Immerse pH electrode into 

buffer solution, 

for example, pH 7

1.  Plug in the pH monitor to turn on. The monitor will 

be in pH measurement mode.  

2.  Rinse the probe thoroughly with de-ionized water or 

a rinse solution. Do not wipe the probe; this causes 
a build-up of electro-static charge on the glass 
surface.  

3.  Dip the probe into the calibration buffer pH 7. The 

end of the probe must be completely immersed into 
the sample. Stir the probe gently to create a 
homogeneous sample.  

4.  Press the CAL key to enter the calibration mode. 

"CA" will flash on the display for a second and then 
a value close to pH 7.0 will flash.  

5.  Let the electrode soak in the buffer until reading is 

stable, stirring occasionally (time will vary 
depending on temperature and electrode 
condition). When the display has flashed the same 
pH value for 15 seconds or more, press the ENTER 
key. "CO" will flash on the display.  The reading 
should now display pH 7.0.  See Figure 2.  

If necessary, repeat steps 2 through 5 for the 
remainder of the buffer values (pH 4.0 and 10.0).
