Each recorded measurement gets a consecutive number. The next available number is displayed
in the upper left corner as “Mxxxx” (see Figure 10).
If the memory is full, a message “Data memory full.” appears after pressing the SAVE key.
The available memory space can be checked by the ◄ (INFO) key during measurement.
Occupied memory is indicated as a black bargraph.
To erase the entire data memory, press MENU and go to “4/8: Erase memory”. An empty

12.2. Automatic Recording in the Data Logger Mode
After selecting the data logger mode in the menu “2/8: Recording setup” you are asked to select
a time unit. Using the ▲▼ keys you may choose between seconds, minutes or hours. After
pressing OK you may enter a time interval between 1 and 9999 using the ◄▲▼► keys. In the
next step you enter the log duration. It must be longer than at least one log interval. Otherwise
an error message will be displayed. If you confirm the preset value “0000”, the maximum log
duration of 10 000 seconds, minutes or hours will be used. In the last step enter a name for the
log file using the ◄▲▼► keys. It may consist of up to 20 capital letters and numbers. Now the
settings for the data logger functions are complete.
The logger is started by the SAVE key. First the log interval, the log duration and the available
memory are displayed for your information. Confirm by pressing OK. Should the VM30-H
memory still contain manually saved data, a warning will inform you that this data must be
overwritten.
Data logger operation can be recognized by the increasing record number “M0000” in the upper
left display corner. While the data logger is running, the MENU, RANGE and LOAD keys are
disabled. When pressing one of these keys or the ESC key, a message “Logger halted.“ appears.
You may resume logging by OK or finish by ESC.
The VM30-H can hold several independent log files in its memory. A new log file can be
appended by pressing the SAVE key again. Before saving a new log file, you can also change
the settings in the menu “2/8: Recording setup” if desired.
It is useful to lock the keys of the VM30-H when it is in the log mode to avoid interruption by
accidental key pressure. Press the LOCK key and confirm by OK. Now all keys are disabled. To
unlock, press the LOCK key again and confirm by OK.
To delete the entire memory, select the menu function “4/8: Erase memory“. An empty memory
can be recognized by the record “M0000”.
12.3. Viewing Saved Measurements on the Display
