The meter might be correct and the transmitter may not. I'd check it on other meters FIRST as it might be fine.
....Just wondering though, what would you use to ACCURATELY calibrate it??
I have 2 BIRD 43s and a 4304A.
2xBIRD 43s & 1-4304A.JPG
All give me a reading of +/- 400W into a 600W BIRD Dummy load
when the Elenos says 460W
So my guess is the Elenos is off

if you know the exact efficiency of the amplifier, you can know the output power through the calculation of the amplifier's voltage and consumption...
Can you mesure as is on photo as exsample

- Update
Received a 24064B Display from Aliexpress @
€22 inc post 
24064B Display.JPG
It's a 22pin which means the Led Backlight is connected differently
So modifications required to isolate it from the Display Circuit

It's still working fine, it's under the bench.
However...
It's not as efficient as the 500W at lower power

How much power are you running day to day?
