WARNING: for the power
supply of any active probes, it is possible
to use the 12 Vdc available on clamp
+Vdc, the maximum current supplied is
100 mA protected against short circuits.
To power the probes 0...5V use +5 Vref
(30 mA max). Like the pCO1 and pCO2

the 0/1 Vdc signal must be intended
as limited to the restricted range 0-1 V
and is therefore not always compatible
with the standard 10 mV/°C signal
of the Carel probes ( for negative
temperatures and those over 100 °C a
probe alarm can be generated)- For
