In accordance with EN61326 +A1 +A2 (appendix A, class B), additional errors: < 1% FS.
When connecting long leads adequate measures against voltage surges have to be taken.
The electrode connections have to be protected sufficiently against ESD pulses, if the
device is used in areas with risk of ESD.
