3. Instructions
1) Calibration: Rinse the probe in distilled water and shake off excess water. Immerse the probe in
the standard buffer solution pH7.00. Stir for a few seconds and wait for the reading to stabilize.
Then press the CAL button for about two seconds until CAL appears on the screen. When the
calibration value 7.0 flashes, the calibration will finish after several seconds, and the meter will
return to measurement mode and the icon will appear on the screen.
2) Measurement: Rinse the probe in distilled water and shake off excess water. Immerse the probe
in your sample solution. Stir the probe for a few seconds and wait for the reading to stabilize, then
record the measurement.
3) After measurement, rinse the probe with distilled water, shake off excess water, and put the
protection cap back on.
4) Storage: Always leave a bit 3M KCL storage solution in the probe cap when storing the meter as it
will optimize the performance and maximize the life of the pH probe.
5) Change temperature unit: When meter is turned off, hold the CAL button until the meter reboots
and then the temperature unit will be switched (˚C–˚F)
4. Notes
1) Calibrate the pH pen at least once a month.
2) To ensure the accuracy, make sure the pH standard buffer is fresh and clean. The small bottle of

Usage Features:

The SX610 pH Pen Tester offers straightforward operation for both calibration and measurement.

Calibration:

1. Rinse the probe with distilled water and shake off any excess.
2. Immerse the probe in a standard pH 7.00 buffer solution.
3. Stir for a few seconds and wait for the reading to stabilize.
4. Press and hold the "CAL" button for approximately two seconds until "CAL" appears on the screen.
5. The calibration value "7.0" will flash, indicating the calibration process. After several seconds, the calibration will complete, and the meter will return to measurement mode, displaying the "M" icon.

1. Rinse the probe with distilled water and shake off excess water.
2. Immerse the probe in the sample solution.
3. Stir the probe for a few seconds and wait for the reading to stabilize before recording the measurement.
4. After measurement, rinse the probe with distilled water, shake off excess water, and replace the protection cap.

Changing Temperature Unit:

When the meter is turned off, hold the "CAL" button until the meter reboots to switch the temperature unit between °C and °F.

Maintenance Features:

Proper maintenance is crucial for ensuring the accuracy and longevity of the SX610 pH Pen Tester.

Calibration Frequency:

• Calibrate the pH pen at least once a month.
• Ensure the pH standard buffer is fresh and clean for accurate results. The small bottle of pH buffer included in the kit is suitable for 5-10 calibrations.

Probe Cleaning:

• Keeping the probe clean is critical for reliable tests.
• If contaminated, clean the probe head in soap water using a soft brush.
• Rinse the probe with distilled water.
• Soak the probe in 3M KCL solution for at least 30 minutes.
• Perform calibration before using the probe again.
• If the contaminant is difficult to remove, use Apera's cleaning solution instead of soap water.

Storage:

• Always leave a small amount of 3M KCL storage solution in the probe cap when storing the meter. This optimizes performance and maximizes the life of the pH probe.
• NEVER store the probe in distilled, RO, or deionized water.

Probe Replacement:

• The typical service life of the pH electrode is approximately 12-18 months.
• If the "Err" icon appears on the screen, or if the accuracy or response speed no longer meets your requirements, replace the probe.
• The replacement probe model number is SX615. A tutorial video on how to replace the pH probe is available on support.aperainst.com.

Battery Replacement:

• Replace the CR2032 batteries when the battery icon appears on the screen.

General Notes:

• The instrument will automatically turn off after 10 minutes of inactivity.
• NEVER test samples over 60°C (140°F). Testing samples at room temperature will yield the most accurate results.
