Specific Product Precautions
Be sure to read before handling.
See page 6 for safety precautions.
1. The compact manometer can be used for
measurement of air and non-corrosive gases.
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.
2. Be certain to stay within the rated pressure
range.
Operation outside the pressure range will cause failure.
3. Do not intentionally swing around by the
hand strap.
If the strap breaks or comes loose, there is a danger of injury or
damage, etc.
4. When installing or removing One-touch
fittings on tubing, first confirm that the fluid
to be measured is at atmospheric pressure.
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 the manual carefully and have a good understanding of its
contents before using the product . Also keep it where it can be
readily referred to as needed.
Handling Precautions
Warning
1. Keep condensate and foreign matter from
getting into the fluid to be measured.
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.
2. Do not drop or strike the unit, etc.
Do not drop, strike or subject to a large impact shock (1000/s
2
), as
this may cause failure.
3. Be certain to perform the zero clear function
with pressure released to the atmosphere.
When performing 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
the threads or distortion of the gasket, etc. If not screwed in far
enough, this may cause a loose fitting or air leakage, etc.
Caution
1. Absolutely do not use in an atmosphere of
explosive gases.
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.
Operating Environment
Warning
1. Do not use where there is splashing of water
or oil, etc.
The compact manometer is not a dust proof and drip proof type
and should not be used where there is splashing of water or oil,
etc., as this may cause failure.
Caution
1. Perform maintenance regularly.
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.
Maintenance & Other
Warning
1. Use manganese type AA dry batteries (R6) or
alkaline type AA dry batteries (LR6).
Do not use batteries other than the above, as this may cause
failure.
2. Insert the plus (+) and minus (-) terminals of
the batteries in the proper direction as
indicated inside the unit.
If the batteries 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 (0.3N•m or less) or
press it too hard (5N or less).
7. Use a soft cloth to clean the case.
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.
