Things to Know Before Use

5.1 Generally, users can start using the tester directly. If the measuring response is slow, users can soak the ORP 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 ORP electrode responds slowly, You can soak the ORP electrode for 8 hours in the storage solution before using.
5.2 When the tester is not in use, keep the ORP electrode in storage solution.
5.3 Do not soak the ORP electrode in purified (e.g. distilled/deionized) water for a long time, which will make the electrode response slow. If this happens, soak the ORP electrode in 3M KCl solution for 3~5 hours, and then re-calibrate it before using.
5.4 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.
5.5 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

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. 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.

ORP Calibration

7.1 Pour some 222 mV ORP standard solution into the calibration bottle (to about half volume).
7.2 Rinse electrode in distilled water and dry it. Short press to turn the meter on. Long press to enter calibration mode. If you need to exit calibration mode, short press .
7.3 Dip electrode in the standard solution, stir gently, and allow it to stand still in the calibration solution until a stable reading is reached. When stable icon comes up and stays, press to adjust the calibration value according to the table below (also on thesolution bottle’s label). Then short press to complete the calibration.

222 mV (25˚C) ORP Standard Buffer Solution Calibration Reference Table

Temperature (˚C)| mV| Temperature (˚C)| mV
10| 242| 30| 215
15| 235| 35| 209
20| 227| 38| 205
25| 222| 40| 201

For example, if the temperature is around 25˚C, then adjust the calibration value to 222 mV. If the temperature is around 20˚C, then adjust the calibration value to 227 mV.
7.4 Notes
Usually there’s no need to calibrate for ORP testing. When the tester has been used for a long time, users can test it in 222 mV ORP standard buffer. If the error is big, please calibrate according to the steps in 7.1 to 7.3.
The meter has self-diagnosis function. Please refer to the followed chart for detailed information.

Wait till the smile icon appears and stays, then short press
| During calibration, readings being unstable for over 3 minutes| 1. Please check whether ORP electrode is damaged or broken. If so, please replace with a new one.
2. The platinum pin or junction is severely contaminated. Please use a soft brush with soap water to clean it thoroughly. Then soak it in 3M KCL overnight before performing calibration again.
3. The electrode is aged (used for over a year and has a much slower response). A replacement is needed.

7.5 The Maintenance of ORP Probes
After long-time use, the surface of the platinum pin can be contaminated and cause inaccuracy or slow response time. If that happened, the following methods can be adopted to clean and reactivate the sensor:
a) For contamination caused by inorganic substances, dip the probe into 0.1 mol/L dilute hydrochloric acid for 30 minutes. Clean it with distilled water, soak it into the KCL storage solution for 6 hours, and then it will be ready for use again.
b) For contamination caused by organic substances and oiliness, clean the platinum surface with dishwashing liquid, and rinse with distilled water. And then the probe will be ready for use again after 6 hours’ soaking in the storage solution.
c) If the platinum surface is so severely contaminated that there forms an oxide film, toothpaste can be used to clean the platinum surface, and then wash it with distilled water. The probe will be ready for use again after 6 hours’ soaking in the storage solution.

P4| Automatic Power Off| 10-20 minutes – Off| 10
P5| ORP restores back to factory default| On — Off| Off

8.2 Parameter Setting

1. When the meter is turned off, long press to enter parameter setting →short press to switch P01-P02… →P5. Short Press , parameter flashes → short press to adjust parameter → short press to confirm →Short press to exit parameter setting and go back to measurement mode.
2. Auto. Lock (P02) – Users can set the auto lock time from 5 to 20 seconds. For example, if 10 seconds is set, when the measured value is stable for more than 10 seconds, the measured value will be automatically locked, and the HOLD icon will be displayed. 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. ORP Back to Factory Default (P05) – Select “Yes” to restore 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.
