  • Page 4: Overview

    Operation The Combine Moisture Meter 100 (CMM100) is intended for use on either a combine harvester or a grain drier, and is used in conjunction with an RDS Grain Moisture Sensor to continuously monitor crop moisture content. As the grain flows over the sensor, the CMM100 provides a continuous, dynamic display of the grain moisture content, and the option to display the crop temperature at the press of a button.

  • Page 5: Calibration

    The CMM 100 has factory-default calibration settings for each channel A to F. These settings assume channels A to F are assigned to the following crop...

  • Page 6: Operating Mode

    CMM 100 : INSTALLATION, CALIBRATION AND OPERATION Operating Mode Startup On starting, the instrument should power on. If not, switch it on from the rear-mounted switch. The instrument first displays the software version installed e.g. "A.501" "E.001" "r.006" indicates software version WZ501-001 rev.06...

  • Page 7: Correcting The Moisture Reading

    CMM 100 : INSTALLATION, CALIBRATION AND OPERATION Correcting the Moisture Reading The grain moisture reading should be checked periodically against a reading from a reference moisture meter, particularly when combining oily or dirty crops, since the sensor can produce a false reading due to extraneous material adhering to it.

  • Page 8: Excess Moisture Content Alarm (Harvesting)

    CMM 100 : INSTALLATION, CALIBRATION AND OPERATION Excess Moisture Content Alarm (Harvesting) If the moisture content exceeds the preset threshold, the display flashes continuously and the alarm beeps every 30 seconds. NOTE: If fitted, the (optional) external audible alarm unit will operate in tandem with the instrument internal buzzer.

  • Page 9: Set High/ Low Moisture Content Alarm Threshold

    CMM 100 : INSTALLATION, CALIBRATION AND OPERATION 2.6.2 Set High/ Low Moisture Content Alarm Threshold Having first set the "HIGH / "LO" alarm option (section 2.6.1), you can then individually set the alarm threshold (% M.C.) for each channel as desired.

  • Page 10: Calibration Mode

    CMM 100 : INSTALLATION, CALIBRATION AND OPERATION Calibration Mode Navigating the Calibration Mode Press and hold the button as you switch the instrument on, and continue to hold for 5 seconds until the instrument enters the calibration mode. The instrument displays "CAL" then "ALAr" (for the channel last selected in Normal Operating Mode), then the current moisture alarm threshold setting (xx.xx).

  • Page 11: Programming A Calibration Setting

    CMM 100 : INSTALLATION, CALIBRATION AND OPERATION NOTE 1: If the operator wishes to programme the instrument for alternative crops, then they can if necessary, seek advice from either their RDS distributor or the Factory Service Department NOTE 2: The factory-default settings will be restored after a "Power-On Reset ".

  • Page 12: Factor A ("A.fac") / Factor B ("B.fac")

    CMM 100 : INSTALLATION, CALIBRATION AND OPERATION Factor A ("A.FAc") / Factor B ("B.FAc") May require changing if harvesting / drying crops other than the default grain types. To edit - Ref. section 3.2. Factor C ("C.FAc") This setting is the Moisture Correction Factor, required to match the moisture content reading of the instrument to that of a reference moisture meter.

  • Page 13: Display Smoothing Factor

    CMM 100 : INSTALLATION, CALIBRATION AND OPERATION Display Smoothing Factor This value determines how steady the moisture content display remains, when reacting to variations in moisture content during harvesting /drying A higher value (%) gives a more averaged (steadier) reading.

  • Page 14: Diagnostic Mode

    CMM 100 : INSTALLATION, CALIBRATION AND OPERATION Diagnostic Mode Press and hold the button as you switch the instrument on, and continue to hold for (5 seconds) until the instrument enters the diagnostic mode. The instrument displays "dIAG" and then defaults to channel A (see table 1).

  • Page 15: Data Logging

    CMM 100 : INSTALLATION, CALIBRATION AND OPERATION Data Logging The instrument continuously outputs a line of data every second. A 'Wizard Upload Lead' (Pt No. S/CB/327-1-030) is required, and suitable data capture software must be Connect 'Wizard installed on your PC.
