2.4.3. Putting into operation
When the supply voltage for the unit is switched on, a short beep is hearable and after a short time
the LEDs of the internal and external user interface shows the specified conditions confirming that
the HYDROCAL unit is working correctly (4).
After successful initialization, you can remount the protection cover and fasten it with the
knurled thumb screw.
The measurement cycles are performed every 20 minutes and are synchronized on the clock
mark; this means the first measurement values are available approx. 2, 22 or 42 min. after the
clock mark.
To check the heating function, touch carefully the back plate after some minutes.
