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 NTU 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.
