All statistics data can be switched
on by pressing the “result on/off”
button.
act = Last measured value; in
Continuous Mode, this is the value
for the inserted specimen
m = Mean value
min = Minimum value
max = Maximum value
s = Standard deviation
v = Variance coefficient
When the statistics function is
active, the measured values are
saved and retained when you switch
to a different parameter or switch off
the instrument. The saved values
can be transmitted to a printer or PC
via the serial interface. A previously
saved measurement series can be
called up again and continued if it
has not been deleted. It is not
possible to change calibration
values while a series is running, as
this would falsify the statistical
results.
8.2 Statistics with Continuous
Mode
In Continuous Mode, measurements
are displayed continuously but they
are not saved automatically. To add
a measurement to the measurement
series, it is necessary to press the
“operate” button.
8.3 Deleting One Measurement
The “delete last” button
deletes the last saved
measurement.
The counter variable “n” is
decreased by 1.
8.4 Deleting All Measurements
The “delete last” button
deletes all measurement
in this series.
The deletion function only
relates to the parameters
currently set in the memory
area.
