By the operating manual of the tester the minimum value
of the MC (Mutual Conductance) of the NEW ECC83 (12AX7) vacuum tube is : 875
This is taken as 100%.
(Given for each tube System 1 and System 2 [in Micromhos]).
On each tube I placed a little white sticker with the measurement results.

MUTUAL CONDUCTANCE TEST: here we can get exact
numerical value in Micromhos.
The condition of TUT (Tube Under Test) can be expressed in percent.
For example : in case of the NEW ECC83 (12AX7) listed minimum
value of mutual conductance is 875 Micromhos.
If the TUT has 1.500, the percental condition is
(1.500/875) x 100% = 171 %.

Result of the mutual conductance test, as follows :
