Warnings
Battery Pack
Use only RAE Systems battery packs, part number 500-
0029 or 500-0037. This instrument has not been tested in an
explosive gas/air atmosphere having an oxygen concentration
greater than 21%. Substitution of components may impair
intrinsic safety. Recharge batteries only in non-hazardous
atmospheres.
Computer Interface
Do not transfer data by means of the computer interface cable
in hazardous atmospheres.
Static Hazard
Clean only with a damp cloth.
Calibration
The calibration of any newly purchased RAE Systems
Instrument should be tested by exposing it to known
concentration calibration gases before the instrument is put
into service for the first time. For safety, check the accuracy of
the monitor by exposing the sensors to known concentration
calibration gas(es) before each day’s use.
Readings
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.
For safety reasons this equipment must be operated and
serviced by qualified personnel only. Read and understand
the instruction manual completely before operating or
servicing.
