Calibration
<Caution> The initial calibration is executed at SENSOTRAN S.L. before device shipment. The calibration
values are saved in the device which means inaccurate calibration may impair the accuracy of the device
performance. User should perform calibration every six months.
<Caution> Because it is calibrated on the assumption that oxygen concentration is 20.9%vol, the combustible
gas is 0%LEL, and the toxic is 0ppm in the normal fresh atmosphere, fresh air calibration must be conducted
in the absolutely clear air without any impact of other gases.
Fresh air calibration in the airtight spaces
therefore is not recommended. Make sure to avoid calibration under the work environment where gases may
be present.

Fresh Air Calibration
Press KEY button ( ) for 3 seconds under the gas calibration value mode and the icon ( ) for fresh air
calibration will appear on the display with the message “CAL ZERO.” Press for another 3 seconds to do fresh air
calibration and it will take 10 seconds to calibrate. Press the button during the calibration process to abort the
calibration. If you press the button upon the completion, it will return to the fresh air calibration mode, and if
you don’t press the button, it automatically enters the measure mode.
If the calibration fails, message FA(Fail), appears on the display. Press the button to enter
the initial fresh air calibration mode and it changes into the measure mode if you do not press
the button for 3 seconds. If FA continues, please consult SENSOTRAN or your local
distributor as it may require the replacement of the sensor or maintenance tasks.
