A. Safety advice
Avoid electrical hazards:
Never use the measuring instrument and probes to measure on or near live parts!
Protect the measuring instrument:
Never store the measuring instrument/sensors together with solvents
(e.g. acetone). Do not use any desiccants.
Product with Bluetooth® (Option)
Changes or modifications, which are not expressly approved by the responsible official
body, can lead to a withdrawal of operating permission.
Interference with data transfer can be caused by instruments which transmit on
the same ISM band, e.g. microwave ovens, ZigBee
The use of radio connections is not allowed in e.g. aeroplanes and hospitals. For this
reason, the following point must be checked before entering:
Deactivate Bluetooth function
Inst’ settings Communication Select IrDA
Product safety/
preserving warranty claims:
Operate the measuring instrument only within the parameters specified in the Techni-
cal data.
Handle the measuring instrument properly and according to its intended purpose.
Never apply force!
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.
Open the measuring instrument only when this is expressly described in the instruc-
tion manual for maintenance purposes.
Carry out only the maintenance and repair work that is described in the instruction
manual. Follow the prescribed steps exactly. For safety reasons, use only original
spare parts from Testo.

A. Safety advice 7

Any 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.
Ensure correct disposal:
Dispose of defective rechargeable batteries and spent batteries at the collection
points provided for that purpose.
Send the measuring instrument directly to us at the end of its useful life. We will ensu-
re that it is disposed of in an environmentally friendly manner.

B. Intended purpose
This chapter describes the areas of application for which the measuring instrument is
intended.
The testo 340 is a handheld measuring instrument used in professional flue gas analysis
for:
· Engineers servicing/monitoring industrial combustion plants (process systems, power
stations)
· Emissions inspectors
· Engine manufacturers and operators
· Service engineers/mechanics of burner/boiler manufacturers in the industrial sector
Typical measuring tasks and particular characteristics of the testo 340 include:
· Measurement on industrial engines (CO/NO dilution)
· Measurement on gas turbines (high precision CO and NO plus optional dilution)
· Emissions measurement (integrated flow speed and differential pressure measurement)
testo 340 should not be used:
· for continuous measurements > 2 h
· as a safety (alarm) instrument
The testo 340 with the Bluetooth option may only be operated in countries in which it
is type approved (see Technical Data).
