6.3.3. Editing and Deleting Measurement Point Data
Open the main menu by pressing F3 and select the sub-menu “Point ID memory” by
using keys ▼▲.
Within the menu option “Edit Point ID”, as previously explained in section 6.3.2,
the measurement point texts and the operating mode allocated to the measuring
point can be changed. In the sub menu “Edit Point ID” press or hold down▼▲, un-
til the text you wish to edit is displayed and then press OK to edit.
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 ▼▲, until
the record you wish to delete is shown, then press OK and confirm the warning by
pressing OK again(23).
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 VM24 memory can store data
for a maximum of 1600 measurement points.
Note: Deleting measurement point data effects the display of saved measurements.
(chapter 6.6). Instead of the measurement point serial number and the measurement
point text being shown, “none” is displayed. The measurement point data records
can always be newly generated, as described in 6.3.2.
6.4. Saving Measurands
Pressing the ▼ key saves the currently displayed measurand. Independently of
whether RMS or peak display has been selected , the VM24 always saves both val-
ues. Furthermore the respective measurement point number (if known), the chosen
display mode and the date and time are also saved.
Note: If the sensor locates a measurement point which has not yet been assigned a
text or operational mode (cf. Chapter 6.3.3), use the ▼ key to enter the text.
From Version xxx.021: If the sensor is not placed on a VMID measurement point
while saving you will be prompted to enter a description of the measurement with
up to eight characters.
