m WARNING! READ BEFORE INSTALLATION m
1. GENERAL:
A failure resulting in injury or damage may be
caused by excessive overpressure, excessive
vibration or pressure pulsation, excessive
instrument temperature, corrosion of the
pressure containing parts, or other misuse.
Consult Omega Engineering before installing
if there are any questions or concerns.
remain full (if possible), pumps should be
brought up to power slowly, and valves
opened slowly. To avoid damage from both
fluid hammer and surges, a surge chamber
should be installed. Symptoms of fluid hammer and surge’s damaging effects:
• Digital Gauge exhibits large zero offset.
• Digital Gauge pressure display remains
constant regardless of pressure
2. OVERPRESSURE:
Pressure spikes in excess of the rated overpressure capability of the gauge may cause
irreversible electrical and/or mechanical
damage to the pressure measuring and containing elements. Fluid hammer and surges
can destroy any pressure transducer and
must always be avoided. A pressure snubber
should be installed to eliminate the damaging
hammer effects. Fluid hammer occurs when
a liquid flow is suddenly stopped, as with
quick closing solenoid valves. Surges occur
when flow is suddenly begun, as when a
pump is turned on at full power or a valve is
quickly opened.
• Error code is displayed on screen.
FREEZING:
Prohibit freezing of media in pressure port.
Unit should be drained. (Mount in vertical
position to prevent possible overpressure
­damage from frozen media.)
3. INSTALLATION:
This procedure requires the use of a 11⁄16˝
(27mm) hex wrench for tightening the instrument to the process connection. Apply
Teflon tape or a suitable sealing compound
to NPT threads of the gauge. Take using
the wrench, tighten 1 turn beyond handtight or until a leak-proof seal has been
achieved.
PRESSURE SURGES:
Surges are particularly damaging to pressure gauges if the pipe is originally empty.
To avoid pressure surges, fluid lines should
Tightening the product
m Caution:
by grasping or putting a tool on the
plastic housing can cause permanent
damage to the product.

Changing Batteries:
Grip knurled back cover and rotate counter-clockwise until the ‘unlock’ icon is in alignment with the arrow – this is on the housing at
the base of the pressure connection.
Remove cover by pulling straight back
and replace AA alkaline batteries accordingly;
ensure that the batteries are in the proper
­polarity position.
For reattachment of cover, align the ‘unlock’
icon with the arrow, push cover straight in then
turn clockwise until the arrow is in
alignment with the ‘Lock’ icon.
Note: Reinstallation of the back cover may
cause the unit to read negative pressure.
This is a temporary issue as the internal case
pressure will be relieved by the case vent and
equalize with atmospheric pressure (90% of
the offset will equalize within 1 minute, the remaining 10% may take up to 5 minutes).
