10. Measuring Brix(%)
WARNING
◇
If the unit begins to overheat, smoke, or emit an abnormal smell,
immediately turn off the power and unplug the unit from the power
supply.
If this happens, please discontinue use of the instrument and
contact an Authorized ATAGO Distributor to assist with
inspection and/or repair. Continued use may cause fire or a
malfunction of the unit.
◇
NEVER repair, modify, or disassemble the instrument. Fire,
electrical shock or burns may occur.
◇
If the instrument is dropped or receives a severe impact, DO
NOT use it and ask an Authorized Service Center to inspect it.
Continued use may cause smoke or fire.
CAUTION
◇
DO NOT measure any sample that can damage the prism or the
sample inlet unit.
◇
Cleaning liquids up to 160˚C can be used for CIP or SIP. The
momentary difference between the sample liquid temperature
and the cleaning liquid temperature must be no more than 80˚C.
When using cleaning liquids at temperatures over 160˚C, the
power source (DC24V) must be turned off. If the AD-32 (AD-33
or AD-34) is used, unplug from the outlet before cleaning.
◇
If the sample solution could potentially stain the prism,
immediately clean the prism after measurement (following the
instructions on page 36 of this instruction manual).
①
When power is supplied to the main unit, the Brix(%) measurement starts.
m
The main unit has no power switch.
②
The Brix(%) value will be displayed when sample flows onto the prism surface.
③
If there is no sample on the prism surface (only air), the error message [LL.L] will be displayed.
④
The main unit constantly detects the temperature of the prism. When the sample
temperature is within the range of 5 to 100˚C, the Brix(%) values are automatically
compensated for temperature.
N
When the sample temperature is below 5˚C or above 100˚C, the Brix(%) value
blinks.
The displayed Brix(%) value is not properly corrected for temperature.
N
When the instrument was shipped from the factory, the temperature correction
values for sucrose are set as default.
C
To change temperature correction values, see page 29
⑤
While the Brix(%) is displayed, press and hold the down
key to display the prism
temperature. For example, if the temperature of the prism is 20˚C, the display will
indicate "20c". When the down
key is released, the display will switch to the Brix(%).
N
When the temperature is in the range of 100 to 160˚C, the temperature will be
displayed as follows: "100" when it is 100˚C; and "125" when it is 125˚C.
When the temperature is in the range of -10 to -15˚C, the temperature will be
displayed as follows: "-15" when it is -15˚C.
N
When the temperature scale is °F, the temperature will be displayed as follows:
" 50" when it is 50˚F; and "210" when it is 210˚F.
⑥
For calibration (adjustment to a reference solution) see page 29.
For the setting the Recorder Output see page 34.
m
If an error message is displayed, refer to page 37 for the appropriate action.
