Topping up the
index-matching
fluid
If no more index-matching fluid emerges when turning the metering wheel in clockwise
direction, top up with new index-matching fluid.
The tool bag contains a plastic syringe filled with index-matching fluid (see next figure).
Turn the metering wheel in counter-clockwise direction until you can remove it. Located
in the lid is a cavity for holding the index-matching fluid.
Use the syringe to fill the cavity with the index-matching fluid (approx. 0.1 ml) (see next
figure).
Screw the metering wheel back on.
