Do not open in order to prevent electrocution.•
Repair & maintenance should be done by qualied personel.•
Warranty is void if you have attempted to open the product or dismantle it.•
Don’t wet or short-circuit the battery charging contacts.•
For charging the batteries, only use the dedicated spaces in the charging station.•
Use only included AC adaptor for connecting the charging station to the mains.•
Use only included cigarette lighter plug for connecting the charging station to your 12V•
source (car etc.).
Use only a USB 2.0 compliant cable (included) with the correct plugs to connect the hand-•
held to the PC.
If irradiance occurs of an electromagnetic eld of 30 V/m at the frequencies of 325-340 •
MHz and 865-880 MHz, the wireless communication can get disturbed.
Working temperature: -30..+70 °C (for optimal battery capacity: -20..+60°C).•

Metreco Concept
Thank you for choosing the Metreco Concept. This new way of working brings you
on the edge of the most recent technological possibilities in wireless developments
and gives you a huge competitive advantage.
SMART MOBILE MEASURING
Dynamic measuring with METRECO, Smart Mobile Measuring, instead of static •
measuring with traditional manifold with hoses and temperature probes.
Up to 10 sensors transmit their measurements simultaneously to the Handheld: •
no hoses - no lines.
The user positions himself where he wants/walks around and can read out the•
measurements in real time.
Intuitive/natural easy-to-use interface is operated with a capacitive touch-•
screen.
Dene your measurement/value targets - get a warning when they are o.•
Measurement - Diagnosis - Suggestions / Solutions.•
Database of serviced ACR systems available on Handheld & PC.•
Measurement reports on Handheld & PC.•
Intervention reports on Handheld & PC.•
Charge your handheld and sensor batteries in the specially designed case -•
docking station.
Extra hoses and connectors for handling refrigerant.•

• Scenario:
Engineer Jason services a system of a new client who claims that it ‘doesn’t cool’ any longer.
He places the sensors on the system: low pressure, high pressure and the two temperature
sensors. Jason has instantly, while walking around, access to the measurements in the ‘All
Sensors’ menu.
He creates a new client and system through the touchscreen of the Metreco. He chooses a
refrigerant and the targets for subcool, superheating and evaporator exit air temperature. He
is now looking at the ‘All Measurements’ level and has an instant idea of the measured and
calculated values. If one of the targets is o, he gets a warning with a diagnosis and a possible
cause.
The measured values can be logged, this creates automatically a Measurement report. Jason
also makes an Intervention report where he can keep track of the interventions he has done:
leak detection, lter-dryer, refrigerant adjustment, oil test, pressure test, vacuum test, etc.
Back at the oce Jason connects his Metreco handheld to his PC and makes a report for
internal use and a customer report which is sent by e-mail.

Batteries
Batteries have to be charged during
12hours before rst use!
- The case acts as the docking station for charg-
ing the batteries.
- Charging batteries: put the parts you want to
charge back in the case. Connect the charging-
cable to the 12V power supply in your car or the
230V(110V) AC.

When your sensor has endured an overpressure of more than 2 times the max. pressure, you have
to recalibrate your sensor. (see 5. Service & Support, Calibration and Updates)

2. Conguration
This is the list of parameters you can adapt:
- Units
- Language
- Log interval
- Date & Time
- Screen intensity
- Target Margins
- Update rmware (see 5.3.)
Units Language
Log interval
(go to ‘4.3. Logging’)
Date andTime
3. Change the congurations as desired.
2. Select ‘Congurations’.
Target margins
Screen intensity
1. Go to ’Main Menu’.
Modifying the target margins makes the Metreco more or less tolerant to target value variations
= quicker or slower reaction of the warning pop-up.

3. Measuring
In this part you learn how to quickly measure a pressure, temperature or vacuum:
1. Turn the device ON, slide to the right on the shortcut buttons (during min 1 s).
3. Place the sensors (temperature, pressure, vacuum) on the system and turn them on by
pressing at least for 2 seconds on the button.
4. Observe the measured values.
2. You will see the ‘All Sensors’ screen.
In chapter ‘4. ACR’ the following applications are treated:
- Creating a new ACR system
- Choosing an existing ACR system
- Diagnosis
- Logging
- Measurement report
- Intervention report
- Pressure Decay Test
- Vacuum Decay Test
- Follow-up on Metreco & PC
- Using the hoses & connectors
- Sensor calibration & rmware updates

4. ACR
In order to correctly apply the treated subjects of this chapter, we strongly advise you to
congure your handheld rst (go to ‘2. Congurations’).
4.1. ACR System management
You can dene and save ACR Systems on your Metreco.
1. Go to ‘Main Menu’.
2. Choose ‘ACR System’.
This menu gives you the possibility to:
- create a new ACR system
- choose an existing ACR system
- edit current ACR system
- remove an existing ACR system
1. Choose ‘New ACR System’ and select
‘Client’. Create a new one if needed or select
an existing one.
2. Choose ‘Name’ and complete the name
you want to give to the system
(a client can have many systems).
3. Select the refrigerant of the system.
-> This is an intelligent list. It will change the
order of your refrigerants according to the
frequency of selection of the refrigerants.
Most selected refrigerants will go on top.
