6. HMI41 AND DATA COLLECTING
The HMI41 indicator can also be used for collecting the measurement data.
The data is stored in the indicator's non-volatile memory which means that it
is not lost when the indicator is turned off. Please, note also that the automatic
power-off function is not active during data collecting even if previously
selected (see Chapter 8.3). When the data collecting has ended, the automatic
power-off function becomes active again.
6.1 Entering the data collecting mode
Enter the data collecting mode by turning the indicator on with the ON/OFF
button. The following appears for a couple of seconds:

Release the ON/OFF button and press immediately the button HOLD. The
software version and the probe type indication appear, after which the display
changes automatically to show the battery charge:

Within a couple of seconds the text REC AUTO appears on the display; release
the HOLD button.
This is the main display of the data collecting mode. With the button MODE
you can enter the
REC CATCH mode (manual data collecting, see Chapter 6.2)
and by pressing MODE again, the REC READ mode (reading the measurement
results, see Chapter 6.5). By pressing ENTER, you can set the measurement
duration and by pressing ENTER again, the measurement interval (Chapters
6.3 and 6.4). By pressing HOLD, you can always return to the previous
display.
