1. Press and hold the
SET
key until the display shows a unit of measurement such as kPa,

InHg
for inches
of mercury.

screen with a low number on it for the current/live reading.
4. Press the
SET

production.
System vacuum switch settings – P_1 = 18; P_2 = 15
Secondary vacuum switch settings – P_1 = 15; P_2 = 12
By setting these switches up in this manner the Vacuum switch will provide an output when we get
to

InHg and it will not loose its signal unless we drop below
15.0
InHg.
