Troubleshooting Kit; In-Line Brix Meter And Refractometer Readings Do Not Match; Brix Degree Reading Is Incorrect Or Inconsistent; In-Line Brix Meter Displays "H H H" Code - Lapierre LB User Manual

SECTION 5 TROUBLESHOOTING KIT
5.1 IN-LINE BRIX METER AND REFRACTOMETER READINGS DO NOT
MATCH
Possible cause
The refractometer (not supplied) is not calibrated to zero.
Solution
Zero-calibrate your refractometer according to the manufacturer's instructions.
Possible cause
Incorrect calibration of your In-Line Brix Meter.
Solution
Zero-calibrate your In-Line Brix Meter at operating temperature, i.e. when the temperature of the filtrate or pure
water is between 1 and 8 °C (34 and 46 °F). Refer to Sections 3.4.1 and 3.4.2.

5.2 BRIX DEGREE READING IS INCORRECT OR INCONSISTENT

Possible cause
Matter is present on the prism.
Solution
Clean the prism. Refer to Section 4.1: Prism cleaning.
Possible cause
Calibration was carried out with liquid above 8 °C (46 °F).
Solution
Clean the prism. Refer to Section 4.1: Prism cleaning.
Then calibrate the In-Line Brix Meter as described in Sections 3.4.1 and 3.4.2.

5.3 IN-LINE BRIX METER DISPLAYS "H H H" CODE

Cause
If the In-Line Brix Meter displays the code "H H H", the concentrate leaving the concentrator is above 45 °Brix,
the upper reading limit of the device.
Solution
Do not read liquids with a Brix value greater than 45.
Possible cause
You have previously calibrated your In-Line Brix Meter with filtrate or pure water at room temperature (incorrect
condition), whereas you are now operating with a cold liquid, i.e. below 9 °C (48 °F).
Solution
Re-calibrate the meter according to the instructions in Sections 3.4.1 and 3.4.2, using filtrate or pure water at a
temperature between 1 and 8 °C (34 and 46 °F) (appropriate condition).
