2.2. Ensure safety
> The testo 320 basic must be checked before commissioning
for any visible damage. Do not commission the testo
320 basic if there are signs of damage on the housing,
mains unit or supply lines. Electrical risk.
> 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.
> The testo 320 basic is not suitable for long-term measurements
and should not be used as a safety (alarm) instrument.
> 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.
2 Safety and the environment

> 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.
> 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.
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
The testo 320 basic is a handheld measuring device for the
professional flue gas analysis of combustion plants:
• Small combustion plants (burning oil, gas, wood, coal)
• Low-temperature and condensing boilers
• Gas water heaters
These systems can be adjusted using the testo 320 basic and
checked for compliance with the applicable limit values.
The following tasks can also be carried out with the testo 320 basic:
• Regulating the O2, CO and CO2 values in combustion plants
for the purpose of ensuring optimal operation.
• Draught measurement.
• Measuring and regulating the gas flow pressure in gas water
heaters.
• Measuring and optimising the flow and return temperatures of
heating systems.
