1. 서론
The Apera Instruments PH60 Pocket pH Tester is designed for reliable and easy pH measurement in general water solutions. This includes applications such as hydroponics, horticulture, aquaculture, pools & spas, water treatment, cooling towers, environmental monitoring, beverage making, and educational settings. The meter features a replaceable pH probe (PH60-E) specifically for general water solutions. It is also compatible with three other types of pH electrodes and an ORP probe (sold separately) for specialized applications like solid samples and surface tests.
메모: A few drops of 3M KCL liquid (included in the kit) should be added to low ion-strength test samples (e.g., distilled water or RO water) to significantly accelerate stabilization without affecting the pH reading.

3.2 초기 프로브 준비
Before first use or if the tester has not been used for a long time (over 1 month):
- Pull out the battery insulation slip (if present) and remove the probe cap.
- Rinse the probe thoroughly with pure water (preferably distilled or deionized water, RO water is acceptable). Shake off excess water.
- If the tester hasn't been used for a long time (over 1 month), soak the probe in the 3M KCL soaking solution (included in the kit) for 15 minutes.
- Proceed to calibrate the meter before testing.

4. 사용 설명서
4.1 pH 교정
The PH60 tester features 1-3 point automatic calibration with auto-buffer recognition. Always calibrate pH 7.00 first. If you need to calibrate pH 4.00 or pH 10.01, do so immediately after pH 7.00 calibration. Do NOT turn the meter off between pH 7.00 and pH 4.00/10.01 calibrations.
- Pour pH buffer solutions (pH 4.00, pH 7.00, pH 10.01) into the corresponding calibration vials to about half volume.
- 프로브를 순수한 물로 헹구고 과도한 물을 털어냅니다.
- Short press the power button to turn on the tester.
- Dip the probe into the pH 7.00 buffer solution. Make a quick stir, then let it stand.
- Long press the 'CAL' button to enter calibration mode. The screen will turn green.
- Wait for the reading to stabilize (a smiley icon will appear on the screen), then short press 'CAL' to finish the first point calibration. The tester will return to measurement mode, and an 'M' icon will appear at the bottom left, indicating a successful first-point calibration.
- Without turning off the tester, rinse the probe and repeat steps 4-6 for pH 4.00 buffer solution. An 'L' icon will appear for successful 2-point calibration.
- Without turning off the tester, rinse the probe and repeat steps 4-6 for pH 10.01 buffer solution. An 'H' icon will appear for successful 3-point calibration.

4.2 pH 측정
To take a pH measurement:
- Short press the power button to turn on the tester.
- 프로브를 순수한 물로 헹구고 과도한 물을 털어냅니다.
- Insert the probe into your sample solution, make a quick stir, and hold still.
- Take the reading as the measurement when it is fully stabilized (a smiley icon appears and stays on screen).
- If the Auto-Hold function is turned on (in parameter setting P4), the reading will be automatically locked when it's stable for more than 10 seconds. The 'HOLD' icon will stay on. Short press the 'CAL' button to cancel Auto-Hold and continue measuring.
- Short press the 'MODE' button to switch to mV mode, which is for ORP testing or technical analysis (an ORP probe is needed for ORP measurements).

5. 유지관리
5.1 프로브 청소
The accuracy of the tester depends on the cleanliness of the probe. Always thoroughly rinse off the probe before and after each measurement with pure water.
- For tough contaminants, detach the sensor shield.
- Soak the probe in Apera probe cleaning solution (SKU: AI1166) or detergent water for 30 minutes.
- Use a soft brush to gently remove contaminants.
- Rinse the probe off with pure water and reattach the sensor shield.
- After cleaning, soak the probe in 3M KCL soaking solution for 1 to 2 hours.
- Re-calibrate the tester before using it again.

5.2 프로브 저장
Proper storage is crucial for maintaining probe longevity and accuracy.
- For regular storage (daily or weekly usage): Ensure there are a few water droplets inside the probe cap to maintain humidity. Close the probe cap tightly to prevent drying out.
- For long-term storage (no use >1 month): Store the probe in the 3M KCL soaking solution.
IMPORTANT: NEVER store the probe in pure water (like tap, RO, distilled, or deionized water) as they could damage the pH sensor. If this happens, immediately soak the pH probe in the 3M KCL soaking solution overnight to restore. Then re-calibrate it before using. Pure water is only for rinsing off the probe, NOT for storage.

6. 문제 해결
다음은 몇 가지 일반적인 문제와 해결 방법입니다.
- Water droplets inside the electrode cap: This is normal for a new product. It is added before the product leaves the factory to maintain the sensitivity of the electrode.
- 부정확하거나 불안정한 측정값: Ensure the probe is clean and properly calibrated. If the probe has been stored dry, soak it in 3M KCL solution for at least 15 minutes before re-calibrating.
- Meter not powering on or display issues: AAA 배터리가 올바르게 장착되었는지, 그리고 충전량이 충분한지 확인하십시오. 필요한 경우 배터리를 교체하십시오.
- Calibration failure: Ensure you are using fresh, uncontaminated calibration solutions. Always calibrate pH 7.00 first, then proceed with pH 4.00 or pH 10.01 without turning off the meter.
