Please note the hints by the menu items. For configuration of the device press "Menu"-key (key 4) for 2 seconds, the main menu will be shown (main display: “SEt”). -
Page 7: Some Basics Of Precision Material Moisture Measuring
H60.0.13.6C-17 Operating Manual GMH 3851 Page 7 of 22 _____________________________________________________ _____________________________________________________________________________ 5 Some basics of precision material moisture measuring 5.1 Measuring method The electrical resistance depends on the material moisture in many cases. Therefore the device measures the (possibly extremely high) values of resistance and converts them to the displayed value by means of integrated characteristic curves. -
Page 8: Measuring In Wood: Measuring With Two Measuring-Needles
H60.0.13.6C-17 Operating Manual GMH 3851 Page 8 of 22 _____________________________________________________ _____________________________________________________________________________ 5.6 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). -

H60.0.13.6C-17 Operating Manual GMH 3851 Page 9 of 22 _____________________________________________________ _____________________________________________________________________________ 5.7.3 Measuring Split the log: Use an suitable axe for splitting. Fast working splitting machines can produce heat which may falsify the measuring. Preparation of core temperature measuring of log: Drive in the impact electrode, put temperature probe into the generated hole. -

H60.0.13.6C-17 Operating Manual GMH 3851 Page 13 of 22 _____________________________________________________ _____________________________________________________________________________ 7.2 “Func-CYCL“: Automatic recording with selectable logger-cycle-time The Logger-Cycle-Time is selectable (p.r.t. Configuration). For example “CYCL“ = 1:00: A measuring is recorded after each 60 seconds. Special feature of this logger function: The device will change to a ‘sleeping state’ during the measurings (lower display shows a count-down to the next measuring). -
Page 14: Output
H60.0.13.6C-17 Operating Manual GMH 3851 Page 14 of 22 _____________________________________________________ _____________________________________________________________________________ 8 Output The output can be used as serial interface or as analogue output (0-1V). If none of both is needed, we suggest to switch the output off, battery life then is extended. 8.1 Interface - Base address ('Adr.') By using an electrically isolated interface converter USB 3100 N, GRS 3100 or GRS 3105 (accessory) the device can be connected to a PC. -
