SECTION 4 In-Line Brix Meter maintenance and cleaning (continued)

4.2 START OF AND DURING THE SEASON

At the beginning of and during the season, we recommend calibrating the In-Line Brix Meter and cleaning the prism.
In-Line Brix Meter calibration
Calibration should be carried out at the start of the season, and every 10 days of operation. Refer to Sections
3.4.1 and 3.4.2.
Cleaning the In-Line Brix Meter prism
The In-Line Brix Meter prism should be cleaned at the start of the season, and every 10 days of operation. Refer
to Section 4.1: Prism cleaning.

4.3 END OF SEASON

It is recommended to uninstall the In-Line Brix Meter from the concentrator pipework at the end of the season
and clean it thoroughly before storing it.
WHAT YOU NEED TO PREPARE | To clean the prism at the end of the season, you'll need:
• a clean, soft cloth,
• hot water,
• ethyl alcohol (ethanol), as required,
• a clean, new, good-quality resealable bag large enough to hold the In-Line Brix Meter,
• a stable, clean surface,
- the weight and shape of the meter may make it difficult to handle during cleaning. The meter must not be
dropped or subjected to strong shocks.
IMPORTANT | Never clean the prism with an abrasive solution or cloth. Grooves on the prism will result in an
erroneous Brix reading.
To do this, proceed as follows:
• unplug the power cord (Illustration 1-d) from the In-Line Brix Meter,
• loosen the clamp connecting the plate (Illustration 2-b) to the concentrator pipe,
• place the meter on a stable, clean surface,
• clean the meter's power cord,
• clean the meter and its plate thoroughly with a clean, soft cloth dampened with warm water,
• CAREFULLY clean the PRISM with a clean, soft cloth dampened with warm water,
- NEVER touch the prism with your fingers. A fingerprint on the prism can cause material build-up and result
in an incorrect Brix reading,
- use ethyl alcohol (ethanol) if the prism is contaminated with dirt that cannot be removed with hot water.
Ethyl alcohol is available from hardware stores.
IMPORTANT | A prism must be impeccably clean, otherwise the Brix reading will be incorrect.
• Place the meter in a clean, new, good-quality resealable bag,
• store the resealable bag and power cord:
- in a dry place, away from dust, moisture and vibration,
- with a constant temperature of between 5 and 40 °C (41 and 104 °F).
