DMM600

Datalogger Considerations

The DMM600 is a stand-alone product so datalogger compatibility is not an issue.

Software

PCDMM Software is supplied with the DMM600. It interfaces with the DMM600 using serial communications, and is used to download and upload calibration coefficients, monitor the battery voltage, and reset the DMM600.

Calibration Coefficients

A standard calibration converts the output of the measurement circuit to volumetric water content. User-derived calibrations can be downloaded using PCDMM software. These calibrations are useful when using the DMM600 with atypical materials. Guidance is provided in the operating manual for deriving calibrations. This feature can also be used with known duff bulk density to convert result to gravimetric water content. Measurements derived from the standard and user-defined calibrations are alternately displayed on the LCD if a user-defined calibration has been downloaded.

Sieve and Carrying Case

The DMM600 comes with a sieve and case. The sieve fits in the opening of the sample chamber. Duff is moved through the wire mesh of the sieve to break up large fragments and improve measurement accuracy in duff materials with a large range of fragment sizes.

The case eases transport and provides storage for the sieve and small items such as a spare battery, screwdriver, and pencil.
