Measure Pressure
To measure pressure, connect the Product with the
correct fitting and select a pressure port. The Product has
two internal sensors and many optional external sensors
(EPMs) are available. Make sure to choose the sensor
based on working pressures and accuracy.
Warning
To prevent personal injury:
• Pressure sensors can be damaged
and/or personnel injury can occur due to
improper application of pressure. Refer
to Table 4 for information on
overpressure and burst pressure ratings.
Vacuum should not be applied to any
gauge pressure sensor. The Product
display shows “OL” when an
inappropriate pressure is applied. If “OL”
is shown on any pressure display, the
pressure should be reduced or vented
immediately to prevent Product damage
or possible personnel injury. “OL” is
shown when the pressure exceeds 110 %
of the nominal range of the sensor or
when a vacuum in excess of 2 PSI is
applied on gauge range sensors.
