    Default Taylor-Hobson Talyvel 4

    I've just purchased a old Taylor-Hobson Talyvel 4. The seller described this as "ancient, but in good working order".

    For those who are not familiar, this is a precision differential electronic level with two read heads (A and B). It has an LCD digital display with a resolution of 0.1 arcsec and a range of +-600 seconds, and a claimed accuracy of 0.2 arcsec near zero. It can display A, B or A-B, which is nice because by parking head B at a fixed position and moving only head A, you can compensate for any shift or tilt in the machine.

    The level won't be delivered for another week, but meanwhile I am gathering information. Taylor-Hobson sent me an instruction manual by email, which includes the procedure for balancing the bridge circuits in each head and for setting the gain correctly.

    Does anyone here own a Talyvel 4? I'll post some photos and a report after I have received it.
