Select type of temperature coefficient: The upper display shows the
last configured temperature coefficient type (Lin or PUr). Press ▲ or ▼
key to select the desired type based on type of your process liquid.
PUr : Pure water temperature coefficient: Select this if your process
liquid is pure water or ultra pure water.
Lin : Linear temperature coefficient: Select this for all other
process liquids
Press ENT key to confirm your selection.
If PUr was selected:
The monitor reverts back to tC screen
