approx. 150 hours of use
1.Take off the protective cover.
2.And clean the electrode (electrode cover around the white crystalline salt, which is a normal phenomenon, as long as the pH electrode can be dissolved in water. The electrode is located and disappeared)
3.Switch battery compartment, pH will be inserted into the measured liquid, until the liquid dipped slightly bottom line. The immersion conditions allow, can make solution to the location of the line is slightly higher than that of immersion
4.Stir gently until the display is stable and the display value is read.
5.After use, clean the electrode with clean water to reduce the pollution.
6.A few drops of saturated KCL solution can be dripped into the protective sleeve to maintain the electrode
7.Turn off the switch and put the protective sleeve on it.
*Insert the electrode into the standard buffer solution of the pH value of 6.86 (25 C) mixed phosphate and stir gently, and the value is stable.
*Adjust the correction potentiometer with a small screwdriver until the display value corresponds to the pH value of the standard buffer solution at ambient temperature.
*The electrode is inserted into pH4.01's Potassium phthalate two formate or pH9.18 in the standard buffer solution of borax.
*The display value should be within the allowable range of error compared to the pH value of the buffer solution.
