Altering display contrast
• The contrast of the LCD display can
be altered with the arrow keys <>
and <> during the measured val-
ue display.
• This setting is retained after the in-
strument has been switched off and
on. The default value is only reset af-
ter the memory has been initialized.
Controlling the menu bar
• In each menu display the <> und
<> keys can be used to move the
selection bar up and down by one
line.
Cursor control for text input
• The character to be entered is se-
lected with the arrow keys and en-
tered with <OK>.
Leafing through the measured value
memory
• Leafing through between the entries
in the measured value memory dis-
play: starting from the last measured
value having been stored you can
access older entries with <> and
vice versa.
Calibration
• The calibration sequence is contin-
ued with <OK>.
• The calibration data are accepted
with <OK> in case they are out of
the defined limits.
Confirming entry
• The <OK> key is used to complete
each entry with the selection bar
moving on to the next parameter. If
an entry is exited without this confir-
mation then the entered value will be
rejected.
