CALIBRA
TION PROCEDURE
• 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™ Standards
HI96720-11 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.
