Sensors
Overview of sensors
The Smart Manometer can display two measurements: one from
the internal sensor and one from the optional tether sensor.
▪ P1 on this Smart Manometer always refers to the internal
sensor.
▪ P2 on this Smart Manometer always refers to the external
sensor.
Use two wrenches to install or remove pressure connections
Connection: 1/8” female NPT, 316L SS.
▪ Always use a 3/4 in. wrench on the pressure manifold when
you install or remove the 1/8 in. NPT fitting.
▪ Applying torque to the manifold can damage the plastic
enclosure and voids the warranty.
▪ Do not over tighten.
Carefully equalize the pressure
Avoid these two issues with dierential sensors:
1. Connecting pressure to the incorrect pressure port on DN or
DI dierential pressure modules may cause damage to the
pressure sensor.
2. Applying pressure to either port before both connections are
made.
Apply pressure to both dierential ports at the same time.
Note: See Overrange limit in the section called Specifications
concerning overrange pressure limits. If over pressure damage
occurs, you must return the Smart Manometer to the factory for
sensor replacement.

How to zero Absolute sensors
Overview of the zeroing Absolute sensors
The Smart Manometer is a stable and precise instrument.
However, on occasion the Smart Manometer should have a new
zero taken. The new zero removes a zero drift that can occur after
the Smart Manometer was last zeroed. The Smart Manometer can
be zeroed only if the new applied zero is within ± 1 % FS of the
original factory calibration zero. This prevents accidental zeroing
at atmospheric pressure or other relatively high pressures. If the
Smart Manometer is outside this limit, the Smart Manometer
cannot zero.
1. Referenced to Absolute Zero - This traditional and preferred
method takes a snapshot of the measured pressure when a
vacuum of less than 100 microns Absolute is applied to the
sensor.
2. Restore Factory Zero - This method restores the calibration
curve to the original zero taken at the factory.
Note: This feature is intended for comparison purposes, and
should not be used for real pressure measurement. This feature
does not compensate for any zero drift.
3. User Defined Oset (Zero) - With this method, you can enter
any pressure value when a known reference is applied (for
example, the local barometer). The Smart Manometer will
compare its actual measured value with the entered value, and
calculate a new zero reference based on the oset.

Steps for zeroing Absolute sensors
You can zero the Smart Manometer in one of three ways. The
following may appear in a dierent order depending on which
arrow key you press. When an absolute sensor displays on-screen
as P1 or P2, press the Zero key to see one of the three sets of
characters below and the following three messages
On-screen
message
TAP TO
CHOOSE REF
ARROWS TO
CHANGE REF

Explanations
• Tapping the Accept key selects the displayed
reference.
• Tapping an Arrow key changes the displayed
reference.
• Tapping the Cancel key cancels the zero
request.
• This is the on-screen abbreviation for
Absolute Zero.
• This is the on-screen abbreviation for Default.
• If you want to restore the Factory Zero on a
sensor, press the Accept key when you see
these characters appear.
• This refers to User Defined Oset (Zero). You
can set an absolute reference point other than
zero.
User Manual for Smart Manometer

M20011 REL-0000 (2103)
How to zero Dierential or Compound sensors
1. Disconnect from a pressure source and vent the pressure port
to atmosphere.
1. Do not remove the factory installed P2 plug if it is present.
2. The display should read close to zero.
2. Press the Zero key.
The top line displays dashes ------.
3. The process is complete when the Smart Manometer returns
to the Home (Measurement Units) screen.
4. If someone has turned on the Password Required For Future
Access feature in HHP400 Suite, the password feature does
not prevent you from zeroing the Smart Manometer.
Note: You can only zero the Smart Manometer if the new zero
value is within ± 5 % (of FS) of the original factory calibrated
zero. If the zero procedure generates a new zero reference
outside this limit, the procedure fails. Factory service may be
required.
5. You can turn o the Zero function in HHP400 Suite by
deselecting Allow zero adjust (Ø) in the Display Functions list.

Customer calibration
You can calibrate the manometer in the field for
1. Zero.
2. Span.
3. Linearity.
The customer calibration does not replace the Factory Lab
Calibration Procedure. It is intended to correct the curve fit if the
actual sensor characteristics change slightly over time.
For sensors up to 200 psi, Omega recommends a ± 0.0015% of
reading deadweight tester. For sensors 200 psi and above, a ±
0.0030 % of reading deadweight tester is recommended. Note that
AI type sensor requires absolute referenced deadweight testers or
standards for field calibration. The options are:
1. 2-point (within upper 50% of FS)
2. 5-point (nominal values of 0%, 25%, 50%, 75% and 100% of
FS).
3. Restore factory default calibration.
For the 5 Point calibration, points 2, 3 and 4 can be adjusted
within ± 1% of reading around the nominal values. Point #5 can be
adjusted within -1% of reading around nominal. Point #1 is fixed.
The unit can only be calibrated if the calibration points are within
5 times the accuracy of the original factory calibration
For example: at 0.05% accuracy, the point limit is ± 0.25% of
FS.
If the calibration procedure generates a new value outside this
limit the procedure fails. In this case the unit would need to be
returned to the factory for service.
After a calibration has been performed (either 2-point or
5-point), the sensor uses only that calibration. To turn on another
calibration type, you must first Restore Factory Defaults and then
choose another calibration method.

energy in the frequency range 130-1000 MHz and 1.6-2.1 GHz, the
pressure and temperature readings may fluctuate beyond the
published tolerance of each respective value being measured. In
the event of such a phenomenon occurring, the operator should
move away from (or have removed) any source of strong RF
emissions such as radio transmitters, cell-phones, etc., and repeat
the measurement, or reconnect to a PC.
Electrostatic discharge (ESD)
This unit is sensitive to ESD discharges that may result in the
unit re-starting of the operating system, or interruption of a PC
connection. In the unlikely event of such an occurrence, users
should ensure they discharge any static charge they may be
carrying by touching a known grounded conductive surface prior
to operating the equipment .
