After the completion of the first measurement, a series of similar messages will follow with instructions for
the laboratory assistant (user) until the complete completion of the calibration procedure, which will be
announced by the following message:
If you have a printer connected to the device and you have selected it (see item 5.4.6.5), the measurement
results will be printed automatically.
Printout example:
5.4.5.2. Alcohol contents calibration
This procedure allows calibration of the device measuring system (reactor, cooler, heater) for accurate
measurement of the absolute value of the alcohol content.
Important:
To perform this procedure you need an water-alcohol solution with a previously known alcohol
content. The water-alcohol solution used for calibration must have a nominal value in the range of
9.00% to 13.00% and a deviation from the nominal value no more than +/- 0.02%.
The minimum amount of water-alcohol solution required to perform a calibration procedure is 600
mL.
This procedure must be performed very careful, as it determines the absolute accuracy of the
measured alcohol content of all subsequent measurements until the next calibration.
Note: In case the pressure sensor is disabled, the procedure for calibration of the alcohol content includes
(starts with) several measurements of the boiling temperature of distilled water.
The minimum required amount of distilled water is 400 mL.
To select the alcohol content calibration mode from the "Calibration" menu (see section 5.4.5), select the
"Alcohol content calibration" option using <Down arrow> / <Up arrow> and then confirm with the <OK>
button.
The following warning message will appear on the display:
