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.

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

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 measurement
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

prerequisites for use, and acknowledges that the re-sale,

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.

5.1. Commissioning
testo 324
The testo 324 has a permanently installed rechargeable battery.
> Charge the rechargeable battery fully before using the
measuring instrument.
> Remove the protective film from the display.
Feeding unit
Flushing is required when starting up the unit for the first time, after
replacing the gas bladder and when changing the medium.
> Fill and empty the feeding unit once, see Options menu, page
38
5.2. Getting to know the product
5.2.1. Mains unit, rechargeable batteries
In case of an extended interruption in the power supply to
the testo 324 (e.g. rechargeable battery pack empty), the
date/time settings will be lost.
5.2.1.1. Charging the battery
The rechargeable battery can only be charged at an ambient
temperature of 5 to +35 °C. If the rechargeable battery pack has
discharged completely, the charging time at room temperature is
approx. 5 - 6 h (charging with mains adapter).
Charging via a mains unit
✓ The testo 324 is off.
1. Connect the mains unit instrument plug to the mains unit
socket.
2. Connect the mains plug of the mains unit to a mains socket.
- The charging process starts. The charge status is shown on the
display.
- Once the rechargeable battery has been charged, the
instrument switches over automatically to trickle charge.
5 First steps
23
5.2.1.2. Rechargeable battery care
> Do not fully exhaust rechargeable batteries.
> For extended periods of disuse, you should discharge and
recharge the batteries every 3 - 4 months. Trickle charging
should not exceed 2 days.
5.2.1.3. Mains operation
In case of danger, the instrument must be disconnected
from the power supply by simply pulling out the mains
cable.
> Always position the instrument so that the power supply plug
can be easily reached.
1. Connect the mains unit instrument plug to the mains unit
socket.
2. Connect the mains plug of the mains unit to a mains socket.
- The power supply is provided by the mains unit.
- If the testo 324 is switched off, the rechargeable battery
charging process starts automatically. Switching on the testo
324 stops the battery charging and the instrument is then
powered via the mains unit.
5.2.2. Connecting hoses/probes
> Connect the required hoses/probes at the corresponding
connections.
5.2.3. Switching on
> Press [].
When the instrument is switched on, the valves of the
testo 324 are activated. Four short acoustic signals are
output.
If fewer than 4 acoustic signals are sounded, the testo 324
must be switched on and off several times before use until
4 signals are sounded.
The testo 324 then starts up as usual.
- The start screen is displayed (duration: approx 15 s).
- If the voltage supply was interrupted for an extended period:
The Date/Time menu is opened.
- The pressure sensors are zeroed.
- If there is an instrument error, the Error diagnosis menu is
displayed.
- The Measurement options menu is displayed.
