OUT CAL RANGE FUNCTION
The instrument has an
Out Cal Range
function to
prevent taking measurements in a range where the
calibration does not assure the best results. The range
where the calibration assures correct measurements
is up to 40 FNU for two‑point calibration and up
to 150% of the third point value for three‑point
calibration.
The display will show a blinking “CAL” tag each time
the measurements are taken outside the calibration
range.
CALIBRATION ERRORS
• If the read value during calibration is too far from
the set value, the instrument will show “‑LO‑” or
“‑HI‑” error.
• If the calculated calibration coefficients are
outside a certain range, the “CAL Err” message
is displayed.
CALIBRATION DELETION
HI98713
is factory calibrated. It is possible to delete
last performed calibration.
To delete last calibration, follow the next steps:
• Enter the GLP feature by pressing GLP .
The date of the last calibration will be displayed
on the LCD.
• Press READ to see the information related to
calibration. The last panel is the one with delete
calibration.
• Press SETUP/DEL to delete the current calibration.
After deletion the instrument will automatically
return to measurement mode.
• Close the lid and press READ . The display will
show blinking dashes and the icons for cuvette,
detectors and LED will appear during measure‑
ment.
• At the end of the measurement, the four‑point
calibration is completed and the instrument
returns automatically to measurement mode.
