7.6 Transferring a File from a PC
The PM880 enables you to transfer site (.sit) and meter (.met) files from 
your PC to the meter. If you rename another type of file with one of these 
extensions and transfer it, it will be transferred, but will not function if you 
open it.
Note: The PM880 IR function is already setup for IrDA infrared 
communication. To change IR settings, Setting Up PM880 IR 
Communications on page 110.
The transfer procedure differs depending on your PC’s operating system. 
Use the appropriate section that follows to transfer files:
IMPORTANT: If you transfer a file and the meter already has a file with the 
identical name, the meter will overwrite its current file with 
the transferred file. If the transferred file has a name longer 
than eight characters, the meter will shorten the name to eight 
characters. It will also replace any spaces in the name with 
underbars.
