WTF do you get that from? The last one I took in for a calibration
certification (same as the 2yr test) after it had the seal changed on
the gearbox drive was under £40.
A manufacturer would have the equipment on site.
If it needs recalibrating, it doesn't cost anywhere near £400. In fact,
I reckon £400 is probably about what it costs to fit a new one.
