question about the lavatube v2 voltage

[mattb56601]

Ok all here is a question to users of lavatubes v2. I have had two of these now and both seem to have the same issue, the voltage readout seems to not be correct. I set it to 3v on the display and check it with with a multimeter the reading that im getting is 1.3v at 4v on the display the meter reads 2.8v at 5v its reading 3.8v for a couple of seconds than jumps up to 4.8v and and at 6v its reading 6.1v so on the higher voltages it seems to get better. just to make sure of this I used a fresh battery and a second multimeter to double check and had the same results. So if anyone with a meter could please check there's and let me know if its just me or if it is a common problem with these units i would appreciate it. Thanks
