4.8.3.4  ISE Electrodes 
The steps of installing the ISE Electrodes are as follows. 
1  Take out  the reference electrode from the  package and  pull out the  yellow 
intubatton. Pull down the press plate of the ISE module and push the reference 
electrode into the ISE module. (Don’t throw away the yellow intubatton and 
use it again when storing the electrode.) If white crystalloids adhere to the tube 
of the reference electrode, wash it with warm water before installing.

Put the other electrodes into the ISE module. It is easier to install the K+, Na+, 
Cl- electrodes than the spacer electrode. To insert the spacer electrode (the 
top one), it is needed to slightly press the press board. 
 
Caution: Replace the space electrode with the Li+ electrode when necessary.
