The grid can have a maximum of 52 columns and 999 rows
4. Set the Auto Increment direction. This option allows you to select which direction the cursor
moves after a reading is stored in terms of compass points. For example NORTH would move
the cursor up a row, and WEST would move a column left.
5. Choose whether to activate SAVE GRAPHICS or not (snapshot of the A OR B scan on
screen).
6. Finally create the log by scrolling to CREATE LOG, pressing ENTER and then OK to confirm.
The measurement grid is now displayed along with the grid name on screen.
13.3 HANDLING LOGGER FILES
Once created, logger files may be opened or closed using the functions "OPEN" and "CLOSE"
Closing logger files places the gauge in immediate mode and will prevent accidental saving of data
into an inappropriate log.
13.4 STORING READINGS IN A DATA LOGGER FILE
1. Create a new data logger file or open an existing file.
The grid is displayed in the lower half of the measurement screen.
Note: Once the file is open, it will remain open until it is closed or another file is opened. If the
gauge is switched off, the file will be opened automatically when the gauge is switched on
again. Press the ENTER key to display the file from the measurement screen.
2. If you want to save the reading to a particular cell location, scroll to the desired cell.
Note: The cell location must be empty. If it already contains a reading and you want to save a
new reading to the same location, refer to the instructions given in 'Viewing and Deleting
readings" on page 18.
3. Take a reading and then press ENTER.
The reading value is saved in the file at the location selected and the cursor advances to the
next cell according to the rules set for the data logger file:
•
If INCR. DIR is set to NORTH, EAST, SOUTH or WEST, the cursor will advance one cell in
the chosen direction. When the cursor reaches the last cell in the row or column it will
return to the other end of the row or column.
Note: If you try to save a reading into a cell location which already contains a reading value, a
warning message is displayed (see Deleting a reading).
4. To advance to a specific row number, press OK enter the row number. Press OK to advance
directly to that row number in the grid log.
5. To toggle the display between DIGITS view and B-SCAN view, press ESC.
6. If you are unable to take a measurement due to the measurement location being physically
inaccessible, press CLR.
The cell location in the data file is marked OBST (Obstruct).
7. The display of the log data file on the measurement screen can be switched on and off:
•
To switch off, press MEAS
•
To switch on, press ENTER.
13.5 VIEWING AND DELETING READINGS
With a data file open:
1. Use the arrows to scroll through the cells in the data file.
As the cursor is moved to a different cell, the display is updated with the display view saved
with the reading (if SAVE GRAPHICS was set to YES). Readings stored in memory are
indicated by MEM in the top left corner of the measurement screen (in place of the bars of the
stability indicator).
