1. Basic safety information
Avoid electrical hazards:
Never take measurements with the instrument and its probes on or near live components unless the instrument is expressly approved for current and voltage measurements.
Protect the instrument:
Never store the unit together with solvents (e.g. acetone).
Preserving product safety/warranty entitlement:
Do not blow into the pressure connections!
Operate the instrument only within the parameters specified in the Technical data.
Handle the instrument appropriately and according to its intended purpose.
Never apply force!
Protect measuring instruments from direct sunlight!
Avoid use in corrosive gases.
Do not seal off inputs (otherwise barometric pressure changes could damage instru-
ments with low measurement ranges).
Temperature data on sensors/probes refer only to the measurement range of the sen-
sors. Do not subject handles and lines to temperatures greater than 70°C if they are
not expressly approved for higher temperatures.
Open the instrument for maintenance and repair purposes only if specifically described in the Instruction Manual.
Maintenance work should only be carried out if described in the Instruction Manual.

2. Intended use
2. Intended use
The testo 6341 / testo 6343 / testo 6349 pressure transmitters are pneumatic electrical transmitters for pressure measurement (positive, negative and differential pressure).
The most important part is a pressure cell with a membrane made of beryllium bronze
which is moved between the two chambers of the pressure cell in accordance with differential pressure. The movement is measured without contact via an inductive displacement transmitter. The instruments do not have any frictional or mechanical wearing
parts.
