Troubleshooting 6-3
Symptom Possible Cause Corrective Action
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.
Inlet tubing kinked. Straighten tubing.

pressure. Do not subject the unit to
other than ambient
