ALARM 1/2 (USP)
The TEMP menu allows the temperature to be
entered in cases where no measurement is
provided by Pt100/Pt1000. If temperature is
measured automatically, this menu is not
displayed.
The LEVEL menu is used to set the safety margin
with respect to the USP standard: with a level of
50%, the 1.9 μS/cm threshold (50°C) drops to 0.95
μS/cm.
