• After a few seconds the display will show

“-0.0-”. The meter is now zeroed and ready

for calibration.

• Remove the cuvet.

• Place the CAL CHECK™ Standard HI 96770-11

Cuvet B into the cuvet holder and ensure that the

notch on the cap is positioned securely into the

groove.

• Press READ

/TIMER and the instrument status

indicator will appear, depending on the

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 HI 96770-11

Cuvets A and B are free from fingerprints

or dirt and that they are inserted correctly.

• Then the date of the last calibration (e.g.:

”01.08.2007”) appears on the display, or

“01.01.2005” if the factory calibration was

selected before. In both cases the year number

is blinking, ready for date input.
