Standard Gas Calibration
icons shall blink when arrow key is pressed for 3 seconds under the state power key is
pressed simultaneously.
icons shall blink when arrow key is input at this state. Standard gas
calibration is initiated by pressing power key for 5 seconds at this time. Please be careful not to
process calibration under the state that standard gas is not connected.
Caution : As the calibration is conducted under the assumption that the concentration of
oxygen in fresh air is 29.9% and that of flammable gas is 0%LEL and the same of toxic gas is
0ppm, the fresh air calibration must be conducted in fresh air where no influences of other
gases are effective. Hence, it is not desirable conducting fresh air calibration in a closed
space and should be very careful not to conduct under the working environment where
gases can be inhaled by workers or operators.
Once standard gas calibration is initiated, calibration shall be processed during the
countdown for 20 seconds. In case calibration is normally processed, the
icons shall blink
with alarm sound and the concentration value of the gas connected for the moment shall be
indicated. After then, when the connection of standard gas is blocked, the value of
concentration measured for the moment shall be indicated. In case calibration is failed, it will
return to Gas Measure Mode with alarm sound after the
icons being blinked for 3 seconds.
In this case,
icons shall not be disappeared but kept appeared. If such occurrence happens
repeatedly, please make inquiry with our agent or A/S center as the sensor is required to be
replaced.
