On the odd occasion large disturbing signals (e.g. mains spikes, lightning, etc.) can have
an adverse effect on the processor functions and hence lead to a system crash. After such
a crash the RAM area must be initialised. Although the basic instrument data remain sto-
red, the RAM initialisation should be performed only when necessary since the stored user
data (configuration, parameters, calculation variables, etc.) are cleared as a result.

RAM is tested and initialised. Subsequently a warm start is executed.
The lost data of the user memory must now be reentered.
If 'system error 3' appears in the display,
program. The initialisation values are loaded automatically. The instrument thus remains
capable of measurement. However, possibly a small loss in accuracy must be anticipated.
A new optimum adjustment can be performed by Metrohm service. The error message 'sy-
stem error 3' always appears after the instrument is switched on until this adjustment has
been performed.
