Ash residue XM 66
The moisture analyser XM66 can store up to four initial sample
weights ("MEMORY CHOICE ON"), which are not deleted after deter-
mination of the ash residue. As soon as the moisture analyser is swit-
ched off, the stored initial sample weights are deleted.
If "MEMORY CHOICE ON" is selected, up to four tare values and initial
sample weights can be stored.
If "MEMORY CHOICE OFF" is selected, only one initial sample weight
can be stored. In this case the moisture analyser can only be used af-
ter re-weighing is complete, as the tare weight has not been stored
.
If the mode "MODE AUTO" is activated, the final dry weight will au-
tomatically be stored as the initial sample weight for the ash residue
determination. The initial sample weight can also be entered manually.
If the "MODE MANUAL" is activated, the initial sample weight can
only be entered by starting the ash residue determination.
If "MEMORY CHOICE ON", together with "MODE MANUAL", the moi-
sture analyser can be used for other moisture determination routines
between the initial sample weight and the corresponding re-weighing
value (see chapter 5.3.5 "Configuring the ash residue program").
7.2.1 Ash residue of the desiccated samples
To ash the desiccated samples directly without transfer into another
crucible, please use "MODE AUTO" (configuration).
The tare value and the dry weight (result of moisture analysis proce-
dure) will be stored and are available for calculation of the ash residue.
NOTE
Tare the moisture analyser with an empty pan before starting the
ash residue process.
NOTE
If "MEMORY CHOICE OFF", the moisture analyser cannot be re-
zeroed between the initial sample weight and the ash determinati-
on.
