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.
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
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.
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 fitting. 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.
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 defined for that
type of refrigerant, the gauge displays Or in the
temperature field. “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.
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.
