• Press READ/ /TIMER and the lamp, cuvette
and detector icons will appear on the display,
depending on the measurement phase.
• After measurement the instrument will show for
three seconds the CAL CHECK TM 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
TM
Standards HI 96750-11 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.:
”01.08.2008” ) appears on the display, or
“01.01.2008” if the factory calibration was
selected before. In both cases the year number
is blinking, ready for date input.
