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

groove.

/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.
