How to Use
Normal Mode
Recommended
Measure deep vacuums to moni-
tor your system evacuations. Deep
vacuums remove moisture and
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.

1. Connect to system. Techs typically prefer connect-

ing to the Schrader Core Removal Tool (SCRT) or an
unused service port.
2. Hold
for 1 second to power ON the SVG3.
3. The top display shows the vacuum in microns of
mercury.
4. The bottom display shows how fast the measure-
ment is increasing or decreasing (± microns of
mercury per minute).

exposed to atmosphere is critical to
ensure the system is dry and tight.
SVG3 is the right tool to help HVACR
professionals verify they reach proper
vacuum levels. See your vacuum
measurement clearly and easily with
the newly designed easy-view hook
and backlight. SVG3 is built for field
use with its ruggedized rubber case.

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.
