Up to 30 events may be saved and when the list exceeds 30, the oldest data will be automatically
deleted. The saved data can be checked when transmitting it to PC through SENKO IR-LINK.
Data log records the operation status every second and normal data logs do not last more than 2
months.

5. Calibration
Caution!
The initial calibration is executed at SENKO CO. Ltd. before device release. The
calibration values are saved in the device which means inaccurate calibration may impair the
accuracy of the device performance. Normally, the calibration should be done once a year after the
purchase and regularly every six months thereafter.
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 operation
under the work environment where people may inhale gases.
5.1. Fresh Air Calibration
Press KEY button
for 3 seconds under the gas calibration value mode and the icon (
)
signifying fresh air calibration will appear on the LCD monitor with the phrase
“CAL ZERO.” Press for
another 3 seconds to do fresh air calibration and it takes 10 seconds to calibrate. Press the button
during the calibration process to stop 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, FA(Fail), not OK, appears on the LCD. 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 SENKO
or the store you purchased as it may require the replacement of the sensor or repair
of the device.
