ATAGO instruments are rigorously inspected to ensure each unit meets the highest standards of quality assurance.
Introduction
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.

Important: Please Read and Follow Instructions Carefully Before Initial Use

Place plenty of tap water and leave it for a while.
※Dry electrodes will result in abnormal measurement values.

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).
Sample stage 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.
Apply samples on the electrode in
the center of the sample stage.
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).

【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.
Additional refills of standard solutions for calibration can be purchased from ATAGO (sold separately).

【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.
