By using multiple RDE300i units you can perform applications such as soiling or bifacial gain measurement where a test module is compared to a reference module. 


Connect the reference module (such as the clean reference for soiling applications) on one RDE300i to be designated as the Leader unit and place the test module (such as the dirty module for soiling measurement) on another RDE300i to be designated as a Follower unit.


To configure and normalize your RDE300i units for these applications, follow instruction guide 880096-01, "Configuration and Normalization Guide for Multi-RDE300i Systems," available via the link at the bottom of this page.
