Note: In case the connectors will not be put in the right way they will be damaged. This type
of damage is not covered by manufacturer's warranty.
The device can be charged only with the supplied adaptor. Average charging time is about 8 hours
and the voltage of a charged accumulator is nearly 19V. „Recharge battery" is displayed under
16.5V and „Low voltage" under 15.5V The charging time can be shortened if needed but the
running period and the accumulator life-time will be shortened too. Once the charging of the device
is over, unplug the adaptor and the connector from the device. Then screw the cap of the connector
(13) for protection and press the power button (12) to turn off.
Notice: If the power button (12) is switched off during charging than the accumulator isn't
charging.

ONTENT MEASUREMENT

Follow the paragraphs 5.1.1. and 5.1.2 and further:
1) Press the power button (12) to turn on and then press the key ON to switch on the
microcomputer. The text „1-CUBE" with the program version appears on the display for a moment.
Then the following text appears:
„ENT.meas." | „+ view."
2) Press the key ENTER. At the beginning of the measurement sequence, the pressure is measured
and displayed, until the pressure goes under the threshold value. This is achieved by opening
briefly the outlet valve (2). When the pressure is low enough, you will hear the buzzer of the GMD
and the display shows "close v.", which indicates that you have to close immediately the valve (2).
Now you can start releasing the CO
from the beer with the pump on the top of the GMD (look
2
pic.2). Push out the button (9) of the secured position (10b) and pull it out into the upper position
(11). Hold it for a while in this position to equalize the pressure. Then press down the button (9) to
the very down unsecured position (10 a). After this handling dissolved CO
is fluttered and the
2
pressure increases in the chamber (6). Repeat this action one more time. Use it two times, not less,
not more, then be sure to secure the piston in the down position. Press the Enter key and
„measure" is displayed. The program waits a while for equilibrium, then the measured value of
pressure (e.g. 140kPa), followed by the measured value of temperature (e.g. 5.0 °C) appear on the
display.
Finally, the computed value of CO
content is shown e.g. 0.51 %bw | 5.1 g/l

By displaying CO
content the measurement of sample is over and the CO
value is saved in the
2
2
GMD(K) memory.
Press the key ENTER to finish the measurement, the text:
„ENT.meas." | „+ view."
The device is ready for next measurement. When the new sample has been taken, you just need to
repeat this procedure to measure it. If it has been automatically shut off, switch it on as described
above. Press the power button (12) to turn off once the measurement is finished.
