Not really. It displays the mV value when you enter the calibration mode. If it's not within a defined range, calibration does not occure.
So to know the mV value at 6m, you'll have to switch off the rEvodream, switch it on, tap to enter calibration, write down the values.
With the Hammerhead, you have a menu to display the mV values of the 3 cells. And it can be activated underwater if I understood correctly the manual (didn't dive with mine yet).
Thanks for the clarification. While rEvo mV readings may not be as extensive as the HH, it still serves to help note mV trends of cells during calibration.
