DO Operation: 

Standardizing  

XL40 and 60 meters

 

The XL40 and XL60 meter has two standardization modes for % saturation and mg/L: automatic 
and manual. The factory setting is for a one point automatic standardization in % saturation. 
Refer to the setup section to choose measuring units, one or two point standardization, and 
automatic or manual standardization. There is no standardization for mbar measuring units. 

 

 

 

 

 

 

 

 

 

Note:

 Allow the probe to warm up for 30 minutes after connecting it to the meter and prior 

to standardization.
