WARNING
• Wear safety goggles when working
with refrigerants. Refrigerants can
cause eye injury.
• Disconnect hoses using extreme
caution. Pressurized refrigerant may
be present in hoses. Point hoses away
from you and anyone nearby.
Instructions
This product is a convertible pressure gauge that
measures pressure and then displays results and
temperature on the LCD.
Setup
1. Press and hold the ON / TARE button for
two seconds. All positions on the gauge are
illuminated for two seconds.

2. The gauge must be calibrated before use. With
the gauge turned ON and no pressure applied,
press the ON / TARE button two times. The
gauge displays 0.0, and is now calibrated and
ready for use.

4. Select unit of temperature by using the tip
of a pencil to press the units button on the
back of the gauge for two seconds until the
temperature indicator on the LCD begins to
ash. The gauge is now in temperature unit
selection mode.
Press the units button again to cycle between
between Celsius or Fahrenheit. Once the
desired selection has been made, press and
hold the units button again for two seconds
until the indicator on the LCD begins to ash.
This exits temperature unit selection mode.
Pressing the units button now will adjust the
pressure units displayed on the LCD.
Installing the Gauge
1.
Press and hold the ON / TARE button for two
seconds to turn the gauge OFF before installation.
2. Install the gauge by using a wrench on the
gauge’s brass tting. CAUTION: Do NOT
tighten the gauge by hand; this will damage
the gauge and void warranty.
3. Press the ON / TARE button. All positions on
the gauge illuminate for two seconds; then
the display changes to the last stored features
(units of pressure / temperature and type of
refrigerant) along with the current pressure
and temperature reading.

Note: If 0.0 does not appear on the display, the
calibration procedure was not successful. Turn OFF
the gauge by pressing and holding the ON / TARE
button for two seconds. Press the ON / TARE button
again to turn the gauge ON and recalibrate (repeat
Step 2). It may be necessary to repeat this procedure
until the gauge is calibrated.
3. Select unit of measure
by rst removing
the rubber boot from
around the gauge. Use
the tip of a pencil to
press the units button
while watching the
LCD display. Pause when
the correct unit is displayed
on the gauge face.

4. Select type of refrigerant by pressing the R
button to scroll through the choices. Pause
when the correct refrigerant is displayed on
the gauge face.
To display only pressure, scroll through the
refrigerants until ---- is displayed.
Note: When a refrigerant is chosen, if pressure
is higher or lower than what is dened for that
type of refrigerant, the gauge displays Or in the
temperature eld. “Or” = out of range.
5. When testing is complete, turn OFF the gauge
by pressing and holding the ON / TARE button
for two seconds.
If left ON, the gauge automatically shuts
OFF after 10 minutes of displaying a stable
pressure reading.
