Follow these steps immediately if the unit is immersed in any 
solution: 
 
1.  Rinse unit carefully with distilled water. After rinsing and drying, 

inspect and clean connectors to remove all contaminants that 
may affect probe connections. 

 
2.  Wait for the unit and probe to dry completely before resuming 

operation. 

 
3.  If the unit does not function correctly after steps1 and 2, call 

JENCO for possible repair or replacement (see Warranty). 

 

INSTALLING THE BATTERIES 

 

 

The pH6810 meter is packaged with 4 “AAA” alkaline batteries 
required for operation. To insert the batteries into the meter, follow 
the procedure outlined below.

   

 

1.  Use a screw driver to remove the two screw and battery cover to 

expose the battery compartment. (Figure 1.)

             

 

 
2.  Note the polarity and insert the batteries into the battery 

compartment correctly. 

 
3.  Replace the battery cover and make sure to secure the two 

screws for the water-tight feature. 

 

[

Note: 

Press the “On/Off” key to turn the unit on. If the unit is 

running then you can press the ”On/Off “ key to turn the unit off. 
The unit will automatically turn off after 20 minutes of no key 
activity.]
