String example 2: Element Description
Change the Element Description from “Mains Bld 100” to “Mains Bld 101”
It may be tempting to update only the character number “0” to “1” in the description, but this will NOT
perform as expected. Internally, the meter uses a single string buffer for all string register blocks and
unspecified entrees will continue to contain the previous buffer contents unless specifically written to.
