show “-0.0-”. The meter is now zeroed

cuvette and detector icons will appear on

measurement phase.
• After measurement the instrument will
show for three seconds the CAL CHECK™
Standard value.
Note: If the display shows “STD HIGH”, the
standard value was too high. If the
display shows “STD LOW”, the
standard value was too low. Verify
that both CAL CHECK™ Standards

Cuvettes, A and B are
free from fingerprints or dirt and that
they are inserted correctly.
• Then the date of the last calibration (e.g.:
”01.08.2009” ) appears on the display,
or “01.01.2009” if the factory calibration
was selected before. In both cases the
year number is blinking, ready for date
input.
