• After a few seconds the display will show
“-0.0-” . The meter is now zeroed and ready
for calibration. The blinking “READ” asks for

• Remove the cuvette.
• Place the CAL CHECK TM Standard HI 96700-11
Cuvette B into the cuvette holder and ensure that
the notch on the cap is positioned securely into
the groove.
• 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 96700-11 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.:
”01.08.2009” ) 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.
