[time-nuts] Oscilloquartz 3210 Cesium Standard

I recently bought an Oscilloquartz 3210 cesium standard and although it does
power up, it does not lock. All the parameters on the meter look 
sensible, other
than the 2nd harmonic, #9 parameter, which shows zero. Quart oscillator 
looks almost spot on in comparison with the lab Z3816. I have no info on 
unit at all, so this may either be a dead tube, or other electronic fault on
one of the many pcb's in the system. Ion pump had a small reading on 
power up,
but now dropped back to zero.

I am looking for a user guide for this unit, or even better, a manual 
with theory
of operation and setup info. Can anyone help with this, or perhaps suggest a
source ?. Year of manufacture estimated 1984/85, from date code on ic's.

I notice that the tube is from FTS, the same construction as in the FTS 
4060, but
different part number and wonder if this was original fitment, or has been
replaced at some stage...

Regards & Thanks
