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 initialized. Although the basic instrument data remain stored, the
RAM initialization 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 initialized. 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, can be used to return to the instru-
ment program. The initialization 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 'system
error 3' always appears after the instrument is switched on until this adjustment has been
performed.
