H60.0.11.6C-16 Operating Manual GMH 3830 Page 8 of 18 _____________________________________________________ _____________________________________________________________________________ 5.5 Measuring In Wood: Measuring With Two Measuring-Needles Normally wood is measured with measuring-needles. Used electrodes: impact-electrode GSE91 or GSG91, reciprocating piston electrode GHE91. For measuring wood, punch in the measuring-needles across to the wood-grain, having a good contact between the needles and the wood (measuring along wood-grain deviates minimal) Select correct wood-sort (refer to Appendix A). -
