Statistics And Memory - ANDILOG CENTOR EASY Operating Manual

5. Statistics and memory

The Centor Easy has a mode called "Statistical" allowing to perform a series a measurements and get
quickly the mean and standard deviation.
a. Limitation
The memory of the force gauge is limited to 100 measurements; beyond it will be necessary to clear
the first results to be able to add new ones.
b. Access
Access to this mode by: pressing "M" button, moving the cursor down to reach the line called
"STATS" and entering the sub-menu by pressing the right arrow TDX button.

d. Possible actions
If no data are saved, you can configure the three parameters described above. To do so place the
cursor on the parameter and change the settings with the left and right button
If data are saved, you can:
•
Review the result, moving the cursor in the table: up and down keys
•
Delete the selected sample or the entire series: left button (ZERO)
•
Send data : right button (TDX)
If no action has been carried out on SATS submenu, the screen allows you
to configure three parameters:
•
Mes/Samp: Number of measurement per sample
•
Oper: Personal ID number of the operator
•
Unit: Measurement unit
If measurements are saved in the memory, those three parameters are
no longer available. The only way to access it again is by clearing the
memory.
If measurements are saved, they are displayed at the bottom of the page,
the cursor can move in the table.
The displayed data are as follow:
•
The first number indicated the sample number, the second
number is the measure itself
•
If your samples contains more than one measurement (see
parameter (Mes/Sample) so you have multiple rows with the
same sample number
Also 3 statistical calculations are displayed:
•
Mea: Average of the series of measurements
•
StDev: standard deviation of the series of measurements
•
S/M: Standard deviation divided by the average
