6. Saving, retrieving and deleting results
•
The results of each successful measurement are stored
together with date and time. With more than 30 items of
measured data, the earliest items of data measured are lost.
•
Use the SET button and then the -/+ buttons to select the
desired user memory and confirm using the button
. Pres-
sing the M+ button displays the average value AVG of the 3
most recent measurements stored in the user memory. By
pressing the + button, the most recent measurements are
displayed; by pressing the - button, the oldest are displayed.
•
The average value AVG can only be displayed if there are 3
saved values in the respective user memory.
•
To clear the memory, you must first select a user memory.
Hold the SET button pressed for approx. 3 seconds. All the
values in the current user memory are deleted after 3 brief
beeps are output.
•
If you wish to change the user memory, see “Select memory”.
