Warnings
For safety reasons, this equipment must be operated and
serviced by qualified personnel only. Read and understand the
user manual completely before operating or servicing.
Battery Pack
Use only RAE Systems battery packs (P/N 046-3007-000 or 046-3051-000). 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/replace 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
While the EntryRAE has been factory calibrated prior to shipment, transport
and storage after leaving the factory can affect the sensors. Therefore, any
newly purchased RAE Systems Instrument should be fully calibrated 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 calibration gas(es) before each day’s
use. (Refer to “Calibration” on page 10.)
Caution!
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 0% to +20% of actual. Accuracy may
be corrected by calibration. Refer to “Calibration” on page 10.)
Long-Term Storage
Reliable performance of this gas detector is based upon regular usage.
For long term storage, the battery should be disconnected. Preparation for
use after long storage requires installation of the batteries and a warm-up
period of at least 10 minutes for the sensors to equilibrate. The user should
recognize that sensor life is based upon the purchase date.
Readings
Any rapid up-scale reading followed by a declining or erratic reading may indicate
a gas concentration beyond the upper scale limit, which may be hazardous.
CAUTION:
HIGH OFF-SCALE READINGS MAY INDICATE AN EXPLOSIVE
CONCENTRATION!
