Put the nozzle of filming liquid bottle, 2 cm to 3 cm, into the measurement gas inlet port on the
left side of the measuring unit. Fill the equipment with filming liquid gradually up to the
liquid level, between 2 blue lines on the liquid level window. Be sure not to create bubbles.

water not only causes inadequate filming but contaminates the measuring
unit and deteriorates the packing.

measure. The liquid level above or below the upper and lower levels
adversely affect the film creation and measurement accuracy.
