• Long Press: > 2 seconds

BATTERY INSTALLATION

Please install batteries according to the following steps. *Please note the correct direction of battery installation:
The Positive Side (“+”) OF EVERY SINGLE Battery MUST FACE UP. (WRONG INSTALLATION OF BATTERIES WILL CAUSE DAMAGE TO THE TESTER& BATTERY LEAK !)

PREPARATION BEFORE USE

1. Pull out the battery insulation slip, and take off the probe cap.
2. Rinse off the probe in pure water (preferably distilled or deionized water. RO water or tap water is the alternative) , then shake off excess water (see graph on the right).
3. Perform at least a 2-point calibration. For pH calibration tutorial, refer to Section 6.
4. When you are not using the tester, always store the spear probe in the 3M KCL soaking solution. Never let it dry out. Replace the soaking solution if it gets contaminated.

pH CALIBRATION

1. Short press to power on the meter; rinse the probe in pure water. Shake off excess water.
2. Pour pH 7.00 and pH 4.00 buffer solution in the corresponding calibration vials (to about half volume of the vials).
3. Long press to enter calibration mode (screen turns green);- 6 –
4. Insert the probe into pH 7.00 buffer solution, make a quick stir, and hold still. When the reading is stabilized ( stays on screen), short press to start 1st point calibration. After calibration is completed, the tester will return to measurement mode. Icon will appear at the bottom left of the screen, indicating a successful 1st point pH calibration.
5. To calibrate 2nd point, use 4.00 pH buffer and repeat Step 6.3 to 6.4 (Do NOT turn off the tester after you finish pH 7 calibration). will display next to , indicating a successful 2-point pH calibration (low and middle points).
6. If necessary (target pH>8.00), calibrate 3rd point using 10.01 standard pH buffer and repeat Step 6.3 to 6.4, will show up next to and , indicating a successful 3-point calibration (high, low, and middle points).
7. Notes about Calibration
8. 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.
9. 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.
10. 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:
11. For the self-diagnosis information, please refer to the table below:

PH MEASUREMENT

1. PH60S-Z Spear pH tester is designed for direct spear test of solid samplings such as cheese, fruit, sushi rice, meat, dough. It also works well in general water solutions.

2. When performing spear tests in solid samples, pay attention to insert probe evenly, and be careful to prevent probe from damage. If the medium is too hard, please bore a small hole with a clean knife before inserting the spear probe.

   • For food pH measurement (e.g. sushi, cheese, meat, fruit, etc.), it should always be a sampling test. That means test samples should no longer be edible.

3. How to take pH measurements
   Short press to power on the tester. Rinse the probe in pure water, shake off excess water. Insert the probe in your sample solution or solid sample, and hold still. Record the reading when it is stabilized( stays on screen).

4. 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 info@aperainst.com to find the specialized meter designed for pure water pH test.

ORP MEASUREMENT

1. ORP stands for Oxidation-Reduction Potential, measured in mV. It’s also called redox. ORP is a measure of the cleanliness of water & its ability to break down contaminants. A separate ORP probe (ORP60-DA) needs to be installed to be able to measure ORP.
2. Power on the PC60-Z tester, unscrew the original probe, and install the ORP60-DA probe, then the tester will automatically switch to ORP measurement mode (Refer to Section 14 for how to replace a probe).
3. Rinse the probe in pure water and shake off excess water. Dip the probe in sample solution, make a quick stir and hold still. Record the ORP reading after it’s fully stabilized stays on screen.

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. Always store the spear probe in the 3M KCL soaking solution when not in use. Never let it dry out. Replace the soaking solution if it gets contaminated.
2. 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.

PROBE REPLACEMENT

pH probes don’t last forever. Every probe will eventually age and fail even if you don’t use it that often. The typical service life of Apera probes is 12-24 months depending on the frequency of usage and how well you keep it clean and properly stored. We recommend replacing your probe every 1 to 2 years to ensure the best performance.

To replace the probe: 1) take off the probe cap; 2) screw off the probe ring 3) unplug the probe; 4) plug in the new replacement probe (pay attention to the probe’s position); 5) screw on the probe ring tightly. Soak the probe in 3M KCL for 5-15 minutes. Then perform calibration before testing.

The replacement probes that are compatible with PH60S-Z:

• PH60S-DE (Spear pH probe for solids/semi-solids pH testing), PH60-DE (Regular pH glass bulb probe), PH60F-DE (Flat pH probe for surface pH testing), ORP60-DA (ORP Probe).
