Page 12 of 12
NOTICE:
All of the parameters are recorded in the memory.
If an error is detected at power up, the display indicates « Config. Error. Code :X » where X represents an error
code (0 if error is on the zero setting, 1 if error is on the measurement scale; if a problem occurs, contact us).
In the event of a defect, the outputs 4-20mA are 0mA
CALIBRATION:
The device leaves our workshops, calibrated at 0, for zero pressure and at the maximum for the maxi pressure value
of the range. Settings done, device stabilised and at 20° C.
It is possible to adjust the zero pressure:
- put the device off-pressure (disconnect both pressure inlets)
- in the pressure display mode, press the « left » button and keep it pressed
- press the « valid » button
- release the buttons: zero is set
MAINTENANCE:
The device does not require any special maintenance. However, to ensure the measurements are precise, an annual
calibration is recommended especially with regard to « zero » (see CALIBRATION).
WARRANTY:
The DBX2000 has a 2-year warranty (equipment returned to our workshops). The warranty does not apply in the
following cases:
- breakage through dropping or knocks to the unpackaged products,
- damage caused by abnormal use (connecting error, surge, etc.)
- any work on the device apart from the connections
For ATEX devices :
No intervention can be done on the device: this one must be sent back to our workshop. Otherwise, it may lose its
homologation and warranty.
The unit must be returned to the following address:
CONFORMITY:
The DBX2000 device respect the European directives ( CEM and ATEX ), which concerns it.
However, it must be used correctly in applications for which it is intended, and should be linked or near CE
approved products.
WE RESERVE THE RIGHT TO MAKE ANY CHANGES TO OUR DEVICES THAT WE CONSIDER APPROPRIATE.
