Turing the measuring cell against housing
Description
You can turn the measuring cell against the housing. Turning simplifies the transmitter
operation in the case of an angled installation environment. The buttons and the current
connection can thus also be operated for an external measuring device. The display also
remains visible in enclosure covers with an inspection window.
Only limited turning is permissible! The turning range
① is marked at the foot of the
electronic housing. An orientation mark
③ is provided at the throat of the measuring cell.
This mark must remain in the marked section when turning.
