If you are using the GV-110S pump with a counter, please follow the instructions on page 9.
4)
Direct the tube end to the point of measurement and pull out the handle fully (for 100ml
sampling) or halfway (for 50ml sampling) along the guide line to the lock position.
NOTE: If you are using the GV-110S pump with a counter, do not grasp the counter, otherwise the
counter will not operate properly and may result in a malfunction.
5)
Wait until the specified sampling time has elapsed. The completion of the sampling of 100ml or
50ml can be confirmed by the flow finish indicator on the handle. Unlock the handle by turning it
more than ¼ turn and restore it to the initial position.
When the pump handle is pulled out, the white indicator of the flow finish indicator is pulled in by
vacuum generated in the pump cylinder. It pops out when the prescribed volume (100ml and
50ml) has been fully sampled.
The time necessary for one sample is shown in the operation insert of each pack of detector
tubes.
Repeat the above steps if one or more pump strokes are required.
