Pressure gauge threshold
This function can be used to define the mainte-
nance interval of the desoldering tool. This is done
by setting the value in mbar at which the electric
pressure gauge issues a warning signal when the
intake system is contaminated (LED of the vacuum
pump switches from green to red). The set value is
dependent on the suction nozzles used.
Adjustable -400 mbar to -800 mbar
factory setting -600 mbar
