ATTENTION

  • Water droplets are added during production to maintain the moisture of the probe. This is normal practice and should not be attributed to used product.
  • Never use the product when it’s freezing cold. Let it warm to room temperature before using.
  • The latest PC60 Tester comes with an upgraded probe structure equipped with a sensor shield that prevents glass bulb breakage from accidental collisions (see picture below). Users can remove the shield when cleaning the sensor and put it back on after cleaningAPERA Premium Series PC60 5-in-1 Tester User Manual  & troubleshooting 2

Notes about Calibration

  • The 1st point calibration must be 7.00 pH. Perform the 2nd and 3rd point  calibrations (4.00, 10.01, 1.68,or 12.45) immediately after the 1st point calibration is finished. Do NOT turn off the meter before you calibrate 2nd or 3rd point. Otherwise, you will need to restart the calibration  process with 7.00 pH first.
  • The pH 4.00 and 7.00 buffer solutions poured into the calibration vials can be used for up to 10 times as long as they are not contaminated and the bottles are capped when not in use. pH 10.01 can only be used for up to 5 times as it will lose its accuracy much faster. After that, replace the buffer solutions in the calibration vials with new ones to keep the accuracy. Keeping the freshness and cleanliness of calibration buffers is essential for accurate pH measurement.
  • The tester can perform 1 to 3 points of automatic calibration and can recognize 5 types of pH standard solutions. For details, please refer to the following table

 pH Measurement

  1. How to take pH measurements
    Short press APERA Premium Series PC60 5-in-1 Tester User Manual  & troubleshooting 30 to turn on the tester. Rinse the probe in distilled water, shake off excess water. Insert the probe in your sample solution, make a  quick stir and hold still. Record the reading when it is stabilized( APERA Premium Series PC60 5-in-1 Tester User Manual  & troubleshooting 31appears and stays on screen).
  2. Pure Water pH Measurement
    When testing pure water like tap water, drinking water, RO water and distilled water, it will take longer for the readings to get fully stabilized   (typically 1-5 minutes). Please be patient. If still not working, add Apera 3M KCL (AI1107) to your pure water at the ratio of 1:1000 (e.g. 1 ml KCL to 1000 ml water) to accelerate stabilization while minimizing pH change. If the accuracy is not meeting your requirement, please contact us at [email protected] to find the specialized meter designed for pure water pH test.

Follow the steps in 7.3 to 7.4 to complete the 2 nd point of calibration using the 12.88 mS standard solution.APERA Premium Series PC60 5-in-1 Tester User Manual  & troubleshooting 38 will appear next to APERA Premium Series PC60 5-in-1 Tester User Manual  & troubleshooting 39 , indicating a successful 2-point conductivity calibration.
  6. Conductivity Calibration Notes

    The tester can calibrate 84μS, 1413 μS/cm and 12.88 mS/cm conductivity calibration solution. User can conduct 1 to 3 points calibration. Refer to the table below. Usually calibrating the tester with 1413 μS/cm conductivity buffer solution alone shall meet the testing requirement.

For conductivity calibration solutions, we recommend that users replace new solutions after 5 times of use to keep the standard solution’s accuracy. Do NOT pour the used calibration solutions back into the solution bottles in case of contamination.

Conductivity Measurement

  1. Short pressAPERA Premium Series PC60 5-in-1 Tester User Manual  & troubleshooting 43 to turn on the tester. Rinse the probe in distilled water and dry it. Dip the probe into your sample solution, make a quick stir, and hold still. Record the reading after it is fully stabilized (APERA Premium Series PC60 5-in-1 Tester User Manual  & troubleshooting 44 comes up and stays). PressAPERA Premium Series PC60 5-in-1 Tester User Manual  & troubleshooting 45 to switch from conductivity to TDS, and Salinity.
  2. Unit Conversion
  •  1000 µS/cm = 1 mS/cm = 1 EC (In conductivity mode, the unit will automatically turn from µS to mS if the reading is greater than 1999 µS, meaning you will only see 2.XX mS instead of 2XXX µS)
  • 1000 ppm = 1 ppt (In TDS mode, the unit will automatically turn from ppm to ppt if the reading is greater than 999 ppm, meaning you will only see 1.XX ppt instead of 1XXX ppm)
  • The TDS and Salinity values are converted from the conductivity values via a certain conversion factor. TDS and conductivity is linear related, and its conversion factor is 0.40 to 1.00. Adjust the factor in parameter setting P5 based on the requirements in different industries. The factory default setting is 0.71.
  • Salinity and conductivity is linear related, and its conversion factor is 0.5.
  • The tester only needs to be calibrated in Conductivity mode.
  • Conversion Example: if conductivity measurement is 1000µS/cm, then the default TDS measurement will be 710 ppm (under the default 0.71 conversion factor), and the salinity be 0.5 ppt. If TDS conversion rate is changed to 0.5, then the TDS measurement will be 500 ppm.

3. Temperature compensation factor

The default setting of the temp. compensation factor is 2.0%/˚C. User can adjust the factor based on test solution and experimental data in parameter setting P4. The following table is some common examples for setting up the temp. compensation factor.

Probe Cleaning

  1. The tester is only as accurate as the probe is clean. Always thoroughly rinse off the probe before and after each measurement with pure water in a container or with a wash bottle.
  2. For tough contaminants, detach the sensor shield, soak the probe in Apera probe cleaning solution (AI1166) or detergent water for 30 minutes. Then use a soft brush to remove the contaminants. Afterwards, soak the probe in 3M KCL soaking solution for at least 1 hour. Rinse it off, then re-calibrate the tester before using again

Probe Storage

  1. Under regular usage (daily or weekly use), make sure the probe cap is wet, and tightly close the cap with the O-ring.
  2. For long-term storage (you are not going to use the product for a while), add 3M KCL soaking solution to the Fill line in the probe cap and store the probe in it. Close on the probe cap tightly with the O-ring.
  3. If you find white crystals inside or outside the probe cap, it is perfectly normal. It is the 3M KCL soaking solution that crystalizes over time by its nature. Just rinse them off and add in new soaking solution. This chemical is not poisonous nor dangerous, and the probe’s performance will not be affected at all.
  4. NEVER store the probe in pure water like tap, RO, distilled, or deionized water as they could damage the pH probe. If this happens, immediately soak the pH probe Apera 3M KCL soaking solution overnight, then re-calibrate it before using. Pure water is only for rinsing the probe.
