PD6620 Series 

Loop Leader

 

Loop-Powered Rate/Totalizers

Free, PC-based, MeterView XL software that connects to the meter 

via a micro USB cable is available for programming and setup of the 

meters. This software greatly simplifies the programming process 

and also allows the user to save configuration files for later use. The 

meter will also be powered by the USB connection so no additional 

power is needed during programming.

▲  

The main screen displays an image of the connected meter and 

includes various information about this meter, such as model 

number, readings, and status.

▲  

The Input/Scale window is used to: 

▲  

The 4-20 mA Output window is used to program the isolated 

4-20 mA output’s source, range, and under and over range values.
