3 - Calibraon
The accuracy can
be reached with
standard wine,
whose properes
are similar to the wine to be
tested. If no standard wine is
available, it can be replaced
by demineralized water
déminéralisée, considered as
standard wine with alcoholic
content of 0% but accuracy
will be lower.
• Rinsing
- Check that the drain valve is correctly closed.
- Rell the boiler with the standard wine to the boom of the condenser.
Then empty the boiler using the drain valve.
• Boiling point of the standard wine
- Rell the boiler to the boom of the meniscus above the red line.
- Turn on the instrument using the on/o switch.
The main screen appears.
- Let cold water circulate into the condenser, with a regular ow, not
excessive.
- Press the heang buon during at least 8 seconds to launch calibraon.
The following screen appears successively :
The heang (shown by the symbol ) lasts about 7 minutes, during which
the temperature rise can be seen on the screen.
To stop heang during the operaon, press again on the heang buon.
- When the boiling temperature is stable, the device makes a beep to
indicate the end of the measurement. Heang stops automacally.
- The boiling temperature T
Standard remains on the display.
- Match the alcohol content of the standard wine with its boiling temperature
TStandard on the disc, or use the programme «EBULLIOLOG», entering the
values «Reference Temperature» and «Alcoholic reference».
- Drain.
- Press briey the heang buon to come back to the main screen. The
device is ready for a sample measurement.
• Example
Standard wine with ocial alcohol degree = 9,2 % vol (± 0,05% vol.)
TStandard= 93,1°C
Calibrate the disc as indicated in the picture opposite.
Never turn on the
instrument using
the heang switch
when the boiler is empty or
when draining. You might
damage the instrument
if you do not observe this
rule.
The calibraon allows to measure the boiling point of a standard wine to calibrate the disk or the calcula-
on soware and inialize the atmospheric pressure sensor. This operaon must be repeated each me the
device is turned on.
i
Model 160350T with tradional thermometer :
Press the heang buon 5 seconds to launch heang. When the wine is boiling, check on the thermometer
that the temperature is stable (aer 1 to 2 minutes). Once it is stable, record the boiling temperature TStandard.
Turn o the heang using the heang switch. Adjust the disk or the programme as indicated above.
Repeat calibraon every 2 hours.
CALIBRATION

For more accuracy,
we advise you to turn
on the instrument
about 15 minutes
before use.
