DATA LOG FUNCTION (OPTION)
The device has a data log function. A memory card may be used as data logger. All measurement values will be saved,
separated by tabulators, in a text file. The time interval may be adjusted from 1-4294967 s (= 71 minutes). To activate
the data log function, a memory card must be inserted. The root directory of the memory card must contain a text file
named “EPSLOG.txt“. The new data will be written into this file.
The memory card must b e ins erted o r remo ved in st an dby
mode only!
In case, that the first entry of the first line of the file is "interval=xxxx" (xxxx = time in seconds), the memory interval is
adjusted accordingly. The entry must be written in lower case letters and without space characters. If the interval
remains unspecified, the memory interval is 60 seconds.
Example:
interval=30
The data log function is active whenever the device is not operating in standby mode. The function is indicated by a
small memory card symbol in the upper right corner of the main display. Whenever a new data set is written, the
symbol will be displayed as filled for ca. 1 second. In case the memory card is full, the symbol will be crossed out.
