Calibration
All newly purchased ToxiRAE II instruments
should be bump tested by exposing the sensor
to known concentration calibration gas before
the instrument is used or put into service. A
bump test is dened 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 ToxiRAE II 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.
• RAE Systems recommends using RAE
calibration gas.
• 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.
For maximum safety, the accuracy of the monitor
should be checked by exposing the sensor to
known concentration calibration gas before each
day’s use (eld calibration).
