Summary
This product is the integration of functions of pressure measurement and
temperature measurement. It is mainly used for leakage detection,
refrigerant charging, troubleshooting and maintenance of the refrigeration
system.
Cautions
To ensure the proper use of this product, please read the operation
instructions carefully:
1. Never disassemble or refit this product personally without authorization.
2. If the hose is damaged, please change it in a timely manner.
3. Do not drop or impact the instrument to avoid damage.
4. The measuring instrument can only be used by qualified and approved
personnel.
5. If this product lies idle for long, please take out the battery to avoid battery
leakage and corrosion.
6. Refrigerant gas will do hazard to the environment, so it is required to
ensure that it will comply with the local environmental regulations when
using it.
7. If there is any failure in the instrument, stop using it and contact the
supplier or manufacturer in time.
8. Do not discard the waste batteries at will, but send them to the specified
collection points for waste batteries.
9. Please evaluate whether the measuring object or environment is safe, and
note the safety standards in your measuring areas.
10. The instrument is suitable for the measurement of most non corrosive
refrigerants, water and alcohol media. The instrument may not be used in
explosion-proof areas.

1. Setting pressure units
From the pressure unit setting interface, press the “▲ ” button or “ ▼” button
to switch the pressure units. There are four pressure units in all: kpa, Mpa,
psi and bar
2. Setting temperature units
From the temperature unit setting interface, press the “▲ ” button or “ ▼” bu
tton to switch temperature units. There are 2 temperature units in all: ℃ and ℉.

3. Setting relative/absolute pressure
From the relative/absolute pressure setting interface, press the “▲ ” button
or “▼ ” button to select the relative pressure measurement mode or absolute
pressure measurement mode.
Absolute pressure: pressure value by adding air pressure.
Relative pressure: pressure value minus air pressure.
If the relative pressure measurement mode is chosen: according to the
selected pressure unit, prel or psig is displayed at the left upper cornerof the
screen.
If the absolute measurement is chosen: according to the selected pressure
measurement unit, pabs or psia is displayed at the left upper corner of the
screen.
4. Air pressure setting interface
There is difference in air pressure in different areas. The user will make
adjustments to air pressure at the place where he or she is currently located.
From the air pressure setting interface, press the “▲ ” button or “▼ ” button
to adjust the air pressure value.
5. Setting the refrigerating/heating modes
From the refrigerating/heating mode setting interface, press the “▲” button or
“ ▼” button to select one of the modes. There are three modes in all: hot
pump mode, refrigerating mode, and automatic mode.
6. Setting automatic power off functions
From the automatic power off function setting interface, press “▲ ” button or
“▼ ” button, select “on” to turn on the automatic power off function, and
select “off” to turn off the automatic power off function. When the automatic
power off function is turned on: if you do not press the button within 20
minutes, it will be automatically shut down.

Disposal
For the disposal of batteries in the EU, the 2006/66/EC directive of the
European Parliament applies. Due to the contained pollutants, batteries must not
be disposed of as household waste. They must be given to collection points
designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We
either re-use them or give them to a recycling company which disposes of the
devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in
accordance with your local waste regulations.
If you have any questions, please contact PCE Instruments.
