Set Up 

 

 

 
 
The following section provides a step by step guide to the 

operating instructions for the corrosion rate meter. 

 

 

 

 

 

 

 
 

 

 

 

 
 
 

 

 

 

 
 

 

 

The above diagram provides the connections required to 

carry out the corrosion rate measurement.  Note that either 
two connections are provided to the reinforcement or a 
single connection is acceptable if less than 10metres.  In this 

application a link is required to interconnect the WE and SE 

terminals on the meter.
