CTX 300
ANALOGIC GAS DETECTOR
USER MANUAL
18 NP300GB
Revision O.0
The output signal should be:
U = 880 mV + 3520 mV x Cal gas concentration
Sensor measurement range
Example
Sensor measure (% of full range) Output signal
(mV)
0 880
50 2 640
100 4 400
•
Stop injecting the calibration gas.
•
Verify that the reading returns to zero (880 mV). If it does not, repeat the entire procedure.
•
Calibration is complete.
•
Flip the switch (ref. 1) into the MES (Measure) position.

5.2 Replacing a sensor
Sensors must be replaced:
•
When calibration is no longer possible (no sensitivity);
•
During preventative maintenance.
The replacement sensor should be identical to the original sensor (same gas, same range). After
a sensor has been replaced, a calibration or test (for pre-calibrated sensors) must be conducted.
5.3 Disposal
For the preservation, protection and improvement of environmental quality, and for
the protection of human health and the prudent and rational utilization of natural
resources, the CTX 300 must be disposed of separately from electronic equipment
and cannot be disposed of with normal household waste. The user therefore has an
obligation to separate the CTX 300 sensor from other waste to ensure that it is
recycled safely for the environment. For further details on existing collection sites,
contact the local administration or seller of the product.
