I recently acquired a faulty Oertling TP 40 laboratory balance that was being thrown out by my university. It's an 800g capacity mechanicalbalance which reads down to 0.01g. The problem is that the glass scale (an image of the scale is magnified by a system of lenses and mirrors and projected onto a screen) has come loose and is now misaligned. I'd like to fix the balance, partly for fun and partly because it would be useful to me. I presume that the glass scale needs to be carefully adjusted, then glued in position and the balance calibrated. Does anyone have experience of this type of balance and know what is involved in calibration? Calibration doesn't need to be highly accurate; if it was accurate to 0.1g that would be fine. Or perhaps someone knows where I could obtain a service manual? Any suggestions would be much appreciated.
