It can break if being contacted by external force. If broken, the probe needs to be replaced. 2) Things needed in addition to what's in the box: a) Distilled or deionized water (8-16oz) for rinsing the probe after each test b) Tissue paper for drying the probe 3) For PH60-Z and PH60F-Z testers: a) A few drops of water are added to the probe cap to keep the pH electrode in an activated state before the tester leaves factory. Generally, users can start using the tester directly. If the measuring response is slow, users can soak the pH electrode for 30 minutes in the 3M KCL storage solution (fill to the fill-line) before using it; if the electrode is dry for a long time (> 1 month), the pH electrode responds slowly, You can soak the pH electrode for 8 hours in the storage solution before using. b) When the tester is not in use, we recommend adding one to two drops of tap water to the probe cap, and close the cap (be careful not to add too much water). This way, the pH probe's sensitivity can be maintained and users can start using the tester right away next time. c) Do not soak the pH electrode in purified (e.g. distilled/deionized) water for a long time, which will make the electrode response slow. If this happens, soak the pH electrode in 3M KCl solution for 3~5 hours, and then re-calibrate it before using. d) The storage solution is 3M KCL (SKU: AI1107), and the tester kit comes with a bottle of 10mL storage solution (can be used repeatedly). If it is contaminated, replace it with a new one. Please do not use other brands' storage solutions as they may contain other chemicals that can cause damage to the electrodes. 4) For PH60S-Z Spear pH Tester: NEVER store the spear probe in a dry condition because permanent damage CAN be caused. The spear probe should always be stored in the 3M KCL soaking solution. - 5 - 6 pH Calibration 6.1 Calibration Steps 1) Short press to turn on the meter; rinse the probe in distilled water, shake the meter in the air and use tissue paper to dap off excess water (never rub or wipe the sensor tip). 2) Pour certain amount of pH 7.00 and pH 4.00 buffer solution into the corresponding calibration bottles (to about half volume of the bottle); 3) Long press to enter calibration mode; Short press to exit. 4) Place the probe in pH7.00 buffer solution, shake it for a few seconds, and allow it to stand still in the buffer solution until a stable reading is reached. When stable icon stays on the LCD screen, short press to complete 1st point calibration and the tester returns to measurement mode. Indication Icon will appear at the bottom left of the LCD screen. 5) Rinse the probe in distilled water and dry it. Long press to enter calibration mode to perform 2nd point of calibration. 6) Place the probe in pH 4.00 buffer solution, shake it for a few seconds, and allow it to stand still in the buffer solution. When stable icon stays on the LCD screen, short press to complete 2-point calibration and the tester returns to measurement mode. Indication icon will appear at the bottom left of the LCD screen. 7) If necessary, rinse the probe in distilled water and dry it, and place the probe in 10.01 buffer solution (sold separately) to complete 3rd point of calibration according to the steps in 6), will appear at the bottom left of the LCD. 6.2 Notes 1) Tester will automatically recognize pH buffer solution. Users can perform one-point, two-point, or three-point calibration. For the 1st point calibration, only 7.00 pH/6.86 pH solution can be used. Then use other buffer solutions to conduct 2nd or 3rd point calibration. Perform the 2nd point calibration (4.00 pH) immediately after the 1st point. Do NOT turn off the meter before you perform 2nd point calibration. If the meter is turned off after 1st point calibration, users will need to restart the calibration process with the 7.00 pH or 6.86 pH first and the 2nd point following after. Otherwise, Er1 will occur. 2) The tester will automatically recognize 5 kinds of pH buffer solutions in both USA and NIST series of standards. Refer to the table below: Calibration USA Series 1-point 2-point 3-point 1) 7.00 pH 1) 7.00 pH 2) 4.00 or 1.68 pH 1) 7.00 pH 2) 10.01 or 12.45 pH 1) 7.00 pH 2) 4.00 or 1.68 pH 3) 10.01 or 12.45 pH NIST Series 1) 6.86 pH 1) 6.86 pH, 2) 4.01 pH or 1.68 pH 1) 6.86 pH, 2) 9.18 pH or 12.45 pH 1) 6.86pH 2) 4.01 or 1.68pH, 3) 9.18 pH or 12.45 pH Calibration Indication Icon Recommended Accuracy and Range Accuracy 0.1 pH Measurement Range7.00 pH Measurement Range7.00pH Wide Measurement Range - 6 - 3) For pH Calibration buffer solutions, we recommend that users replace new buffer solution after 10 to 15 times of use to keep the standard buffer's accuracy. Do NOT pour the used calibration solutions back into the solution bottles in case of contamination. 4) When calibrating strong basic solutions (pH>10), use 7.00 pH and 12.45 pH to calibrate; When measuring strong acidic solutions (pH<4), 7.00 pH and 1.68 pH should be calibrated. 5) For the self-diagnosis information, please refer to the table below: Symbol Self-Diagnosis information Potential problems and how to fix The pH calibration solution cannot be recognized by the meter. 1. Make sure the probe is fully immersed in the calibration solution. 2. Check if calibration solution is expired or polluted. 3. 1st point of pH calibration must be pH 7.00 or 6.86. See 6.2 (1). 4. Please check whether pH electrode is damaged or broken. If so, please replace with a new one. 5. The glass bulb or junction is severely contaminated.

Rinse the probe in distilled water and dry it. Dip the probe in sample solution, stir gently, and allow it to stand still in the solution. Get readings after comes up and stays on screen. Notes For solutions with low ionic strength (e.g. distilled or deionized water), the pH measurements will be fluctuating and difficult to get a stable reading. A specialized pure water pH electrode is required. For more information, please contact us at info@aperainst.de. Likewise, when testing clean water such as drinking water, RO water or tap water, the test time could be longer, usually 24 minutes. 7.1 Applications of different models Model/Probe Application PH60-Z glass bulb General water solutions' pH measurement such as hydroponics, sensor aquaculture, pools and spas, water treatment, beverage, etc. PH60S-Z Spear tip Solid samples such as cheese, meat, fruit, vegetables, sushi rice, sensor bread, and soil; also works well for general water solution. PH60F-Z Flat glass membrane Flat surface measurement such as skin, paper, fabric, leather and so on; micro sample testing; also works well for general water solution. 1) PH60S-Z Spear pH testers are widely used for solids containing water or semi-solid medium. When performing such tests, pay attention to insert probe evenly, and be careful to prevent probe from damage. If the medium is too hard (such as meat or fruits), please bore a small hole with a knife before inserting the 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. 2) For soil direct pH test with PH60S-Z a) If soil is dry, add small amount of distilled or RO water to moisten the soil (do NOT add tap water since it will affect the pH value significantly). Ideally wait 24 hours before you take a measurement. b) Rinse the probe with distilled water/RO water before inserting it to the soil. c) If measuring outside of solution, rockwool or small pots, remove the top 5cm/2inch soil from the surface of the sample area. Insert the spear probe approximately 4 to 6 inches (10 to 15cm) into the soil samples from various locations (3 to 4), wait for the stable readings before recording (smiley face icon stays on the screen). d) Users can save all the data in ZenTest App. Then take the average of the saved data as the representative pH level of the soil. e) Do NOT use extra force to insert probe. If you feel like the probe can't be inserted any deeper, stop inserting. The spear tip could break. f) Rinse off the soil residue between tests using distilled water or RO water for the best results. Use the probe cleaning brush if needed. - 8 - 3) PH60F-Z Flat probe testers are mostly for flat surface sample test. a) For skin test: skin should be without sweat or dirt, nor be overly cleaned (do not use facewash products before testing) to avoid affecting measurement results, dampen skin with some distilled water, slightly force flat probe onto the skin, get readings after value stabilized. b) For paper, fabric and leather test: add a few drops of distilled/deionized water on surface before performing tests. c) For micro sample testing, use a container with an inner diameter<=19mm and a flat bottom. The tester can test volume >=0.5ml. 8 ORP Measurement 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. Power on the PH60-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). Rinse the probe in distilled water and dry it. Dip the probe in sample solution, shake for a few seconds, and allow it to stand still. Get the ORP readings after appears and stays on screen. 9 Parameter Setting 9.1 Table of Settings Symbol Parameter Setting Contents Content Factory Default P1 Temperature Unit °C °F °F P2 Select automatic lock 5-20 seconds Off Off P3 Automatic Backlight Off 1-8 minutes Off 1 P4 Automatic Power Off 10-20 minutes Off 10 P5 pH Buffer Series Selection USA NIST USA P6 pH Resolution 0.1 0.01 0.01 H-hours D-Days (set up in P7 pH Calibration Reminder / ZenTest App) P8 pH back to factory default No Yes No 9.2 Parameter Setting 1) When the meter is turned off, long press to enter parameter setting short press to switch P01-P02...

Short press to release the lock. When the setting is "Off" , the Auto. lock function is turned off, that is, the measured value can only be manually locked. Short press to lock or unlock the measured value. The HOLD icon will be displayed when reading is locked. 3) Auto. Backlight (P03) Users can set the automatic backlight time for 1 to 8 minutes. For example, if 3 minutes is set, the backlight will turn off automatically after 3 minutes; when the "Off" is set, the auto. backlight function will be turned off, and short press to manually turn the backlight on or off. 4) Auto. Power off (P04) The auto. power off time can be set to 10 to 20 minutes. For example, if 15 minutes is set, the meter will automatically shut down after 15 minutes if no operation; when "Off" is set, the auto. power off function will be turned off. Long press to manually shut down the meter. 5) pH Calibration Reminder (P07) set X hours (H) Or X days (D) in ZenTest mobile app settings Parameter pH Calibration Reminder. On the meter, you can only check the values that's been set up on ZenTest App. For example, if 3 days is set up, the Er6 icon (see Figure-4) will appear in the lower right corner of the LCD screen in 3 days to remind you to perform calibration, also in the ZenTest App there will be a pop-up reminder. After calibration is finished or the reminder setting is cancelled in the ZenTest App, the Er6 icon will disappear. 6) pH Back to Factory Default (P08) Select "Yes" to recover instrument calibration to theoretical value. This function can be used when instrument does not work well in calibration or measurement. Calibrate and measure again after setting the instrument back to factory default. 10 Technical Specifications pH ORP (mV) Temperature Range Resolution Accuracy Calibration Points Auto.
