this equipment. In addition, confirm that the power is switched off when connecting power supply.
Some sample gas is dangerous to people. When removing this equipment from the process line
for maintenance or other reasons, protect yourself from potential poisoning by using a protective

CAUTION
The cell (sensor) at the tip of the detector is made of ceramic (zirconia element). Do not drop
the detector or subject it to pressure stress.
• Do NOT allow the sensor (probe tip) to make contact with anything when installing the
detector.
• Avoid any water dropping directly on the probe (sensor) of the detector when installing it.
• Check the calibration gas piping before introducing the calibration gas to ensure that there
