Matters needing attention

Ø In environments with EMC problems, shielded cables must be used.

Ø When the module is started cold, the preheating time should not be less than 2 minutes.

Ø The sensor should be calibrated regularly, and no more than 3 months is recommended.

Ø Do not use the sensor in a dust dense environment for a long time.

Ø Please pay attention to the wiring of the positive and negative terminals of the power supply and the signal output terminals. Do not connect backward.

Ø High concentration of chemical pollution will lead to the damage of sensor polymerization layer, therefore, the product should be kept and used away from chemical pollution sources.

Ø Please refer to the relevant national product installation standards for the installation process.
