Note: Changing the measuring point data also effects the display of saved measur-
ands (cf.  Chapter 7). The current saved text of the respective VMID series number
is always displayed in the measurement data. 
The measurement point data is saved in the instrument. If several instruments are
used at the same measurement point location, the measurement point data will need
to be saved within each instrument. The available PC software enables the conve -
nient management of measurement points.

6.2.3. Deleting Measurement Point Data

Remove the sensor from the measurement point  and open the main menu by press-
ing F2 and select the sub menu “Point ID memory” by pressing F1 and OK.
Within the menu option “Erase Point ID”, measurement point data records, each
consisting of a VMID serial number, text and operational mode, can be deleted one
by one. In the subsequent menu “Erase Point ID”, press or hold down F1 until the
record you wish to delete is shown,  then press OK and confirm the warning by
pressing F1 once again. (18).

In the same way, the entire measurement point data can be deleted as a whole by se -
lecting “Erase all Point IDs” in the “ID Menu”. 
The VM22 memory can store data for a maximum of 1600 measurement points.

Note: Deleting measurement point data effects the display of saved measurements.
Instead of the measurement point series number and the measurement point text be-
ing shown, “none” is displayed. The measurement point data records can always be
newly generated, as described in 6.2.2

6.3. Saving Measurands

The currently displayed measurands and their measurement point numbers (if avail-
able), as well as the date and time can be saved by pressing the F1 key.

Note: If the sensor locates a measurement point which has not yet been assigned a
text (cf. Chapter 6.2.2), the F1 key can be used to enter the new measurement point
text.
