WARNINGS
Use only RAE Systems rechargeable battery pack part number 020-3402-000, or alkaline battery pack part
number 020-3403-000. Use only DURACELL MN1500 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 suitability for intrinsic safety. Recharge batteries only in non-hazardous
locations. Do not connect the serial communication port in a hazardous location.
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.
All newly purchased RAE Systems instruments should be bump tested by exposing the sensor(s) to known
concentration calibration gas before the instrument is put into service, and later, prior to each use. A bump test is
defined as a brief exposure of the monitor to the calibration gas and the sensors to show response and trigger the
lowest alarm set point for each sensor.
•
The QRAEII Multi Gas detector must be calibrated if it does not pass a Bump Test, or at least once
every 180 days, depending on use and sensor exposure to poisons and contaminants.
•
Calibration intervals and bump test procedures may vary due to national legislation.
•
When using an H
2
S sensor in a QRAE II, RAE Systems recommends using RAE calibration gas
cylinders with a 4 gas mix containing 10 ppm H
2
S, 50 ppm CO, 50% LEL Methane, and 18% Oxygen.
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.
