Preparing the sensor

Removing protection cap from sensor

NOTICE

Negative pressure causes damage to the sensor's membrane cap

‣

If the protection cap is attached, carefully remove it from sensor.

1. When supplied to the customer and when in storage, the sensor is fitted with a

protection cap: First release just the top part of the protection cap by turning it.
