3.OPERATIONS

1. Submerge the tipor the entire electrode into electrolyte.

Note: Readingsshould be taken as close to the structure as possible to minimize I.R.drop. Avoid surface contaminates.
 
 

4.MAINTENANCE & STORAGE

Before Use:

1. The Ag/CI elementmust be cleaned in distilled water or mild detergent and rinsed in 
   distilled water prior to use. 

2. Do not touch Ag/CIelement after cleaning. 

3. The Ag/CI elementshould soak in electrolyte for at least 15 minutes before use to stabilize
    readings.
 

After Use:

1. To ensure properreadings we recommend the Ag/CI element and the ceramic tip 
    assembly be kept moist during storage. A solid body tube and end plug areincluded for 
    this period as well as for use in soil readings.
