2.2. Ensure safety
> Only operate the product properly, for its intended purpose and
within the parameters specified in the technical data. Do not
use any force.
> Do not operate the instrument if there are signs of damage at
the housing, mains unit or feed lines.
> Do not perform contact measurements on non-insulated, live
parts.
> Do not store the product together with solvents. Do not use any
desiccants.
> Carry out only the maintenance and repair work on this
instrument that is described in the documentation. Follow the
prescribed steps exactly. Use only original spare parts
from Testo.
> Any further or additional work must only be carried out by
authorised personnel. Testo will otherwise refuse to accept
responsibility for the proper functioning of the measuring
instrument after repair and for the validity of certifications.
> Only use the device in closed, dry rooms and protect it from rain
and moisture.
> Temperatures given on probes/sensors relate only to the
measuring range of the sensors. Do not expose handles and
feed lines to any temperatures in excess of 70 °C unless they
are expressly permitted for higher temperatures.
> The gas feeding unit should only be emptied in an open
environment.
> Do not operate the instrument if there are signs of damage at
the housing, mains unit or feed lines.
> Dangers may also arise from the systems being measured or
the measuring environment: Note the safety regulations valid in
your area when performing the measurements.

For products with Bluetooth®(optional)
Changes or modifications that have been made without the explicit
consent of the responsible approval authority, may cause the
retraction of the type approval.
Data transfer may be disturbed by equipment that uses the same
ISM-band, e.g. WLAN, microwave ovens, ZigBee.
The use of radio communication links is not permitted, among
others, in aeroplanes and hospitals. For this reason the following
points must be ensured before entering:
> Switch off the device:
> Isolate the device from any external power sources (mains
cable, external rechargeable batteries, ...).
2.3. Protecting the environment
> Dispose of faulty rechargeable batteries/spent batteries in
accordance with the valid legal specifications.
> At the end of its useful life, send the product to the separate
collection for electric and electronic devices (observe local
regulations) or return the product to Testo for disposal.

3.1. Use
testo 324
The testo 324 is a leakage measuring instrument for the
professional performance of the following measuring tasks:
• Pretest and main test on gas pipes
• Determining the usability of gas pipes
• Measuring low pressure against atmospheric pressure
• Pressure test on waste water pipes
• Pressure tests on liquid gas pipes
• Controller test
• Temperature measur ement
WARNING
Escaping gas can produce an explosive mixture of gases!
Potential risk of explosion!
>The testo 324 leakage measuring instrument may only be used
by authorised personnel who have been trained in the
maintenance and inspection of gas systems.
> Observe local accident prevention and test regulations.
Testo guarantees the functionality of its products when
used in accordance with their intended purpose. This
guarantee does not apply to features of Testo products in
combination with unauthorised third-party products.
Competitor products are not authorised by Testo.
As is common practice, Testo generally excludes support,
warranty or guarantee claims relating to functionality that
has not been guaranteed by Testo as part of the product
offered. Claims shall also be excluded in the event of
improper use or handling of the products, e.g. in
combination with unauthorised third-party products.

The use of the wireless module is subject to the regulations
and stipulations of the respective country of use, and the
module may only be used in countries for which a country

prerequisites for use, and acknowledges that the re-sale,
export, import etc. in particular in countries without wireless
permits, is his responsibility.
Feeding unit
When used in conjunction with the testo 324 leakage measuring
instrument, the feeding unit (gas bladder) enables leakage
measurement to be carried out independently of the gas supply.
3.1. Physical principles
3.1.1. Physical influence of temperature on the pressure to
be measured
Temperature fluctuations and positional changes have an effect on
the measuring accuracy of pressure measurements. The following
should therefore be observed:
✓The entire measurement system must be adapted to the
ambient temperature and to the temperature of the line system
to be tested.
✓The temperature of the measurement system and the line
system must remain stable during measurement.
Example of temperature influence:
with a test pressure of 100 hPa and an air pressure of 1000 hPa,
the ambient temperature changes from +22 °C to +23 °C. The air in
the test system expands and the test pressure increases by
3.73 hPa. The temperature influence on the pressure change is
unaffected by the test volume.
3.1.2. The standardised measurement result of the testo
324 relating to temperature influences
The testo 324 leak rate measuring instrument certified to
DVGW G 5952 enables measuring values to be reproduced.
Comparable results based on the standardised reference operating
pressure of 23 mbar are always achieved. The volume measured
during the test is based on a reference temperature of 20 °C and
the current air pressure.
A change in the ambient temperature therefore has no influence on
the measuring values!
The ambient temperature and the relevant test gas or medium for
each test section must nevertheless show a constant temperature

3 Specifications
12
within the range of 15 °C to 25 °C with a maximum deviation of ±
2 °C. Only then can a measurement be carried out. During the
stability time at the start of each measurement, this check is carried
out automatically and a warning is issued if the temperature and
therefore the pressure fluctuates too greatly.
