Operating Procedures for GV-100S and GV-110S
Inspecting the air-tightness of the sampling pump
NOTE: When there is a leak in the sampling pump, you cannot obtain the correct measurement values
e.g. measured values may be lower than the actual values. Be sure to check the sampling pump for air-
tightness before doing any measurements. Also, check the operation of the flow finish indicator at this
time.
1)
Confirm that the inlet clamping nut is firmly tightened
2)
After confirming that the pump handle is fully in (therefore, the guide line on the pump shaft is not
seen), insert a fresh unbroken detector tube into the rubber inlet of the pump.
3)
Align the guide mark (red line) on the back plate and the guide mark (
▲
100) on the handle. At this
time, make sure that the flow finish indicator is popped out.
NOTE: When you use the GV-110 pump, align the guide mark with the guide line (red line) below
the white mark at the counter.
