4.3 Initialise and test RAM
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
stored, the RAM initialisation should be performed only when necessary since the stored
user data (configuration, parameters, calculation variables, etc.) are cleared as a result.
• Power OFF
• Power ON and simultaneously press keys <DOS> and <STOP/FILL>.
RAM Init.
• Press <START>.
confirm RAM Init.
• Press <START>.
RAM Init. activ
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, <Clear>can be used to return to the instrument
program. The initialisation values are loaded automatically. The instrument thus remains
capable of measurement. However, possibly a small loss in accuracy must be antici-
pated. A new optimum adjustment can be performed by Metrohm service. The error mes-
sage 'system error 3' always appears after the instrument is switched on until this adjust-
ment has been performed.
