Electric Pump Considerations
The Product uses a small, battery-powered pneumatic
pump that can quickly build rated high pressure. Because
the pump has an upper pressure generation limit, there
may be atmospheric conditions where it cannot go to full-
scale pressure. High-altitude use (about 3000 ft or
1000 meters), or use at cold temperatures, can limit the
pump to about 90 % of its rated pressure. In these cases,
the vernier adjustment can be used to supply additional
pressure necessary if full-scale pressure must be
supplied.

supplied.
In these situations, start the calibration with the vernier in
the full counter-clockwise position and then, when the
electric pump reaches its limit, turn the vernier clockwise.
This will raise the pressure to set the necessary reading.

Measure Pressure
To measure pressure, connect the Product with the
correct fitting. Select a pressure setting for the display
that is used. The Product has one internal sensor 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 9 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.
