6. Commissioning, operation
To achieve the maximum pumping capacity, the spring above the knurled
nut must be relaxed.
For test items with low measuring ranges, the stroke path can be reduced
by turning the knurled nut. This will reduce the pressure increase per
stroke and minimize the risk of the overpressure.
WIKA operating instructions calibration system, model BCS10
Switch on the calibration system.
The measurement setup shall be now as in the figure.
Actuate the pump handles several times until the
desired pressure is slightly exceeded.
Set the desirede pressure via the fine-adjustment
valve (arrow).
Normally, the test is carried out when the pressure falls
because the gas density measuring instruments are
generally specified and adjusted in such a way.
To reduce the pressure, turn the fine-adjustment valve
counterclockwise.
Further reduction of the pressure is possible by means
of the pressure relief valve.
To increase the pressure, turn the fine-adjustment
valve clockwise.
Use the digital pressure gauge to read the set pressure.
