WARNINGS
Explosion Hazard
– Substitution of components may impair
suitability for Division 2 hazardous locations.
Use only RAE Systems rechargeable battery pack part number
029-3153-200, or alkaline battery pack part number 029-3154-
000. Use only DURACELL MN1400 or ENERGIZER E93 C
size batteries with alkaline battery pack. This instrument has
not been tested in an explosive gas/air atmosphere having an
oxygen concentration greater than 21%. Substitution of
components may impair safety. Recharge/replace batteries
only in non-hazardous locations.
STATIC HAZARD:
Clean only with a damp cloth.
For safety reasons this equipment must be operated and
serviced by qualified personnel only. Read and understand
instruction manual completely before operating or servicing.
Only the combustible gas detection portion of this instrument
has been assessed for performance.
Before each day’s usage, sensitivity must be tested on a
known concentration of methane gas equivalent to 20% to 50%
of full-scale concentration. Accuracy must be within ±20% of
actual. Accuracy may be corrected by calibration procedure.
Any rapid up-scale reading followed by a declining or erratic
reading may indicate a gas concentration beyond upper scale
limit which may be hazardous.
The calibration of all newly purchased RAE Systems
instruments should be tested by exposing the sensor(s) to
known concentration calibration gas before the instrument is
used or put into service. For maximum safety, the accuracy of
the AreaRAE Steel should be checked by exposing the
sensor(s) to known concentration calibration gas before each
day’s use.
