Application Example
Confirmation of air line
source pressure
Courtesy of Steven Engineering, Inc.-230 Ryan Way, South San Francisco, CA 94080-6370-Main Office: (650) 588-9200-Outside Local Area: (800) 258-9200-www.stevenengineering.com
Human reading error is eliminated by
the ability to confirm line pressure on
the digital display.
It is also possible to check pulsation in
the source pressure using the peak/bottom display funcion.
Confirmation of regulator
set pressure
Setting a regulator can be performed
more precisely than with a dial
gauge by viewing the digital display
while making the setting.
Furthermore, power lines are not
needed for this battery operated unit.

Precautions
Be sure to read before handling. Refer to pages 14-21-3 to 14-21-4 for Safety Instructions and Common
Precautions.
Handling
Operating Environment
1. The compact manometer can be used for
measurement of air and non-corrosive gases.
1. Absolutely never use in an atmosphere where
explosive gases are used.
Please note that the accuracy of measurement for other fluids
cannot be guaranteed. Furthermore, the construction is not
explosion proof, and therefore, flammable gases should not
be used.
The compact manometer does not have explosion proof
construction. If used in an atmosphere of explosive gases,
there is a possibility of causing an explosion, and therefore,
should absolutely not be used under these conditions.
Warning
2. Be certain to stay within the rated pressure range.
Operation outside the pressure range will cause failure.
Warning
Caution
Courtesy of Steven Engineering, Inc.-230 Ryan Way, South San Francisco, CA 94080-6370-Main Office: (650) 588-9200-Outside Local Area: (800) 258-9200-www.stevenengineering.com
1. Do not use where there is splashing of water or oil,
etc.
If the strap breaks or comes loose, there is a danger of injury
or damage, etc.
The compact manometer is not a dusttight and dripproof type,
and should not be used where there is splashing water or oil,
etc., as this may result in a malfunction.
If tubing is disconnected while the fluid to be measured is in a
pressurized state, the tubing may jump causing a danger of
injury or damage. Also when connecting tubing, confirm that it
is securely attached.
5. Instruction manual
Read it carefully and understand the contents before using a
product. Also, keep the manual in a location where it can be
referred to at any time.
Caution
1. Perform maintenance and inspection on a regular
basis.
If there is an unintended misaction, misoperation, etc., or
calibration has not been performed, there is a possibility of an
incorrect value being displayed, making it impossible to
ensure safety.
2. Do not disassemble or modify the unit.
Do not use batteries other than the above, as this may cause
failiure.
When perfoming the zero clear function, this should be done
with piping ports in an atmospheric release condition. If
adjustment is performed at a pressure other than atmospheric
pressure, the correct value will not be displayed.
4. Tighten One-touch fittings in accordance with the
following.
One-touch fittings should first be tightened by hand, and then
further tightened approximately 1/6 of a turn using a tightening
tool. If screwed in too far, this may cause air leakage due to
breaking of threads or distortion of the gasket, etc. If not
screwed in far enough, this may cause a loose fitting or air
leakage, etc.

Caution
If condensate or foreign matter is mixed in the fluid to be
measured, this may cause failure or air leakage.
If there is a possibility of these being contained in the fluid,
use the meter via a filter or mist separator.
3. Be certain to perform the zero clear function with
pressure released to the atmosphere.
AR
AMR
Warning
1. Use manganese type AA dry batteries (R6) or
alkaline type AA dry batteries (LR6).
Do not drop, strike or apply a large impact shock (980 m/s2),
as this may result in a failure.

Maintenance and Other
1. Keep condensate and foreign matter from getting
into the fluid to be measured.
2. Do not drop or strike the unit, etc.
AV
AF
3. Do not intentionally swing around by the hand
strap.
4. When installing or removing One-touch fittings on
tubing, first confirm that the fluid to be measured is
at atmospheric pressure.
F.R.L.
2. Insert the plus (+) and minus (–) terminals of the
batteries in the proper direction as indicated inside
the unit.
If the batteties are inserted incorrectly, this may cause them to
leak or explode and result in damage to the unit.
3. Do not use old and new batteries or mix different
types of batteries together.
This may cause batteries to leak and result in damage to the
unit.
4. Remove the batteries when the unit will not be
used for a long period.
5. Do not use batteries if their voltage has dropped.
Continuing to use them may lead to the display of incorrect
values.
6. Do not touch the span calibration trimmer except
when performing span calibration.
Touching the trimmer may cause generation of an error in the
measured pressure. Also do not turn it too hard (0.3 N·m or
less) or press it too hard (5 N or less).
7. Use a soft cloth to wipe the blot off of the body.
In case of heavy soiling, wipe it off with a cloth soaked in a
neutral detergent diluted with water after wringing it out
thoroughly, and finish up by wiping with a dry cloth.

Error Correction
Maintenance
When errors occur, they should be corrected as shown below.

Contents
Corrective action
Pressure being applied is
above the rating.
Operate within the rated
pressure range.
Memory data has probably
been corrupted in some way.
Perform auto zero adjustment.
Battery voltage is low.
Replace the batteries.
앬 Span calibration method
Caution
Do not touch the span calibration trimmer except when
performing span calibration.
1. Perform zero clear at atmospheric pressure.
2. Apply the maximum rated pressure, and calibrate the span while
comparing with a standard pressure gauge.
3. If the display value of the compact manometer is “0” after returning
to atmospheric pressure, then calibration is complete.
If the display value is not “0”, calibrate again by repeating steps 1
and 2.

앬 Replacing the batteries
When battery voltage becomes low the entire LCD will flash.
When the LCD flashes replace the batteries. Use 2 pcs. of type AA
dry batteries.
Caution
To replace the batteries, turn the power OFF and replace them
within approximately 30 seconds.
When not completed within 30 seconds, “Err” will be
displayed. In that case, perform zero clear once again.
In the event that the display runs out of control, remove the
batteries for one minute or longer, and then perform zero clear
again for inserting the batteries and turning on the power.
