Hi:

I have a problem on our INOVA 400 which happened over the weekend.

I inserted Agilent Auto Test Sample and clicked Find z0 button from Start/Lock
page. I enabled Lock scan and got a flat lock scan if Lock box was unchecked,
but a sine wave when Lock box was checked. I tried to calibrate Gradient,
generate a new lk gradient map, and calibrate z0 with Auto Test Sample
but didn't help. Any idea what was wrong?

The system is INOVA 400 with AutoX probe ( We don't have broad band probe for
this system. Just use AutoX probe to run 1H and 13C related experiments).
OpenVnamrJ 2.1 Revision A is the NMR software which is installed on a centOS
Linux 7.9.2009.

Thanks,

Nelson
