Hauser

The sensitivity of the concrete measurement can be changed by selecting another

calibration curve.

The standard calibration curve

"Cal. No.: 4"

is set by default for concrete.

• Do not change this setting, or only change this setting if you are measuring a

material other than fresh concrete

• For more information, please contact the manufacturer's Service Department
