 levels
(Top, Middle and Bottom) in the Confined Space. Give the instrument
time to sample the gas at each level - the correct sampling time is 60
seconds plus 1 second per every foot of hose.
Alarms
If there are any gas
ALARMS
at any level in the confined space it is
not safe.
DO NOT ENTER!
Identify the alarm condition and then start your preventive actions
according to your company’s Confined Space Entry procedures.
No Alarms
If there are no alarms, the Confined Space may be safe for entry.
Disconnect the hose before carrying the MultiRAE Plus into the
Confined Space. If monitoring is to be done by a Confined Space
attendant, they should continue to monitor while you enter the area.
If the unit alarms and “BAT” is displayed, the battery needs to be
charged. There is 15 minutes or less of run time remaining.
Leave the
Confined Space immediately!
