• 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 oce 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.

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
congure your handheld rst (go to ‘2. Congurations’).
4.1. ACR System management
You can dene 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.
•Create new ACR system
Main Menu

11
4. Determine the Superheat, Subcool and
evaporator exit air temperature target.
7. Assign the sensors, choose ‘Place sensors’
(If you haven’t physically put the sensors on the
system, put the sensors on the system).
9. Select a spot on the system. You will get
a list of available sensors eligible for this
position and whose signal is received.
10. You can also press the locate button
on the sensor. The sensor code will start
blinking on the handheld.
11. When all sensors are assigned (*), select
‘OK’ in the right bottom corner. This will give
you the ‘ACR Sytem’ again.
8. You have the possibility to assign pressure,
temperature, vacuum sensors and amperage
sensors. Or you can choose to give them a
name in generic sensors:
12. Select ‘Save System’ when all data is
correct. The system is saved. You get the
‘All Values’ menu with all the measured and
calculated values (You will get a warning if
you didn’t select or create a system.).
(*) (Sensors can only be assigned on a dened
ACR system.)
Warning ‘All Values’

12
If you have created and saved ACR systems, you can choose a system in your list of clients and
their systems. By choosing this, the placement of the sensors of your current system will be
lost.
All the necessary data is available, you don’t have to re-enter the data at each service:
4. Select the customer whose system you are
servicing.
5. Select the ACR system.
10. Observe the measured values in
‘All Values’.
• Choose existing ACR system
3. Select ‘Choose Existing ACR System’.
6. Change the data if necessary.
7. Check the targets.
8. ’Place sensors’ & ‘OK’.
9. ‘Save system’.
11. Consult Diagnosis. (see 4.2.)
12. Use the measured values in a
Measurement Report. (see 4.3.)
1. Go to ‘Main Menu’.
2. Select ‘ACR System’.
Main Menu

13
If you have created and saved ACR systems,
you can modify the data. The main idea is to
change the placement of the sensors while
servicing.
1. Repeat ‘Choose existing ACR system’ till
step 3 if you have chosen the system or till
step 5 if you still need to choose the system.
4. Change the placement of the sensors. By
selecting a placed sensor you can undo it’s
placement and assign it on a dierent spot.
(system can be saved without sensors being
placed).
5. Conrm with ‘OK’.
6. ‘Save System’.
• Edit current ACR system
Saved systems can be removed (deleted):
1. Select ‘Remove Existing ACR System’.
2. Select a client.
3. Select the system you want to remove.
4. Conrm removal of system.
• Remove existing ACR system
2. Change refrigerant if needed.
3. Change targets.
7. Continue your working procedure in ‘All
System Values’ and obeserve the measured
values while walking around.
Entire clients can only be removed on PC.

14
4.2. Performing measurement and diagnosis
• Measurements
Measurements, measured and calculated (in ‘All System Values’), can be performed from
the moment sensors are placed physically onto the ACR system. The sensors also need to be
‘placed’ on an existing system in Metreco. (‘ACR System’ - ‘Place Sensors’).
By combining dierent sensors, e.g. pressure and temperature, extra values can be
calculated.
This is the list of the dierent values that can be measured or calculated:
: Low pressure
: Saturated Evaporation temperature (refrigerant)
: Superheat
: High pressure
: Saturated Condensation temperature (refrigerant)
: Subcool
: Oil pressure
: Temperature low pressure side
: Temperature high pressure side
: Air temperature at condensor inlet
: Air temperature at condensor outlet
: Temperature Delta of air over condensor
: Air temperature at evaporator inlet
: Air temperature at evaporator outlet
: Temperature Delta of air over evaporator
: Pressure at condensor outlet
: Pressure Delta over condensor
: Pressure at lter outlet
: Pressure Delta over lter
: Pressure at evaporator inlet
: Pressure Delta over evaporator
: Vacuum pressure

• Diagnosis
In this chapter you will learn how to use the diagnosis tool. Metreco can suggest possible
causes (*) for o-target measurements.
First of all you will need to dene targets for the following measurements:
Superheat Subcool Evaporator exit
air temperature
Check the dynamic history of every measured and calculated value and its divergence to the
dened target on your Metreco Handheld. Per sensor, the last 10 measured values are shown.
(*) This is a non-limited list that serves only as an indication. The engineer has to make his own diagnosis and has
to be in possession of the certicates mandatory by law and the knowledge to service ACR systems.
1. Select a value in ‘All Values’. 2. You will get a history of this value. If the
value has a dened target you can consult a
diagnosis (*) with possible causes.
3. By selecting ‘Plot history’ the data will be
plotted on the screen.
History Diagnosis (*)History
with target
1. Choose an ACR system (see 4.1.).
2. Dene the 3 targets and select ‘Done’.
3. From now on you will get a warning if a
value is o-target.
4. Select ‘OK’ to continue or ‘Value’ to check
the o-target value.

16
4.3. Logging & Reports
- Logging data creates a logle (.csv) and a Measurement Report
- Pressure Decay Test creates a logle (.csv) and a Pressure Decay Test Report (long & short)
- Vacuum Decay Test creates a logle (.csv) and a Vaccum Decay Test Report (long & short)
• Logging
When you apply ‘logging’, the measured values will be memorised with a standard interval of
5 seconds. This data can be used in Measurement Reports. You’re getting a list of saved data
(time & value) that you can retrieve from the Metreco on your PC via USB. This can then be
used for technical or commercial purposes (see ‘4.5. Customer & Systems follow-up’).
The standard interval between 2 loggings is 5 seconds. You can modify this interval in
the conguration menu (see ‘3. Conguration’).
1. Select ‘Logging’ to start the logging process. The logging icon ‘L’ will start blinking.
2. Select ‘Logging’ again to end the process. The logging icon ‘L’ will stop blinking.
When you end the logging process, a new Measurement report with the last logged measured
values is automatically created (see next point -> Measurement Report), all the logged values
are saved in a ‘LOG’ le (.csv).
There are over 1.000.000.000 data points...
Logging

17
• Measurement Report
- A Measurement Report is a survey of the performed measurements that you can use for tech-
nical and commercial purposes.
- A Measurement Report gives you the last logged measured values before ending the logging.
The report is saved automatically when ending the logging and can be recalled on Metreco and
downloaded on PC for later use in internal reports or reports to your customer.
5. The Measurement Report contains a
summary of:
- customer data
- system data
- placed sensors
