REASONS
there is a corruption of
the configuration data
in the memory of the
instrument
• the kind of top probe
you have connected
is not right
• the top probe plays
up
• the connection in-
strument-top probe
is wrong
• the top temperature
is outside the limits
allowed by the work-
ing range of the in-
strument
MEANING
REMEDIES
turn OFF the power
supply of the instru-
ment: unless the alarm
disappears, you will
have to change the in-
strument
• look at parameter /0
• test the integrity of
the probe
• test connection in-
strument-probe
• test the temperature
close to the probe
EFFECTS
• the access to the set-
ting procedures will
not be allowed
