I believe that this is just a "software version number" that shows when the meter is turned on. It is in no way an error message or a fault with the meter. It momentarily displays on the LCD when you turn the meter on before it goes into the measurement mode. I hope that this helps.

When I attempt to calibrate in the 7.0 solution the meter reads 5.3 and doesn’t move up nor down.
