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 FTU 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
HI 98713 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
cuvet, detectors and LED will appear during
measurement.
• At the end of the measurement, the four-point
calibration is completed and the instrument
returns automatically to measurement mode.
