EXAxt ZR is very heavy. 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 process 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

CAUTION
The cell (sensor) at the tip of the probe is made of ceramic (zirconia element). Do not drop the equip-
ment or subject it to pressure stress.
• Do NOT allow the sensor (probe tip) to make contact with anything when installing the analyzer.
• Avoid water dropping directly on the probe (sensor) of the analyzer when installing it.
• Check the calibration gas piping before introducing the calibration gas to ensure that there is no
