How to Operate
5-1. Preparation for start-up
Before supplying power, read and understand the following precautions. Ignoring these precautions may
cause an electric shock or damage the detector.

Connect the detector to a grounding circuit.

Check that the wiring is connected to external device properly.

Check that the power supply voltage is compliant with the specifications.

Because the external contact may be activated during the adjustment, take measures to prevent an
activated contact from having influences on external device.

Check that there is no clogging or leak in the connected tube. (If the connected tube is clogged, pressure
is applied to the sensor, causing errors and malfunctions.)

Check that the filter is attached properly. (The filter is specified based on the gas to be detected.)
