Once you have assigned the VMID serial number a text, the PCE-VM 25 will display the text continually, as soon as the sensor makes contact with the measuring point
(Figure22).
Aside from this, the PCE-VM 25 reverts automatically to the saved operation mode. In this way it is ensured that measurements are always taken with the correct
settings.
Note: Changing the measuring point data also effects the display of saved measurands (cf. Chapters 6.5 and 6.6). The current saved text of the respective VMID serial
number is always displayed in the measurement data. Changing the operating mode of a measuring point only affects measurands saved subsequently and does not
have any effect on the measurands that have already been saved in the memory.
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 convenient management of measurement points.
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▼▲, until 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(Figure 23).
Figure 23: Deleting an ID record
In the same way, the entire measurement point data can be deleted as a whole by selecting “Erase all Point IDs” in the “ID Menu”. The PCE-VM 25 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, peak or crest factor display has been selected, the PCE-VM 25 always saves the
RMS and peak value. 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.
