Managing the Datalogger File System
The TKG150 supports the following two files types:
Linear file
: Consists of ID# from 0001 to
5000. The extended memory option consists of
ID# from 1 to 500000.
Grid file
: Consists of ID# as COLUMN and
ROW. The COLUMN is single or double digit
capital alpha character from A to Z and AA to
ZZ. The ROW is a four digit number based on
the 5000 / COLUMN.
For example, when you create a new GRID file with
END COLUMN = C, then the maximum ROW you can
slew up to is limited to 1666 calculated by the instrument
as follows:
The total storage space per file is 5000 readings.
For Columns ending at C, this means 3 columns
are required and the maximum Row allowed is
limited to 5000 / 3 = 1666.
If you create a new GRID file with END COLUMN =
Z, then the maximum ROW you can slew up to is limited
to 5000/26 = 192.
If you create a new GRID file with END COLUMN =
AF, then the maximum ROW you can slew up to is
limited to 5000/(26 for A to Z + 6 for AA to AF) = 156
the grids are created as shown below:
