If the unit is going to be operated in adiabatic mode, an adjustment is required first.
This has already been performed at the factory during the functional test. Under
normal laboratory conditions, the user must perform an adjustment again if:
•
Measurement times for adiabatic measurements regularly take longer than 25
minutes.
•
Adiabatic measurements are frequently interrupted because the time limit for the
preliminary or the main experiment has been exceeded.
Procedure for an adjustment:
•
Set the operating mode to
$GMXVWPHQW
(see Section 8; Item 8.8
6\VWHP
VHWWLQJV
). For a duo-control unit, this setting refers to both measurement cells.
•
Prepare a mock measurement (see Section 10, Item 10.3). An empty crucible is
used. Enter the fictitious value “1” for the weighed in quantity.
•
Start the measurement.
•
The process completes itself automatically within 72 to 120 minutes. Upon com-
pletion, a value D = ….. is displayed in the result window. You should make note
of this value in your device materials. In this case the adjustment was success-
ful.
Then switch back to the desired operating mode. If you would like to work in adia-
batic mode, the
FDOLEUDWLRQV
must be
UHSHDWHG
for all decomposition vessels.
If the adjustment is not successful within 120 minutes, the procedure is interrupted
without any result.
In this case, please contact your Technical Service Department.
