Please follow up below procedures when you want to use or store the probe. Step1 Rotate the bottle to remove the bottle away from the probe. Step2 Push down the cover and remove it away f.rom the probe. After using, please put back the cover on to probe, plug the probe into bottle and then rotate the bottle to make the bottle sealed well with cover. 3 AUTO POWER OFF (SLEEP FUNCTION) This instrument will shut off automatically in approx. 20 minutes for every power on. For recording or operating over longer periods of time, you can disable the sleep mode by pressing I and CAL simultaneously before power on. An "n" will appear in the middle of the screen at which time you can release the CAL button. (See Fig. A) The disable sleep mode will be invalid after power off. Fig. A Fig. B MODE OPTIONS Delete and replace with programmable user selectable start- up mode. The display will CAL pH/mV default to the mode last used. For your OC/ FO convenience, the meter defaults to the + CAL = Disable Sleep Mode pH/mV = = REC = Save Cal. OC/FO = Escape/Cal.4.00 7.00 10.00 setting used during the last operation. The following table lists the modes of operation that can be invoked by pressing the button indicated. I Turns instrument on (Default setting) and off. (See Fig. B) REC Press momentarily and relative clock starts in the lower right screen. 4 When in REC mode, (REC displays in the middle left of the LCD, Fig. C) pH/mV and CAL function keys are locked out. In REC mode, press REC key to display MAX (Fig. D) and MIN (Fig. E) and back to current pH in cycle. Press and hold REC for 3 sec. to turn off the record function and revert to the normal mode. CAL Press momentarily to enter the Calibration mode. (Fig. F) Fig. C Fig. D Fig. E Fig. F pH/mV Press momentarily to toggle display data from pH to mV or from mV to pH(Fig. G). Or press momentarily to increase the figure when calibration is performed. OC/ FO Press momentarily and the unit toggles between oC and oF temperature(Fig. H); The unit mode is indicated on the middle bottom area. Or press momentarily to escape current calibration to the next point. Fig. G Fig. H 5 Press momentarily and the backlight illuminates for approx. 30 seconds then turns off automatically. Or press momentarily to decrease the figure when calibration is performed. AUTOMATIC TEMPERATURE COMPENSATION (ATC) The meter is recommended to use AZ86P3 three in one epoxy combination probe with a temperature sensor probe for the automatic temperature compensation (ATC), the meter is capable of taking measurements with automatic or manual temperature compensation. Ensure the AZ86P3 probe is plugged into the meter for ATC, otherwise use AZ86P2 Two in one probe and additional temperature probe, the probe must be submersed in the liquid you are measuring. CALIBRATION Calibration is necessary and should be done regularly. 1. Power on the meter. 2. Press CAL button to enter pH calibration mode, you will first see " 4.00 pH" on the LCD readout. If the buffer is incorrectly inserted or the probe is damaged, "Err" will appear on the bottom-right corner. (Fig. I) Fig. I 6 3. Press pH/mV button to increase(Fig. J) Or press to decrease (Fig.K) the displayed value in order to meet your calibration buffer. The adjustable range for 4. 00 pH calibration point figures from 3.50 to 4.50. (Fig. J, K) Fig. J Fig. K 4. Ensure the measured pH value to stabilize in the bottom-right corner, it means the meter is now calibrated to the current buffer, the 4.0pH calibration point is now completed. (Remark: The value shows beside CAL is a reference value of mV ). The correct mV value is the digits you see from the right bottom corner but with a decimal point after 3rd digit ,i.e. before 4th digit . For example , if you see 1234 after CA , the mV value should be 123.4 . 5. Press REC to save the calibration, " SA" will appear on the LCD(Fig. L). Fig. L If you are performing multipoint calibration, press OC/ FO to go to the next pH 7.0 calibration procedure. 6. Rinse the probe with de-ionized water or a rinse solution, and place it in the next pH buffer. Follow the procedures as pH 4.0 for additional pH 7.0 calibration, the range for 7.0 pH calibration point figures from 6.50 to 7.50. 7 When calibration is complete, save the calibration by pressing REC , otherwise, escape by pressing OC/ FO to additional calibration (pH 10). (Fig. M) Fig. M Fig. N 7. Follow the same procedure as pH 4.0 and pH 7.0 for pH 10 calibration point. The range for pH 10.0 calibration point figures from 9.50 to 10.50.(Fig. N) 8. After saving the calibration of the last pH 10.0 point by pressing button, you will see an "END" appears on the LCD, it means the calibration has been completely finished. (Fig. O) Fig. O NOTE: The meter can be manually set up the temperature value for ensuring an accurate pH measurement. This function is used when your pH electrode is ATC feature exclusive. Please follow up below steps. a)Press CAL button to start 4.00pH calibration point, for setting up the temperature value, press and hold OC/ FO button 2 seconds , "St" will display above the default 25oC.(See Fig.I-1) To increase the temperature value by press pH/mV button , or press button to decrease the temperature value. 8 The temperature range is -5oC~80oC, press REC button to save the temperature value. b)Easy to measure the pH value with 2 in one electrode (86P2AZ), or any compatible pH electrode without temperature compensation, now you will see the temperature setting value replaced pre-set temperature. Fig I-1 MAINTENANCE Please always keep the pH glass bulb wet by using the plastic bottle to protect and store our electrode, you can also store in a pH 4.0 buffer with 1/100 part of saturated KCL. Never use distilled water for storage. Always rinse the pH electrode and reference junction in de-ionized water before next use. Never touch or rub glass bulb for lasting pH electrode life. This meter is designed with cloth junction. To prolong the life of the electrodes, it is recommended to clean them monthly by immersing them in cleaning solution for half an hour. Afterwards, rinse it with tap water and re-calibrate the meter. The other way to prolong the life of the electrodes is to extend the cloth junction and cut the dirt portion. 9 The extendable cloth reference junction is used to eliminate the reading errors from clogged junction. Follow up below steps to expose the new unused portions. Extendable cloth junction Step1 Using tweezers to pull out the cloth junction and expose the new unused portion. Step2 Cut the clogged cloth and expose the new portion. TROUBLESHOOTING ? Power on but no display. Check the battery are in place and making good contact or correct polarity , replace a new battery or attach optional AC adaptor for the weak battery caused. 10 ? Unstable reading. Clean the probe and recalibrate or make sure sample entirely covers the probe sensor, or replace a new probe and re-calibrate if you find a broken probe. ? Slow response. Clean probe by immersing the electrode in tap water for 10-15 minutes, then thoroughly rinse with distilled water or use a general purpose electrode cleaner. You could also follow up the maintenance steps of cloth junction renew in page 10 to improve the response time. ? CAL: Err. Calibration error. Replacing wrong buffer with correct one or input a correct buffer value. If above are not working, the probe might be damaged or broken, replace a new one and re-calibrate. ? BAT indication. Replace with a new battery. (Fig. P) ? E.1. Out of pH range, too acid (<0pH). (Fig. Q) ? E.2. Out of pH range , too alkali (>14 pH). Plug in the pH electrode and temperature sensor probe (if any).
