799 GPT Titrino
189
no method
The method required by the sample data from the silo memory
or in a TIP sequence is not available in the method memory.
Exit: .
no new com.var.
The common variable could not be assigned as the result or
the mean value could not be calculated. The old value remains
in force.
no new mean
No new mean value has been calculated as at least one
quantity stipulated for mean value calculations could not be
calculated.
no new silo result
No new silo result C24 or C25 could be stored as the assigned
quantity could not be calculated.
no new temp.var.
No new temporary variable C7X could be stored as the
assigned quantity could not be calculated.
no oven param.
The oven could not be found at the given COM.
Remedy: connect the oven to the given RS-interface of the Ti-
trino or set the following in your method under ,
>preselections, "Oven: no".
no sequence
No sequence is defined in TIP.
Exit: and define sequence.
no titration data
No curve can be printed as no data are available. With the
curves measured value vs. time or temperature vs. time, the
corresponding monitoring function must be on for the
recording of measured points.
not possible
Writing functions on the card 6.6029.XXX are not possible or
the function "empty" cannot be executed with a Dosimat.
not valid
A value is not available.
outside
The set fix volume, a fix EP or fix time is outside the measuring
range.
overrange
The measuring range of ±2 V has been exceeded. Overrange
replaces the corresponding measured value (pH, U, I or
temperature). If a measured value is in overrange (primary or
secondary measured value), the other (secondary or primary
measured value) can also be unstable.
prep.internal D0!
Warning that the preparation for the internal buret D0 has to be
executed (the warning interval is run-off).
Exit: Execute preparation with or ignore warning
with .
prep.external DX!
Warning that the preparation for the external buret DX has to
be executed (the warning interval is run-off).
Exit: Execute preparation with or ignore warning
with .
prep: manual stop
The preparation or emptying of the buret was stopped with
.
rate lim
Message in the measuring point list. A limit value of the rate
monitoring has been violated.
rate out of limit
The determination has been stopped as a limit value of the
rate monitoring has been violated.
rate too high
With DOS the calculated rate is too high. It can not be
achieved with the mounted Exchange Unit.
Exit: and use Exchange Unit with larger buret
volume or change dosing conditions.
