Sample label for General Purpose Smart
Manometers
All Series models are available for general-purpose use.
General Purpose (GP) versions are identified by the name plate
located on the rear of the unit under the protective rubber boot. A
sample of the General Purpose name plate is shown below:
Fire or explosion hazard
▪Do not use General Purpose versions in hazardous areas.
▪Do not use General Purpose versions in areas that may
contain flammable gas or vapors, combustible dusts or
ignitable fibers where an unintended spark can cause a fire or
explosion.
For General Purpose series
Substitution of components may impair operation and safety.
▪Disconnect power before servicing.
▪Do not power the Smart Manometer with a combination of
new and old batteries.
▪Do not power the Smart Manometer with a combination of
batteries from dierent manufacturers.

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 dierential sensors:
1. Connecting pressure to the incorrect pressure port on DN or
DI dierential pressure modules may cause damage to the
pressure sensor.
2. Applying pressure to either port before both connections are
made.
Apply pressure to both dierential 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 Oset (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 oset.

Steps for zeroing Absolute sensors
You can zero the Smart Manometer in one of three ways. The
following may appear in a dierent 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 Explanations
TAP  TO
CHOOSE REF
• Tapping the Accept key selects the displayed
reference.
ARROWS TO
CHANGE REF
• Tapping an Arrow key changes the displayed
reference.
X Cancels • Tapping the Cancel key cancels the zero
request.
ab5 0 • This is the on-screen abbreviation for
Absolute Zero.
dflt • 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.
u5Er 0 • This refers to User Defined Oset (Zero). You
can set an absolute reference point other than
zero.

How to zero Dierential 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.
