Crystal DiffXP - Manual (Page 2)

5 DP Measurement Mode: Change the valves as shown
in figure 3 to allow line pressure and differential pressure
measurement.
a Differential Pressure: The lower line of the right
hand (–) gauge is the differential measurement between
both gauges. Place the right hand (–) gauge in averag-
ing mode if further damping is required in the event of
erratic or noisy readings.
6 Vent: Vent left-hand (+) gauge as shown in figure 4.
Reverse both upper valves to vent the right hand (–) gauge.
7 Disconnect Connections: Disconnect connections as
appropriate.
Note: Further detailed information is available in the XP2I-DD
(Dual Display or the unit on the right side). This information
can be found at crystalengineering.net
