1 phase meter assining to correct phase

[bilbolodz]

I've a two (actually more than two) Easton meters:
SDM630 (3 phase)
SDM230 (1 phase)
Now SDM230 shows measurements as "on phase 1" (it's obvious it has only 1 phase).... BUT it's connected to phase L3 so SDM630 and SDM230 shows on "L1" different values (e.x. voltage etc). It's could be a good idea to "tell" 1 phase meters to which phase are connected and artificially "move" data from L1 to Lx
