About this document

i Please read this documentation through carefully and familiarize yourself with

the product before putting it to use. Keep this document to hand so that you
can refer to it when necessary. Hand this documentation on to any
subsequent users of the product.

i Pay particular attention to information emphasized by the following symbols:

· With the signal word

Warning!

:
Warns against hazards which could result in serious physical injury
if the precautionary measures indicated are not taken.

· With the signal word

Caution!

:
Warns against hazards which could result in minor physical injury
or damage to equipment if the precautionary measures indicated
are not taken.

· Important information!

Avoiding personal injury / damage to equipment

i Do not make measurements with the measuring instrument and its sensors

on or near live components unless the instrument is expressly approved for
current/voltage measurements!

i Never store the measuring instrument together with solvents and do not use

any desiccants.

i Only operate the measuring instrument properly, for its intended purpose

and within the parameters specified in the technical data. Do not use force.

i Only carry out the maintenance and repair work that is described in the

documentation. Follow the prescribed steps when doing so. Use only OEM
spare parts from Testo.

Safety and the environment 5

Warning!

Danger of injury exists if highly pressurized hot, cold and/or toxic
refrigerants escape. For this reason, always wear protective glasses
and protective gloves when carrying out measurements and other
work on the refrigeration system.

If the measuring instrument falls down or is exposed to any other
comparable mechanical strain, the end connections of the refrigerant
hoses can break off. The valve knobs can also be damaged, which
can lead to further damage in the interior of the instrument, which is
not visible externally. For this reason, replace the refrigerant hoses
after any fall or comparable mechanical strain with new, undamaged
refrigerant hoses. For your own safety, send the instrument to Testo
customer service for technical testing.

Protecting the environment

i Refrigerant gases can harm the environment. Please note the applicable

environmental regulations.

i Take faulty rechargeable batteries / spent batteries to the collection points

provided for them.

i Send the product back to Testo at the end of its useful life. We will ensure

that it is disposed of in an environmentally friendly manner.

Functions and use

testo 556 and testo 560 are refrigeration system analyzers for maintenance and
service work on (large) refrigerating systems and heat pumps. The testo 560
furthermore offers a vacuum function for commissioning work. The instruments
may only be used by qualified authorized personnel.

With their functions, the testo 556 and the testo 560 replace mechanical
manifolds, thermometers and pressure/temperature tables. Pressures and
temperatures can be loaded, adjusted, tested and monitored.

The range of functions can be expanded through comprehensive, separately
available accessories, e. g.: Various temperature probes (also radio probes),
clamp-on probe*, refrigerant scale*, oil pressure probe*, PC software.

testo 556 and testo 560 are compatible with most non-corrosive refrigerants,
water and glycol. testo 556-1 and testo 560-1 are not compatible with
refrigerants which contain ammonia.

The product must

not

be used in areas at risk of explosion!

* Option not available as standard. Please ask your local Testo subsidiary.

(fast evaporation of liquid), poisoning or asphyxiation (displacement
of air oxygen) exists for the user.

i Operate the instrument only with protective equipment (protective

goggles, protective gloves). For ammonia refrigerants, additionally
wear breathing equipment.

i Observe the descriptions of danger and information on protective

equipment in the safety data sheet of the respective refrigerant
use.

First steps10

First steps

²

Inserting bbatteries / rechargeable bbatteries/radio mmodule:

Radio probes may only be used in countries in which they are permitted
(see radio probe instructions).

A radio module (accessory part) is required for the use of radio probes.
The instrument can establish a connection with a maximum of two radio
probes.

Each radio probe has a probe ID (RF ID). This consists of the last 3
numbers of the serial no. and the position of the slide switch in the radio
probe (H or L).

1 Fold out the suspension device and open the battery compartment (clip

lock).

2 Insert buffer battery (included in delivery, 1x 3V lithium CR2032) in the

battery compartment. Observe the polarity (positive pole up)!

3 Push radio module (accessory) into the module slot underneath the buffer

battery until the module engages (contact strip facing up).

4 Insert batteries (included in delivery) or rechargeable batteries (4x 1.5V,

type AA / mignon / LR6) into the battery compartment. Observe the
polarity!

5 Close the battery compartment.

When not in use for long period: Read out memory and remove batteries
(not the buffer battery).

When operating the instrument with the mains unit, insert batteries in
order to avoid switching off the instrument in case of a power interruption.

Switching tthe iinstrument ooff:

i Press .

²

Operate vvalve ppositioner:

The function of the valve positioners is independent of the selected setting
position. For easier operation, it is recommended that you unlock the
required valve positioners. For transport, the valve positioners should be
retracted.

i Unlock valve positioners: Press unlock button.

i Retract valve positioner: Press valve positioner into the housing. The

refrigeration system analyzer acts like a conventional four-way manifold
with regard to the refrigerant path. The passages are opened by opening
the valves. The adjacent pressure is measured with valves closed as well
as with them open.

i Open valve: Turn the valve positioner anticlockwise

i Close valve: Turn the valve positioner clockwise.

Warning!

Tighten valve positioner only hand-tight. Do not use tools to tighten
the valve positioner, as the thread may be damaged thereby!

Preparing for measurement

²

Connecting tthe ttemperature pprobe / accessories:

Probes /accessories must be connected before the measuring instrument
is switched on so that they are recognized by the measuring instrument.

If probes / accessories are connected afterwards, a probe search must be
carried out: Set > Probes > Probe search. Alternative (only available in
standard measurement view): Set must be held down for 2s.

If radio probes are to be used, these must first be selected (Set > Probes >

Radio probe select) and assigned (Set > Probes > Probe mapping).

1 Open socket cover on the left / right side of the instrument.

2 Insert the connector of the accessory into the probe socket:

Accessories Measurement task (measurement channel) Socket

Temperature probe (blue) Overheating (toh) or temperature difference (t1) left
Temperature probe (red) Undercooling (tcu) or temperature difference (t2) right
Clamp-on probe* Compressor performance (l) right

Using the product14

²

Zeroing tthe ppressure ssensors:

Carry out a zeroing of the pressure sensors before every measurement.

The measurement values can be falsified by a change in the position of
the measuring instrument. After zeroing, the position of the measuring
instrument must not be changed. Carry out zeroing before every
measurement in order to compensate faulty positioning or long-term zero­point drift. Zeroing is only possible in a range of ±1bar(rel)/±14.5psi (rel)
or 0...2bar(abs) / ±29psi (abs).

1 Press Set function key.

- p=0 is displayed.

2 Press OK function key to carry out zeroing.

²

Connect rrefrigerant hhoses:

 The valve positioners are closed.

1 Connect refrigerant hoses for low-pressure side (blue) and high-pressure

side (red) to the measuring instrument.

2 Connect refrigerant hoses to the system.

Warning!

If the measuring instrument falls down or is exposed to any other
comparable mechanical strain, the end connections of the refrigerant
hoses can break off. The valve knobs can also be damaged, which
can lead to further damage in the interior of the instrument, which is
not visible externally. For this reason, replace the refrigerant hoses
after any fall or comparable mechanical strain with new, undamaged
refrigerant hoses. For your own safety, send the instrument to Testo
customer service for technical testing.
