Test procedure:
1.) Both controls , Medium and dry container, have to be closed completely
2.) Remove red seal plug and connect the gas input line at
„ Gas In“.
3.) For measurements with gases, except compressed air, the
„Gas out“ is to change to a suitable
line output.A secure gas flow out is to ensure.
4.) The tightness of all connections is to be checked and ensured.
5.) Switch on the display / datalogger. (to press switch on/off button >=3 sec )
6.) Slowly open the control "Medium", max. until the red mark is visible.
7.) Allow the gas to flow until the display shows a stable reading.
8.) Switch off the unit after completing the measurement
9.) Before disassembling the connections, the system must be vented to atmospheric pressure.
The measuring point should be as close as possible to the critical measuring point in order to obtain a
truly representative measurement. The length of the DP 400 mobile cable should be as short as
possible. Only use PTFE piping (supplied) or stainless steel.
7.2.2 Display / data logger
The display of the DP 400 mobils is at time of delivery already preconfigurated.
In addition to the pressure up to 16bar, the dew point (pressure dew point), the temperature, relative
humidity, absolute humidity (g / m³) as well as other moisture values are measured
The humidity values are indicated in display channel A1 as well as the pressure on channel B1.
The DP 400 mobile provides an optional data logger for recording the measured values. (Storage
capacity 100 million measured values)
