– Open burette valve to fill its tip. Add liquid in
burette until level reaches 0 cc.

NOTE: The liquid level in cylinder must not drop
for a few seconds after filling. If so, there is a
leak between piston and cylinder. The recorded
volume would be false.
– Let burette stand upward for about 10 minutes,
until liquid level is stabilized.
– Read the burette scale to obtain the quantity of
liquid injected in the combustion chamber.
