When the
○
i icon (temperature/humidity change indicator) blinks or when “0” or
“0.0” for the gas concentration value blinks, perform zero adjustment in clean air.
See page 22.
The following situation may cause zero drift (0%LEL, 0ppm
or 20.9vol% point may drift). In this case, perform zero
adjustment in clean air (page 22):

zero adjustment was performed in a gas atmosphere,
 a significant change in the work environment (e.g.,
temperature or humidity change) takes place, or
 a high concentration gas was detected.
CAUTION

Do not block any gas inlet and outlet. If blocked, normal
detection is not possible.
 Keep the filter element at the drain filter clean and dry. If
the filter element is dirty or wet, proper gas detection is not
possible.

If a reading exceeds the full scale value, move the detector
to clean air area immediately. If not moved to clean air and
continued to be used, improper gas detection will result, or
it may take time for the reading to return to the zero point.
 Do not block the audio opening. If blocked, the audible
alarm will be muffled.
WARNING
During button operation, “press” means to press the button for
less than one second, and “press and hold” means to keep
pressing the button for more than two seconds.
