Control Functions
During Recording
STORE is displayed underneath the analog display during memory
mode operation, and
memory occupancy
can be controlled:
StoP
000.3%
The following message appears as soon as memory is full:
“100.0%”.
In order to be able to observe measured values during recording,
switch to the measuring function by pressing MEASURE | SETUP.
The display is returned to the memory menu after once again
pressing MEASURE | SETUP.
A new memory block is created when another measuring function
is selected with the rotary switch or the FUNC | ENTER key. Data
storage then continues automatically.
Ending Recording
➭ “StoP ” appears at the display after pressing MEASURE | SETUP.
StoP start
➭ Acknowledge the “StoP ” display by pressing FUNC | ENTER.
STORE is cleared from the display, indicating that recording has
been ended.
➭ Press MEASURE | SETUP in order to return to the measuring
function.
➭ Memory mode operation can also be exited by switching the
multimeter off.
Querying Memory Occupancy
Memory occupancy can be queried during recording with the
help of the “1nFo ” menu (see also chapter 6.3).
Memory occupancy range: 000.1% to 099.9%.
