[Milsurplus] TV-2 tube tester question

[HL1FB]

Hello
I recently acquired a military TV-2C/U tube tester and I am in the process of
repairing it. I found the PERCENT QUALITY meter is not functioning.
I want to know the specification of the PERCENT QUALITY meter.
Mine looks open circuited and I need to know what the internal resistance is
to rebuild it. On the face plate of the meter it is written 100uA full scale but
I believe it is 100uA at point 100 anf 150uA at full deflection(full scale at point 150).
If someone has a good TV-2, could you please measure it and let me know?
All Tv-2/U, TV-2A/U, TV-2B/U and TV-2C/U should use the same meter.
TV-2 manual does not specifify the meter resistance.
This meter is different from TV-7 meter.
Thanks in advance.
