Symptom Possible Cause Corrective Action
Battery does not charge The unit must be turned on but not in
sampling mode for the battery to charge. Turn on unit. Green LED by on/off button
should be lit.
Unit is actively taking data. The unit will not recharge the battery
while taking a measurement. Once the
measurement is complete, the unit will
begin recharging the battery.
Unit not put in standby mode when turned
off. Select Standby/Charge when shutting off
the instrument if you want the battery to
be charged.
BATTERY ERROR Low battery (<10%). Recharge battery or connect AC cord.
Single battery in 100 L/min Model 9500, or
two batteries where one has been only
partially charged The 100 L/min Model 9500 requires two
batteries (within 25% charge of each
other) to take a sample. If only 1 battery
is installed, then the unit will not start a
measurement and will display the battery
warning. To correct, place a second
charged battery in the instrument.
FLOW ERROR Instrument was unable to control flow rate
[i.e., if sample tubing used is too long
(greater than 12 m on 28.3 and 50 L/min
instruments, 8 m on 100 L/min instrument)]. Restart measurement.
Pressure drop across inlet may be too
large. Lower pressure drop across inlet by
using larger diameter tubing, less tubing,
and/or adding a bleed valve.
