CHAPTER 6
COLLECTING DATA
The HMI41 indicator can be used for collecting the measurement data. The data is
stored in the indicator's non-volatile memory; 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. When data collecting has
ended, the automatic power-off function becomes active again.
Data collecting modes
The following three modes are used when collecting data:
- REC AUTO : automatic data collecting
- REC CATCH : manual data collecting
- REC READ : reading the measurement results
Entering the data collecting modes
Turn the device ON (by using ON/OFF button) and immediately (within 1..2 seconds) after
turning on press immediately the button HOLD for at least 5 seconds. The software version
and the probe type indication appear for a second, after which the text
REC AUTO appears on
the display; then release the HOLD button.
REC AUTO is the main display of the data collecting mode. With the button MODE you can
enter the REC CATCH mode (manual data collecting, see page 24) and by pressing MODE
again, the REC READ mode (reading the measurement results, see page 25).
