    Yes it takes patients. Have recently repaired a TP20 ortling. You need to get the graticule to line up on the screen around the halfway point. Then move action from zero to full scale. Tapping with a pen or pencil, to set so
    numbers and fringes run true. Then apply retaining compound to fix in place. Use adjustable weights on thread rod to set zero. You can add weights under pan table to get within range of adjustment. I have plenty of the 6 volt lamps for the light source too

    Hi Simon, I have recently been given a Oertling TP30 for calibration, However
    I am finding Difficulty in making a zero adjustment and the readings are quite bad aswell, I have tried adjusting the vertical and horizontal Counter weights but to no effect, I would be most welcome if you could give me any information that may help us to calibrate this item. With Thanks
