Testing a CZ30 tube on a Jackson 648 tube tester

Hi,
Would anyone know the settings for testing a GZ30 tube on a Jackson 648
tube tester?, I found a nice Mullard and want to test it.

CZ 30 means GZ30 ?

Like a 5Z4

Same as 5Ц4C (cirillic of 5C4S) and 5Z4P

Are you sure it's not a GZ30?

Yes my mistake, I corrected it, thank you

if you've got 5Z4 test settings, that should do it.

Failing that, try 5V4 settings maybe?
