2.  Installation 

2.1  Install the stand-alone electrode holder 

1.  Attach the magnetic part on the bottom of the meter to the magnetic part on the 

stand-alone electrode holder to finish installation. (Both marked in red 

demonstrated below.) 

 

 

2.  The two tension knobs can be adjusted by turning clockwise to tighten or turning 

counterclockwise to loosen. When they are loosened, you can move the holder up 

and down, forward and backward to the desired angle. Then you can tighten the 

knobs to fix the holder.
