WARNING
Handle it with care. Be sure not to accidentally drop it.
Handle safely to avoid injury.
Connect the power supply cord only after confirming that the supply voltage matches the rating of
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
mask or ventilating the area well.
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
is no leakage of the gas. If there is any leakage of the gas, the moisture drawn from the
sample gas may damage the sensor.
• The detector (especially at the tip) becomes very hot. Be sure to handle it with gloves.
