Replacing the Sensor
ToxiRAE II models are designes so that you can easily
change the sensor .
New sensors need to warm up before first calibration and use.
(
See
Table A
for required warm-up times.
)
To replace the sensor, use the calibration adapter to turn the
sensor cap one quarter-turn counterclockwise . Next pull off
the sensor cap .
Then carefully remove the sensor by pulling it straight out .
Also remove the filter that is held in place with an o-ring,
located in the ToxiRAE II housing above the sensor .
Replace these with a new sensor and filter. Replace the
filter (P/N: 045-2054-000) when it appears dirty or when the
sensor is replaced . (
See
Table A
for sensor part numbers.
)
Sensors are not interchangeable. Use only RAE Systems sensors,
and use only the sensor type specified for your ToxiRAE II
monitor. Use of non-RAE Systems components will void the
warranty and can compromise the safe performance of this
product.
Make sure the pins are not bent or corroded . Align the pins
to the corresponding holes and push the sensor straight in .
The sensor should fit flush against the printed circuit board.
Replace the sensor cap and calibrate and test the monitor
before placing it back in service .
