Caution
When make zero adjustment, do it after having fresh air sucked into instrument
for over 1 minute.
If zero point is adjusted under presence of gas, the accurate detection can not be
carried out, and oxygen deficiency accident may be occurred.

Note
・
When desired to cancel the pre-operation, press ESC switch but after
confirmed, it can not be cancelled.

Measurement
(1)
Move the sampling tube end towards measuring point and draw gas.
-Take care not to bend and twist sampling tube.
-Check that it is drawn properly by the flowmonitor.
-Set the sampling tube end at the point of measurement, take into account the length of
sampling tube, and read out the gas concentration after getting stable of gas reading.
Danger
・
There may be the oxygen deficiency at gas outlet point due to the inert gas.
Do not breathe at all.
・
There may be the exhaust of high density gas (Above LEL).
Do not approach the fire to it.
