2-2. Warning cases
2. WARNING
Sampling point pressure
The purity meter is designed to introduce a gas of 0.1 to 0.7 MPa (gauge pressure) through
GAS IN. Do not introduce a gas that exceeds the range of 0.1 to 0.7 MPa (gauge pressure).
Otherwise, a failure may be caused.
Reference calibration in the atmosphere
When the reference calibration is performed in the atmosphere, check the atmosphere for
freshness before beginning the calibration. If interference gases (gases other than SF6 and air)
exist, the adjustment cannot be performed properly and thus correct measurement of gas
concentration may not be performed.
Use of battery
To operate the purity meter with batteries, be sure to use AA alkaline batteries of the same
type.
Replace all of the three batteries with new ones at one time.
To operate the purity meter with AC adapter, use the dedicated AC adapter (option).
Battery level check
Before use, check that there remains sufficient battery power. When the purity meter is not
used for a long period, the batteries may be exhausted. Never fail to replace them with new
ones before use.
If a battery error occurs, measurement cannot be performed. If an error is displayed during use,
turn off the power and promptly replace the batteries in a safe area.
Others
Do not throw the purity meter into fire.
Do not wash the purity meter in a washing machine or ultrasonic cleaner.
Do not block the buzzer sound opening. No buzzer sound can be heard.
Do not remove the batteries or dedicated AC adapter (option) while the power is on.

2-3. Precautions
3. CAUTION
Do not measure gases that contain interference gases.
If a measuring gas contains an interference gas (other than SF6 and air), accurate readings
cannot be obtained. Do not measure gases that contain interference gases.
Use REF. IN and end of handy aspirator under atmospheric pressure.
Use the REF. IN of purity meter and the end of handy aspirator under atmospheric pressure.
Do not use the purity meter where it is exposed to oil, chemicals, etc. Do not submerge the
purity meter under water on purpose.
Do not use in a place where the purity meter is exposed to liquids such as oil and chemicals.
The purity meter is neither water-proof nor dust-proof.
Do not place the purity meter where water or dirt gets accumulated. The purity meter placed at
such a location may cause malfunction due to water or dirt that gets into the buzzer opening,
etc.
Note that drawing in dirty water, dust, metallic powder, etc. will significantly deteriorate the
sensor sensitivities. Be careful when the purity meter is used in an environment where these
elements exist.
Do not use the purity meter in a place where the temperature drops below -10ºC or rises over
40ºC.
The operating temperature of the purity meter is -10 to +40ºC. Do not use the purity meter at
higher temperatures, humidities and pressures or at lower temperatures than the operating
range.
Do not use the purity meter in a place where the surface of it is heated above 40ºC by radiant
heat (infrared rays emitted from a high-temperature object) or direct sunlight.
Do not store the purity meter in a sun-heated car.
Observe the operating restrictions to prevent condensation inside the purity meter or
sampling hose.
Condensation formed inside the purity meter or sampling hose causes clogging or gas
adsorption, which may disturb accurate gas measurement. Thus, condensation must be
avoided. In addition to the operating environment, carefully monitor the temperature/humidity of
the sampling point to prevent condensation inside the purity meter or sampling hose. Please
observe the operating restrictions.
Do not use a transceiver near the purity meter.
