non-condensable gases that can
cause problems in a system.
There are many ways to connect to
the system, Fieldpiece recommends
using a SCRT and the shortest vacuum
rated hoses possible. Fewer connec-
tions reduce the potential for leaks.

How to Activate the Alarms
1. Press ALARM to activate low alarm.
2. Press ALARM again to deactivate low alarm and
activate high alarm.
3. Press ALARM again to deactivate high alarm and
return to real time mode.
How to Set the Alarms
The default low (500 microns) and
high (1000 microns) alarm values can
easily be set to whatever you want.
1. Hold ALARM for 1 second to enter Alarm Set Mode.
The first digit of LO alarm will blink.
2. Use ARROWS to change the blinking number. Press
ENTER to lock in a digit and move to the next digit.
Repeat for all LO alarm digits.
3. When LO alarm is complete, the first digit of HI alarm
will blink. Use ARROWS to change the blinking
number. Press ENTER to lock in a digit and move to
the next digit. Repeat for all HI alarm digits.
4. When all digits of HI alarm are locked in you will
automatically exit Alarm Set Mode and your
customized alarm values will be saved.
Note: Anytime while in Alarm Set Mode, you can press
ALARM to toggle between alarm HI set and alarm
LO set. Hold ALARM to exit Alarm Set Mode and
save at any time.
Note: "Err" will show if you try to set the HI alarm
lower than the LO alarm, or the LO alarm higher
than the HI alarm.

Vacuum Tips
Follow all manufacturer's evacu-
ation procedures over those in this
manual in regards to specifications on
how to evacuate systems. To achieve
a deep vacuum efficiently Fieldpiece
recommends the following practices.
1. Remove Schrader cores and core depressors from
the service ports using a valve core removal tool
(purchased separately).
2. Use the shortest vacuum rated hoses with the
largest diameter available.
3. Inspect rubber seals at both ends of your hoses for
damage that may result in leakage.
4. Avoid using hoses with low loss fittings when
evacuating a system.
5. Avoid over-tightening the female flare fitting of
the SVG3. Over-tightening may cause the rubber
gasket to wear more quickly and create leaks. It is
not necessary to over tighten SVG3 to the extreme
to create a good seal.
