CTX 300 calibration (for Semiconductor)
This is a
Semiconductor
type sensor.
■
Flip the switch (rep. 1) into the
CAL
position.
Figure 23
■
Ensure that the sensor is in clean air,
otherwise inject synthetic air into it
using the calibration kit and referring
to the recommendations below.
Important: to correctly calibrate a
sensor
equipped
with
a
semi-
conductor cell, use of a humidifier kit
(code 6335919) is MANDATORY.
Using the humidifier kit
-
Lift the lid (ref. A) and, using a
washbottle, moisten the filter,
without saturating it, with distilled
water
-
Replace the lid and check that all
parts are properly assembled and
that the assembly is fully airtight.
-
Adjust the flow rate to 60 l/h and
wait 10 minutes until the humidifier
is fully purged.
-
Apply the gas introduction pipe
(ref. C) to the nose of the sensor
and wait at least five minutes for
the measurement to stabilize.
Note: the sensor must be powered
for at least two hours before any
adjustment can be made.
