Conducting Pressure Measurements; Medium Pressure Measurement With Pump Function - Dräger P7-TD Instruction Manual

7.2 Conducting pressure measurements

Connect the test nipple on the pressure tank or pressure line
to be measured to the corresponding pressure inlet of the
measuring device using a pressure hose. For high pressure
measurements, connect the pressure tank or line to be
measured to the external high pressure sensor using an
adapter.
The left side of the display shows the current measurement
with its measurement unit, the right side shows a diagram
with the current pressure curve.
The following functions can be selected:
Zero = the measured value shown is set to zero
(not ext. sensor)
Damp = selection of the damping value (not ext. sensor)
START = start the pressure measurement
ESC = ends the pressure measurement
After the pressure measurement is started, the current pres-
sure, the starting pressure, the difference to the starting
pressure, the mean value of the measurement and the dura-
tion of the current measurement are shown.
After completion of the measurement, the result display and
documentation menu open.

7.3 Medium pressure measurement with pump function

Prior to the medium pressure measurement, a pressure of up
to 150 hPa (mbar) can be built up using the installed pump.
Then, a medium pressure measurement can be made.
