Sometimes you will want to know how you sensor is 
functioning. To view the sensors zero mV output 
from the electrode (AS), Slope (SL) and 

Impedance 1 and Impedance 2. From the Main 
screen press the I icon in the circle. 
 
 

 
 
 
 
 

The following screen will pop up press the 
diamond next to NEXT.  
 
 

 
 
 
 
 

 
 
 

Then… the data screen will appear. The zero is 
the AS, the slope is the SL, and the impedance 

2 is the impedance of the reference junction. 
The sensor mV reading is a continuous reading 
of what the sensor is seeing in normal 
measureing mode  
 

 
 
To return to normal measureing mode press the 
house icon.
