Thanks John,
 
If anyone fancies a visit here is the manuals page http://www.polarinstruments.com/manuals/manuals.html (found through Google that seems to circumvent their registration page) the ToneOhm 550A (3MB) file shows schematics if you're interested how these things 'tick'.
 
That's the Baby I used to use, it's a class piece of kit!.
