PH Meter calibration
1.immerse the electode in PH 6.86(under the temperature of 25centigrade)
standard buffer solution of phosphate, and gently shake the electrode.
2.Regulate the trimmer with a screwdriver until the buffer solution value
corresponding to the measurement temperature is obtained.
3.Immerse the electrode in PH 4.01 or PH 9.18 the standard buffer solution of borax.
4.After about one minute,until the buffer solution value corresponding to the
measurement temperature is obtained.
OPERATION :
1.remove the protective cap.
2.First clean the electrode with distilled water,and suck it with filter paper.
3.Turn on PH by "NO-OFF"switch located on the top of battery case.
4.Immerse the PH meter electrode in solution up to the immersion level.under
no circumstances immerse above display level.
5.Stir gently and wait for the reading to stabilize.
6.After use,switch off it,use the distilled water clean the electrode
and replace the protective cap.
