᭜ For the safe use of this equipment
WARNING
Requirements for explosionproof use:
The ambient temperature is in the range -20 to +55
ЊC. The surface temperature of the
ZR202S is not over the temperature class T2 (300
ЊC)͓note 1͔
* The surface temperature of the amplifier box does not exceed 70
ЊC.
CAUTION
The cell (sensor) at the tip of the probe is made of ceramic (zirconia element). Do not
drop the equipment 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 leakage of the gas. If there is any leakage of the gas, the moisture drawn
from the measured gas may damage the sensor.
• The probe (especially at the tip) becomes very hot. Be sure to handle it with gloves.
