Programming Software 
(Free download at omega.com)
Allows configuration of the LDPF63100 
meter from a PC. This software offers 
standard drop-down menu commands, 
that make it easy to program the meter. 
The unit program can then be saved in a 
PC file for future use. A serial plug-in 
card is required to program the meter 
using the software.
