Hello AMMRL Community,
Our MAS II unit seems to have significant issues with regulating the spin speed
(+/- 50 Hz, irrespective of probe) and always has an offset of about 30 Hz from
the target spinning speed. In manual mode operation, the spinning= speed has a
constant drift to higher frequencies and then suddenly drops to lower spinning
speeds by ~100 Hz. Has anyone experienced this? Further, if anyone has or knows
someone I could contact to obtain a MAS I or II spin speed controller that
would also be a significant help.
Thank you,
Derrick
