is high and condensation occurs. If water gets inside thid unit, it may cause a
malfunction, electric leakage, or fire.
Ensuring ventilation
Do not put this unit in a closed container, and be sure to install it in a well-
ventilated place. If sealed, the temperature of the electronic components inside the
power supply will rise, which may shorten the service life.
Excessive pressure in the vacuum chamber
Do not connect to a place where t
he pressure inside the sensor exceeds atmospheric
pressure. It may cause harm to the surroundings including the human body, such as
damage to the sensor or popping out of the sensor from the connection. When the
pressure exceeds the atmospheric pressure, i
nstall an isolation valve so that the
pressure inside the sensor does not exceed the atmospheric pressure.
Use in a corrosive gas atmosphere
When exposed to corrosive gas or chemically active gas such as halogen or halogen-
based gas, problems such as disc
onnection of filaments and changes in pressure
characteristics occur. When using in such an environment, install an isolation valve
between this unit and the vacuum chamber to protect it from exposure to these gases
as much as possible.
Use in a CVD gas atmosphere, etc.
When exposed to CVD (Chemical Vapor Deposition) raw material gas or gas that
accumulates such as oil mist of rotary pumps, problems such as disconnection of
filaments and changes in pressure characteristics occur. When using in such an
envi
ronment, install an isolation valve between this unit and the vacuum chamber to
protect it from exposure to these gases.
Moisture and deposits
If there are many deposits such as water and organic matters that gradually evaporate
in the sensor, it will aff
ect the pressure accuracy and response speed on the vacuum
side in particular. Please consider the installation location and method so that
deposits do not adhere.
Influence of magnetic field
Due to the influence of a magnetic field of 0.01T (100Gauss), t
he pressure indication
on the atmospheric pressure side is affected by about 10%. If this unit is affected
by a magnetic field, install a magnetic shield.

SK00-9662-EI-103-00

Temperature fluctuation
According to the measurement principle of pirani vacuum gauge, the ambient t
emperature
of the sensor affects the measured value. Pay attention to the mounting position so
that the ambient temperature does not deviate significantly from the temperature at
the time of calibration (about 25℃).
Influence of electrons, ions, etc.
If t
here is a strong source of electrons or ions nearby, not only will the correct
pressure not be measured, but it may also cause damage or malfunction of this unit.
Please be careful about the mounting position so that it will not be affected by
electrons or ions.
Foreign matter intrusion
Protect the inside of this unit from the opening to prevent foreign matter such as
metals and flammable materials from entering.
Impact
Do not give a shock to this unit. The impact may cause the filament to disconnection,
the sensor to leak, or the mounting part to be damaged.
2.2. Precautions on power supply
Precautions when laying cables
Make sure that the connection cable to each pin does not come into contact with other
pins or cases. Also, be careful not to make a mistak
e in the pin sign. Incorrect
connection may cause damage to this unit and the devices connected to this unit, or
cause a fire.
Power supply voltage
Before turning on the power, check that the working voltage of this unit and the power
supply are correct.
Connecting the wrong power supply may damage this unit and the
devices connected to this unit, or cause a fire. In particular, do not apply a voltage
exceeding DC 30V.
Power on
Turn on the power after connecting all the sensor, display, evaluation unit, c
able,
etc. to this unit. Doing so may damage this unit or the equipment connected to this
unit or cause a fire. In addition, the filament of the sensor may be disconnected.
2.3. Precautions on installation of this unit
Protective ground
Be sure to electrical
ly connect this unit to a grounded vacuum chamber. Use a
conductive metal clamp for the NW flange. If it is not grounded properly, not only
will it not show the correct pressure, but it may also damage this unit and the
equipment connected to it, or cause
a fire. When insulating from the vacuum chamber,
ground the case part (D-sub connector shell part) to D type (3types).

Temperature fluctuation
According to the measurement principle of p
irani vacuum gauge, the ambient temperature
of the sensor affects the
measured value. If the ambient temperature deviates
significantly from the temperature at the time of calibration (about 25℃), adjust the
atmospheric pressure and zero point.
Influence of magnetic field
Due to the influence of a magnetic field of 0.01T (
100G) on this unit, the pressure
indication on the atmospheric pressure side is affected by about 10%. If this unit is
affected by a magnetic field, install a magnetic shield.
Fixing method
Fix the cable so that the connection part of the cable is not app
lied as much as
possible. Also, Make sure to insert the unit cable
Vibration
Since the filament of the pirani sensor is as thin as φ25μm, avoid using it in a
place with a lot of vibration as much as possib
le. Also, the biggest cause of
disconnection is due to mechanical shock, so please be careful about the installation
location and handling.
Mounting position
Pressure measurement measures the static pressure at the position where the sensor
is connected. When installing in an environment where there is a flow in the vacuum
system, a source of emitted gas/electrons, a strong source
of ions, or a magnetic
field, pay attention to the selection of the measurement position and install it in a
position where there is little influence.
Gas flow in the measurement system
Pressure measurement measures the static pressure at the position wh
ere the sensor
is connected. Make sure that the sensor mounting opening surface is parallel to the
gas flow. In particular, make sure that gas does not enter the sensor in a beam shape.
Also, pay attention to the mounting position so that it will not be affected by outgas.
Outgas
Use an O-ring with less outgas when attaching the sensor
. If a material with a large
amount of outgas such as a rubber tube or grease is used to connect the sensor
, it
will cause an error and shorten the service life.
Since it is vulnerable to vibration in the X/Y
direction, install it so that vibration is not
applied in the X/Y direction.

4. Zero point adjustment and atmospheric pressure adjustment
This unit can measure more accurately by adjusting the zero point and atmospheric
pressure.
If there is a discrepancy between the indicated value on the atmospheric pressure side
or the zero point side, adjust according to the following procedure.
4.1. Adjusting method
Zero point adjustment and atmospheric pressure adjustment can be performed with UL-
MOBI by connecting an Android/Windows device with UL-MOBI installed to SWU10-U with a
USB cable.
Based on the signal from the sensor, it automatically determines whether to perform
zero point adjustment or atmospheric pressure adjustment.
Zero point adjustment
If the adjustment is performed immediately after the pressure drops below 1×10-2Pa,
the temperature inside the sensor is not in equilibrium and the error may increase.
Also, do not disconnect the USB cable connected to the Android/Windows devices until
the adjustment is completed.
The adjustment range is about ±1Pa in the unadjusted state. If the adjustment is not
possible, the life of the sensor may be due to dirt on the filament.
①Exhaust the vacuum chamber.
②Use a vacuum gauge such as an ionization vacuum gauge and check that the pressure
in the vacuum chamber is 1×10-2Pa or less.
③Keep it at 1×10-2Pa or less for 5minutes or more.
④Make adjustments.
Atmospheric pressure adjustment
If the adjustment is performed immediately after the vacuum state changes to 1×10+5Pa,
the temperature inside the sensor is not in equilibrium and the error may increase.
Also, do not turn off the power of this unit until the adjustment is completed.
The adjustment range is about 1×10+4Pa to 2×10+5Pa in the unadjusted state. If the
adjustment is not possible, the life of the sensor may be due to dirt on the filament.
①Flow nitrogen gas into the vacuum chamber.
②Using a vacuum gauge such as a diaphragm vacuum gauge, check that the pressure in
the vacuum vessel is 1×10+5Pa.
③Keep it at 1×10+5Pa or less for 5minutes or more.
④Make adjustments.

4.2. Adjustment clear
By clearing the atmospheric pressure adjustment and zero point adjustment, you can
return the atmospheric pressure adjustment and zero point adjustment to the factory
adjustment values. To clear the adjustment, connect the Android/Windows devices in which
UL-MOBI is installed to the SWU10-U with a USB cable, and perform it with UL-MOBI.
*CAUTION*
Adjustment clear
When you clear the adjustment, both the atmospheric pressure
adjustment and the zero point adjustment are cleared. Please note
that you cannot clear either one, such as adjusting the
atmospheric pressure only or adjusting the zero point only.
4.3. Memory function
The atmospheric pressure adjustment value and zero point adjustment value are stored
in memory even if the power of this unit is turned off. However, if it will not be used
for a long period of time, it is recommended to adjust it when using it again.
