Safety and disposal
· In principle, contact with escaping battery components may present a risk to
health and to the environment. Adequate body and respiratory protection is
therefore required when in contact with batteries that exhibit abnormalities
(escaping contents, deformations, discolourations, dents or the like).
· Batteries must be disposed of in accordance with the local and
countryspecific regulations. In order to prevent short circuits and the
associated heating, lithium batteries must never be stored unprotected in
bulk. Appropriate measures against short circuits are, for instance, inserting
the batteries into the original packaging or a plastic bag, masking the poles
or embedding them in dry sand.
· Lithium batteries must be transported and shipped in accordance with the
local and country-specific regulations.
· If there is any contact with the skin or eyes, the areas must be rinsed with
water for at least 15 minutes. If there is any contact with the eyes, a doctor
must be contacted in addition to the rinsing.
· If burns are caused, these must be treated appropriately. You are also
strongly advised to contact a doctor.
· Airways: leave the room immediately when smoke development or gas release is
acute. Consult a doctor when amounts are larger and airways are irritated.
· Swallowing: rinse out mouth and surrounding area with water. Get medical
assistance immediately.

2 Safety and disposal
VORSICHT Refrigerant gases can harm the environment. – Please note the
applicable environmental regulations.
Explosion hazard when using A2, A2L and A3 refrigerants During maintenance and
repair work on refrigeration systems with flammable refrigerants (e.g.
category A2L, A2 and A3 of ISO 817), a hazardous and explosive atmosphere must
always be expected in the immediate vicinity of the system. The testo 570s may
only be operated outside of designated, recognizable or assumed explosion
hazard zones (acc. to IEC 60079-10-1).
The following occupational safety measures must be observed to avoid a
hazardous explosive atmosphere (see also: TRBS 1112, TRBS 2152 and VDMA
24020-3):
· Wear protective goggles and gloves.
· Before applying pressure to the measuring instrument: Always attach the
measuring instrument to the suspension device to prevent it from falling down
(risk of breakage).
· Before each measurement, check that the refrigerant hoses are intact and
correctly connected. Do not use any tools to connect the hoses, only hand-
tighten the hoses (max. torque 5.0 Nm / 3.7 ftlb).
· Adhere to the permissible measuring range (-1…60 bar/-14.7…870 psi). Pay
particular attention to this for systems with refrigerant R744, as these are
often operated at higher pressures!
· Open and close valves on the unit in the correct sequence to prevent any
leakage of refrigerant from the system throughout the commissioning,
maintenance and repair period.

Using the product
Automatic mode
The manifold automatically detects the pressure difference between the
lowpressure and high-pressure sides. If the measured pressure on the low
pressure side is 1 bar higher than on the high pressure side, a dialogue
appears and the display can be changed accordingly. If “yes” is selected, the
low pressure moves from left to right and the high pressure moves from right
to left. This mode is particularly suitable for air conditioning systems that
provide cooling and heating.
Measuring mode
WARNING Risk of injury caused by refrigerant that is under high pressure, hot,
cold, or toxic! > Wear protective goggles and safety gloves. > Before applying
pressure to the measuring instrument: Always fasten the
measuring instrument on the suspension hook to prevent it from falling (danger
of breakage). > Before each measurement, check the refrigerant hoses are
intact and connected properly. Do not use any tools to connect the hoses; only
tighten hoses hand-tight (max. torque 5.0 Nm/3.7 ft*lb). > Comply with the
permissible measuring range (-1 to 60 bar/-14.7 to 870 psi). Pay particular
attention to this in systems with R744 refrigerant, since these are frequently
operated at higher pressures!
Refrigeration
The Refrigeration application is used to determine the following system
measuring values: · High pressure · Low pressure · Refrigerant evaporating
temperature · Refrigerant condensation temperature · Temperature of suction

The temperature compensated leakage test can be used to check the leak
tightness of systems. For this purpose both the system pressure and the
ambient temperature are measured over a defined period of time.
To this end, a temperature probe may be connected to measure the ambient
temperature (recommendation: Deactivate the surface compensation factor and
use an NTC air probe or Bluetooth® temperature Smart Probes) or Smart Probe
for air temperature measurement. This provides information about the
temperaturecompensated differential pressure and the temperature at the
beginning/end of the test. Due to the temperature compensation, the actual
pressure drop is displayed as delta P. If no temperature probe is

compensation.
Surface temperature probes (e.g. testo 115i) can also be used for the
temperature-compensated leakage test, but must not be used for measuring
surface temperature. They must be positioned as far as possible to measure the
air temperature.
