ATAGO instruments are rigorously inspected to ensure each unit meets the highest standards of quality assurance.
●Safety Instructions
Read and follow all safety instructions before operating the instrument. Failure to comply with the following instructions may
result in personal injury or property damage.
WARNING
◇Ensure safety when handling hazardous materials. Observe precautionary measures and use protective equipment, Be
aware of the hazards of such chemicals and emergency response guidelines.
◇ATAGO may not be held liable for any injury or damage arising in connection with handling of hazardous materials during
the use of the instrument.
◇Do not drop the instrument or subject it to strong physical shock.
◇Do not attempt to repair, modify, or disassemble the instrument.
Thank you for purchasing the instrument. Carefully read and follow all instructions. Keep this manual for future reference.
A small amount of solution may leak from the reference electrode. This is normal and does not affect the unit's performance.
〈International Protection Classification IP65〉
◇The instrument is water-resistant, not waterproof, and should not be submerged.
〈Chemical Resistance of Body Case〉
◇The body case is made of PBT. Do not expose it to water vapor or solvents.
◇Do not use metal tools, such as a spoon, as they may scratch
the glass electrode, resulting in erroneous measurements.
◇Do not measure organic solvents, adhesives, cement, alcohol
or hydrogen flouride.
◇Do not use water above 50℃ to rinse the instrument.
◇Only use the specified battery type. Observe proper polarities,
properly aligning the anodes and cathodes.
◇Store the instrument away from direct sunlight/heat sources
and excessive amounts of dust/debris.
◇Do not expose the instrument to a rapid change in ambient
temperature.
◇Do not subject the instrument to strong vibration.
◇Do not subject the instrument to extreme cold temperature.
◇Do not place the instrument under anything heavy.
◇Loosen the battery compartment cover for air transportation.
CAUTION
◇Carefully read this manual to have basic knowledge of
the function of each component.
◇ATAGO is not liable for any loss and damage caused by
the measurement and use of this instrument.
◇ATAGO shall not be held responsible for any or all
damages that may result from using the instrument for
those other than its intended purpose (measurement of
pH level of a liquid sample).
◇If the standard solution for calibration comes in contact
with hands or skin, immediately rinse with plenty of
water.
◇The glass electrode is fragile; be careful not to damage
it. Glass shards may cause injury.
Measurement results and remaining
battery charge are displayed.

Calibration points -1-
Calibration can be done at 3 points (pH 4.01, pH 6.86, and pH 9.18).
If the sample is above pH 6.9, calibration can be done at 2 points (pH 6.86 and pH 9.18).
If the sample is less than pH 6.9, calibration can be done at 2 points (pH 4.01 and pH 6.86).
Press the CAL button to perform calibration for either pH 4.01, pH 6.86, or pH 9.18.
＊If the power is not turned on, press the START button to turn on the power, then perform the following procedure.
Calibration points -2-
Calibration can be done at 3 points (pH 4.01, pH 7.00, and pH 10.01).
If the sample is above pH 7.0, calibration can be done at 2 points (pH 7.00 and pH 10.01).
If the sample is less than pH 7.0, calibration can be done at 2 points (pH 4.01 and pH 7.00).
Press the CAL button to perform calibration for either pH 4.01, pH 7.00, or pH 10.01.
＊If the power is not turned on, press the START button to turn on the power, then perform the following procedure.

【Caution】
◇Perform calibration before initial use and at least once a month to maintain precision and accuracy.
◇Measure a standard calibration solution. When the measurement value falls outside of the expected range, perform
calibration.
◇When the time lapsed since last measurement is more than 2 weeks, it is recommended to calibrate the instrument.
◇If the ambient temperature changes during the daily work with this instrument, it needs the calibration again.
【Caution】
◇Do not splash water above 50℃. The plastic may warp, which may compromise the water resistance.
・When measuring hot samples, place only the necessary amount and do not let it overflow from the sample stage well.
・When hot water is necessary to clean off hardened samples, use water-soaked gauze around the sample stage and keep
hot water away from the body case.
◇In rare cases, a measurement value may be displayed even if there is not sample placed on the electrode section. In such
instances, simply place some sample on the electrode section and press the START button. Measurements will be taken normally.
◇When measuring samples such as strong acids and high alkaline, take a quick measurement and rinse off any remaining
sample with tap water.

【Caution】
◇ Please remove the tape in the battery compartment before first use.
◇ Fasten the battery compartment cover tightly to prevent water ingress or poor connection,
which will cause erroneous measurements. Push the cover in firmly and turn.
◇ When the O-ring on the cover is dirty or damaged, the water resistance may be compromised.
◇ When the battery icon indicates the low power level ( ), replace both batteries with a
brand new set of AAA alkaline batteries (1.5V).
◇ Static images may occasionally appear on LCD. Such retained pixel charges do not indicate a
faulty display, consume the battery power, or affect the instrument’s performance in any way.
◇ Check the expiration dates on batteries before purchase.
◇Calibrate the instrument after the batteries are replaced.
