• After a few seconds the display will

show “-0.0-”. The meter is now zeroed

and ready for calibration. The blinking

“READ” asks for reading calibration

standard.

• Remove the cuvette.

• Place the CAL CHECK™ Standard

HI 96702-11 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™

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 96702-11 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.
