● Possible Causes of Issues and Corrective Actions
Issues Possible Cause Corrective Actions
Batteries does
not last long.
Continuous operation time is greatly
influenced by ambient temperature
and the sampling load.
(When using alkaline batteries,
continuous operation time at 0°C is
30-50% of 20°C.)
Use AA nickel-metal hydride batteries
(sold separately) when the load is small
and the influence of ambient
temperature is large.
(Refer to "5.1 Prepare the Power
Supply")
The flow rate
is not stable.
The flow rate
does not reach
the set value.
The pump can not control the flow
because the filter is dirty or flow
resistance is too large.
Replace the dust filter or change the
flow rate.
(Refer to “8.1 Replacing the Dust Filter
and O-ring” and “10. Specification”)
The pump
does not
operate.
The standby time may be set. Set the standby time to zero.
("6. Setting and Operations")
The power
does not turn
off.
The Power Button is disabled
during sampling, standby, or
calibration.
During sampling or standby, press and
hold the "START/STOP Button" to stop
sampling, and then press and hold the
"POWER Button" to turn off the power.
During calibration, press "MODE
Button" to cancel the calibration mode,
and then press and hold "POWER
Button" to turn off the power.
The power
does not turn
on.
・
The batteries are not installed
properly.
・
Batteries are discharged.
・
Check the polarity of the AA batteries
and set them in the battery chamber
correctly.
・
Replace the AA alkaline batteries.
・
Charge the AA nickel-metal hydride
batteries.
(Refer to "5.1 Prepare the Power
Supply")
In the Volume
Mode, the set
instantaneous
flow rate stops
lowering.
The integrated volume cannot be set
beyond 30 hours of sampling.
Lower the set integrated volume so that
the sampling time does not exceed 30
hours.
(Refer to "6.4 Volume Mode")
