Errors and Warnings
Out of Range: The sample is out of the measurement
range. Check to make sure you use the sealed glycerol
reference cuvette to calibrate the meter before taking
a measurement.
Inverted Cuvette: The glycerol reference cuvette and
sample have been inserted in the wrong order. Otherwise,
check if the cuvette has been inserted upside down.
Low Battery: The battery is low and must
be replaced soon. Normal operation of the
instrument will not be interrupted.
Dead Battery: The battery is dead and must be
replaced. Once the battery display is flashing, normal
operation of the instrument will be interrupted.
Change the battery and restart the meter.
Light High: There is too much light to
perform a measurement. Please check that
the cover is fully closed, and that the glycerol
reference cuvette was used properly.
Light Low: There is not enough light to perform a
measurement. Check to see if the light is blocked or
dirty. Do not use a syrup sample to calibrate the meter.
Error: Internal error. Please contact your
local Hanna Customer Service Center.
