1 Read before operating for the first time
• The operating instructions should be read carefully before
the device is used and followed in every detail.
• Never take any measurements of electrically live
components
• Remain within the measuring ranges of the sensors
(overheating can lead to their destruction)
• Observe storage and transport requirements (protect the
device from direct sunlight)
• Carry out pressure equalisation only with appropriate
reference.
• When moved from one location to another with different
climatic conditions, the device needs an acclimatisation
period of several minutes.
• Technical data, storage and transport requirements can
be found on the data sheet.
• Warranty: Device, 12 months

The differential pressure models C310…C340 are equipped
with two pressure ports (P1 and P2):
In the case of C310 models, the higher pressure is
connected to P1. For all the other models, the higher
pressure must be connected to P2.
Please also observe the maximum overload on ports P1
and P2. Higher pressures may damage or destroy the
sensor.

THUMB-WHEEL
4 Operation
In contrast to conventional hand-held measuring devices, the
C3x0 devices do not have a keypad, but what is known as a
"THUMB-WHEEL" on the left-hand side of the device.
The wheel can be turned up or down through 15° and can also
be pressed in the middle position.
Turning the wheel up selects the upper menu. Turning the
wheel down selects the lower menu for configuration and
equalisation.
The thumb-wheel has to be pressed in the middle position to
switch the device on or off and to confirm input values.
