Description of the instrument
3.1
Use
The testo 552 is a digital vacuum gauge for the precise measurement of
extremely small pressures in the vacuum range. This allows you to monitor the
evacuation (usually during commissioning) of refrigeration systems and heat
pumps.
With the testo 552, you can therefore measure the current pressure in a
refrigeration system, and thus gather information about the degree of
dehumidification and the removal of foreign matter (oils, foreign gases, etc.).
A vacuum gauge is always used in conjunction with a vacuum pump (generates
the vacuum). A manifold (analogue or digital) is also often used in order to
obtain controlled access to the refrigeration system.

Operating as a probe on the testo 570
The testo 552 has no save or transmission function of its own.
By connecting the testo 552 to the testo 570, the data is transferred to the
testo 570. From there the data can be saved or managed via the EasyKool
software.
In combination with the testo 570, the testo 552 can be used as a high
precision vacuum probe, if connected to the front of the testo 570
using the connection cable 0554 5520. The firmware version 1.09 or
later must be installed for this.
Before connecting both instruments, the testo 552 must be switched
on and the same pressure unit must be set on both instruments.
The testo 570 will only connect to the testo 552 once the Evacuation
mode has been activated. When used as a probe, the testo 552 cannot
be operated, all keys are deactivated.
In order to be able to use the readings from the testo 552 via the testo
570 in the EasyKool software, you need EasyKool software version 4.0
or later.
