Ensuring water tightness!
The product guarantees protection from spray water, rain or accidental immersion in
water. This protection for the plug connector is only guaranteed when plugged in.
Moisture or contaminants on the contacts can result in incorrect measurement results.
– Protect contacts from soiling and moisture!
– Dry off damp plug connectors as quickly as possible!
NOTE
The temperature measurement can be influenced by conductive liquids on the banana
sockets. We recommend always keeping the connections dry.
