7236 tube testing problem, seeking advise

TESTER-TV10D/U
While testing some tubes today I ran into a problem testing a couple 7236 tubes (Cetron, Sylvania). I had the tester set for 6AS7 thinking this was the class of the 7236. Both tube read out at 200-300 on the GM meter, unlike the 5000-5800 for other tubes marked 6AS7G (Min 1800).
Not wanting to damage the tubes stopped seeking clarafaction of the tube class or settings.
Any advice is appreciated.
Thanks
Wil
