METTLER TOLEDO DE40/50/51 Density Meter 43
10. Functions (password protected)
10.1 Data File (Function 0)
This function allows to view and process the measured data. You can either do a
recalculation of measured results, statistics on the results or delete single data i.e. mark
them so that they are not considered in the statistics calculations. You can also save these
measured data on a Data Memory Card or load them from such a card for recalculation.
Select Function "0.Data File" and
confirm with <ENTER>.
The measured data are displayed,
together with the method and result
type:
- d : density
- dt : specific gravity (d(t/t)
- d4 : specific gravity (d(t/4)
- C : concentration
- Br : BRIX
- Al : ALCOHOL
Now select with the and keys between <Statistics>, <Recalc.>, <Load> and <Save>
and confirm with <ENTER>.
Note 1: If you have many data stored, press 0 to display the first 4 data (0 to 3), and 1 to 9
to display the next blocks of data (10 to 13, 20 to 23, ... 90 to 93).
Note 2: The <Load> and <Save> options require a Data Memory Card. These options are
described separately in section 12."Data Memory Cards".
10.1.1 Statistics
The function allows to process and view the measured data statistically. You can calculate
the mean value (Mean), the standard deviation (SD) and the relative standard deviation
(RSD). The relative standard deviation is the same as the coefficient of variation (CV).
The measured data can be filtered so that useful statistical results can be obtained after a
days work. On the first level the method will give access to the respective data only. On the
second level the series number (first two-digit number of the sample number) can be chosen
for which the statistics is to be done.
Note: If too many filters are activated it is possible that all results are excluded.
