7.7 Measurement Data Recording
The multimeter offers the option of saving measurement data
once by pressing a button or repeatedly as a measurement series
over longer periods of time.
Data are stored to a battery-backed memory module, and are
retained even after the multimeter is switched off. The system
acquires measured values relative to real-time.
Note
Measurement data recording is ended automatically as
soon as internal memory is full.
No measurement data are overwritten. Memory has to be
cleared in order to record further measurement data (see
page 23).
Stored measurement data can be read out via Bluetooth . See
also interface operation in section 9 on page 56.
Refer to section 7.6 on page 20 concerning storage of current
data to IZYTRONIQ software.

7.7.2 Measurement Series (automatic storage)
Recording type must first be set to “Periodic” for measurement
series, and several basic parameters have to be set, for example
the sampling rate.
Note
Consider available memory space when selecting your
settings (see page 23).
Afterwards, you can start memory mode operation and then the
measuring function at any time.
The general procedure is described here first, and the following
subsections explain the respective parameters and their configu-
