with or without
custom modules
CPU
Internal Memory
Data from 30 most
recent runs
Max. of 40 measure-
ment protocols

Memory structure
The internal memory contains the instrument and configuration
parameters, as well as the measurement protocols and data from
the 30 most recent runs. Part of this memory is used as a working
memory for measurements and evaluations.
Storage security
A maximum of 40 measurement protocols can be created by the
user, and these are stored in the instrument’s internal memory
independent of current and battery, as are the instrument and
configuration parameters. Therefore, these can only be lost if the
CPU develops a fault, or similar.
In the event of a power failure, the data from the 30 most recent
runs are stored in a battery-backed memory for at least 3 months.
