All parameters changed by the operator are marked automatically so
thattheycanveriedinthenextstep.
ForthevericationthePINmustbeenteredrstandacomparisonof
twocharacterstringsmustbecarriedout.Theusermustconrmthat
both character strings are identical, this is used to check the charac-
terrepresentationandthecommunicationchannels.Theverication
texts are provided in German and with all other menu languages in
English.
Inasecondstep,allmodied,safety-relevantparametersarelisted,
whichmustallbeconrmed.Afterthisprocessisnished,theinstru-
ment will be locked automatically and the safety function is guaran-
teed again.
Warning:
If the described process was not carried out completely or correctly
(e.g. due to interruption or voltage loss), the instrument remains in an
unlocked, and thus unsafe, status.
Warning:
In case of a reset to basic settings, all safety-relevant parameters will
also be reset to default. Therefore all safety-relevant parameters must
be checked or readjusted.
