H68.0.01.6C-06 Operating Manual GMK 100 page 10 of 14 _____________________________________________________ _____________________________________________________________________________ The values measured with CM-method and oven-dry method (%u) may differ for conversion [% u] to [CM-%] some materials. Especially for building for concrete and cement screeds materials containing cement CM- measurements will always get lower values than oven-dry measurements. -
Page 11: Adjustment
H68.0.01.6C-06 Operating Manual GMK 100 page 11 of 14 _____________________________________________________ _____________________________________________________________________________ 14 Adjustment The accuracy can be checked with the testing probe PW 25 (optional accessories). Select the material “rEF” and run the zeroing function (p.r.t. chapter 6.5). Lay the device onto the testing cube. If the device displays a different value than the value printed on the cube for the GMK 100, you can use the slope correction to adjust the device: Displayed value rEF =(measured value rEF * (1 + slope correction / 100 ) Follow these instructions to adjust the device:... -
