Measurement value display
In Refractive index (nD) mode, the sample measured
below the lower limit of the measuring range, or
measurement was made with air contacting the
prism.
Measure a sample within the measuring
range.
In Brix mode, the sample measured below the lower
limit of the measuring range, or measurement was
made with air contacting the prism.
Measure a sample within the measuring
range.
In Concentration mode, the sample measured below
the lower limit of the measuring range, or
measurement was made with air contacting the
prism.
Measure a sample within the specified
concentration and temperature range.
In Refractive index (nD) mode, the sample measured
above the upper measurement limit.
Measure a sample within the measuring
range.
In Brix mode, the sample measured above the upper
measurement limit.
Measure a sample within the measuring
range.
In Concentration mode, the sample measured above
the upper measurement limit.
Measure a sample within the specified
concentration and temperature range.
The alarm setting LED light comes on when the
sample measured is above the upper limit.
Measure samples within the upper limit.
The alarm setting LED light comes on when the
sample measured is below the lower limit.
Measure samples within the lower limit.
The LED light source has been depleted (in refractive
index (nD) mode).
The LED light source has been depleted (in Brix
mode).
The LED light source has been depleted (in
concentration mode).
An error is present in the connection between the
detection and display sections.
Check the connection of each section.
Turn on the power switch again.
Clean the prism.
The sample temperature measured in the Conc
mode is above the programmed range.
Measure a sample within the specified
concentration and temperature range.
※ - - - - - - is displayed during the time a measurement is being taken.
Temperature display
The sample temperature is -5.1˚C or lower.
Measure a sample within the measuring
range.
The sample temperature is 160.1˚C or higher.
Measure a sample within the measuring
range.
Flashing
temperature
value
The prism temperature is below 5˚C or above 100˚C.
In this case, the displayed Brix(%) value is not
properly corrected for temperature.
