Integration
Error
●
When timer mode
If the measured
integrated value falls out
of ±5% of the value
calculated from
multiplying the set
sampling time by the
flow rate, the error
message is displayed
after the pump stops
●
When Volume Mode
If the actual sampling
time is out of ±5% of
the value calculated
from the set integrated
value and flow rate (In
intermittent operation, if
calculated sampling
time + 1 minute is
exceeded), the error
message is displayed
after the pump stops.
※Not applicable if
sampling is stopped
with "Start/Stop Button"
The flow rate may not reach
the set value due to a large
resistance of the sampling
media.
Check if the flow resistance of
sampling media at the set flow
rate is within the
specifications of the pump.
(Refer to “10. Specifications”)
