chosen. Each stage can run at a unique temperature.

w
for DVS determines the
and consequently the resolution. A step setting of

0.1, 0.2, 0.3 ... up to the final
level until either equilibrium is achieved based on
the trigger value or the timeout value is reached.
Setting a higher value will make the test faster, but

To choose the trigger %dm/dt value that will indicate
equilibration, press enter with "Trigger" highlighted
and then cycle to the desired value using the up and
down arrows. The trigger can be shut off or be any
value between 0.001-1%/hr. Choose the number of
events required to meet the trigger value. The trigger
value represents an acceptable change in mass per
change in time to indicate equilibrium for a given step.
Setting a higher value will make the test faster, but
may not result in complete equilibrium. If the trigger
is turned off, the sample will be held at each step for
the time indicated by the timeout setting.
•
To choose to include a timeout setting, press with
"Timeout" highlighted and then cycle to the desired
value using the up and down arrows. Any value
between 5.0 min to 30 days can be selected. The
timeout determines the maximum time allotted for
a
each
step NOT the time from starting
w
a
. The default value is off, which means there is no
w
timeout value and only the trigger value will
determine the end of step. If both a trigger value and
timeout value are set, whichever is reached first will
determine the end of the step.

4. Lightly tap the table with one finger. If the
readings vary more than 0.2 mg after tapping,
the table is probably too unstable for accurate
weight readings during a test and will need to be
made more rigid or another location found for
this equipment. Contact your AquaLab
distributor if the scale readings are unstable after
placing the unit on a stable structure.
Desiccant Cartridge
Desiccant Receiver
Black Valve
Black Receiving Hole
Figure 2: Desiccant installation
• Desiccant tubes are installed by orienting the tube so that
the black colored valve inserts into the black receiving hole
as shown in Figure 2: Desiccant installation. Before insertion
make sure that the desiccant tube lid is firmly sealed onto
the desiccant tube. (See Manual for instructions) Lift the
tube into the area above the desiccant receiver and then
insert the tube into the mating holes while shaking the tube
slightly. Once in place, the desiccant tube is sealed for flow
purposes and may move side to side if contacted.
