Extension tubes (optional) are available for measurements in deep holes.
A small measurement error can occur when assembling various extension tubes. It is recommended not to use more than 2 extension tubes for a measurement. If possible, use 1 long extension tube instead of several short ones.
Extension tubes can be used up to 1000 mm.
When using extension tubes longer than 500 mm, use the inner probe in vertical position.
Accuracy and proper functioning also apply when used with an extension tube.
