4.1.3 Data logger

To use the data logger, the USB mode must be set to COM interface in the device settings.
You can then choose between three logger operations:
• Off
• Cyclic (= automatic logger in a set time interval)
• By keystroke (= manual logger)

4.1.3.1 Cyclic

With the cyclic data logger, measuring points can be recorded automatically at a fixed selected
time interval. The logger interval is set in seconds.
The logger can be started in operating mode by a long press of the F1 key. The word "LOG" appears
in the status line of the display during recording. After the start a folder "DATA" is automatically
created in the mass storage (e.g. 31 December 2020 19:11 \DATA\20201231\1911\). This folder
contains the parameter settings and the recorded data of all active measurement inputs as a
CSV file. No parameter settings or calibrations can be made while the logger is running. The de-
vice can no longer be switched off using the on/off button, instead the device menu is displayed.
The logger can be stopped by repeatedly pressing the F1 key.

4.1.3.2 On key press

In this mode, individual measured values can be stored manually by pressing a key. The data is
recorded in the operating mode via the F1 key, which is marked "Record". During the saving
process "Wait..." is displayed.
After data recording, a "HISTORY" folder is automatically created in the mass memory. A place
name is appended to this record, which can be selected from a list. The location designation
can be set via a COM interface command (see 4.1.2.2). Only ASCII letters and numbers may
be used as place names, no special characters. Up to 21 characters can be used and only a
maximum of 20 different locations can be defined. The designations can also be changed
directly via the mass memory. The LOCATION folder contains 20 *.LOC files which contain
the text to be displayed. This can be changed with any text editor. After making changes,
the device must be restarted.
