Cautions for the safety
Cautions relating to explosion proof
CAUTION
・
Do not push sensor and buzzer window with pointed article.
This may cause defect or damage and correct detection cannot be performed.
・
Do not pour water on this monitor or immerse in water.
・
Do not give high impact or shock, since this is precision instrument.
・
Operating temperature range of this monitor is -20 to +50degreeC. The reading
may be affected by the sudden change of temperature if the monitor is used
under such conditions.
・
Remove the battery if the monitor is not used for a long period.
WARNING
・
Do not remodel or alter circuit/structures.
・
Replace batteries in non-hazardous area.
・
When using this gas monitor in a hazardous area, take the following
countermeasures for preventing dangers resulting from electrostatic charges.
① Wear anti-static clothes and conductive shoes (anti-static work shoes).
② For indoor use, use the gas monitor while standing on a conductive work
floor (with a leakage resistance of 10 MΩ or less).
・ Do not use this monitor except for the measurement of air and for oxygen
content measurement of gas mixtures.
WARNING
・
Perform gas calibration at proper interval.
・
Do not use unspecified batteries.
・
Check battery capacity before operation.
・
Ensure that sensor is exposed to ambient air. If not, correct detection cannot
be performed.
・
Do not modify or change the circuit or structure, etc.
・
Do not disassemble the sensor since there is an electrolyte inside. If your
finger touches the electrolyte, wash your finger with water immediately.
・
If the button is pushed randomly, each setting may be changed and alarm may
not be activated correctly. Do not operate the button other than as per
instructions.
・
Do not drop this monitor into fire.
・ Do not remodel or alter circuit, structures etc.
・ Do not use or store the unit in high temperature, high humidity or high
pressurized condition exceeding the operating conditions specified in the
specifications. Correct measurement may not be performed.
