to enable or disable the recording of measurements in the database, use the
field
Save log
with the use of
Time
and
Date
fields the system date and time can be set
in the
Free space
field the empty space on a removable device is shown (mi-
cro SD card)
to apply polling period and tolerances settings press
Apply
to undo all the changes press
Discard
to add/remove the devices participating in the poll and to calibrate microme-
ters enter the menu
Set etalon/Sw. State
. The top button also serves as an in-
dicator and switch modes, namely,
States
– the mode of active devices selec-
tion is active;
Etalons
– the mode of setup/reset of micrometers calibration is ac-
tive. Use the
States
function
to disable the devices that are not used in the poll-
ing during the system operation. It is necessary when the device is faulty or is
not in use, neglecting the recommendation above may cause long delays while
polling and therefore the entire system delay. The use of the
Etalons
mode is
described in the paragraph 10.3.1
to set the number of measurements used to calculate an average value use
the
Averaging
field.
10.5. Measurement journal
During operation the system generates measurement journal. To view the
measurement log enter the
Journal
menu (Fig. 13). This menu is intended for viewing
the measurements stored on a flash drive in the SQLite database file named keep.db.
Each entry has the following structure:
Time
– measurement time.
Task
– production task number.
Type
– measurement type (temperature, width, thickness).
Measure #
– number of measurement of a particular type (Corresponds to the
Index notion, described in the paragraph 10.4).
Value
– measured/calculated value.
To display the item you need use the filters:
Time range
– time range selection.
Values range
– selection of the displayed measured values range.
Task
– production task number.
Type
– measurement type (Device – value received from the device; Thickn. –
calculated thickness; Temp. - temperature).
Measure #
– number of the measurement device of a particular type.
In order to fulfill the request to display the records matching the selected fil-
ters, click
Apply
. To reset the filter values to their default values, click
Clear
. Table with
records supports vertical scrolling, sorting by columns by clicking on the table top and
row highlighting. By default, sorting is done on time: first the records that were saved be-
fore. Table records can be saved in the root of the flash drive as * .csv file. In .csv files
the columns are separated with a semicolon. Click
Export CSV
to save the file. The
name of the file includes the date and time when it was saved. After the file was saved
the message (Fig. 14) appears.
