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

be in ORP 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 surface.  

3.  Dip the probe into the calibration standard. The end 

of the probe must be completely immersed into the 
sample. Let probe soak 2 to 5 minutes or until 
readings stabilizes.  

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 the calibration standard will flash.  

5. Press the 

S or T keys to adjust the display to 

match the calibration standard value. Press the 
ENTER key. "CO" will flash on the display. The 
reading should now display the same value as the 
calibration standard. See Figure 3.
