DMM600 Duff Moisture Meter

3.3 Display End

3.3.1 Power Switch

A toggle switch turns the DMM600 on and off. A single beep sounds when

the DMM600 is turned on. To conserve battery power, the DMM600 will

automatically turn off after about 5 minutes of inactivity. If the DMM600 is in

the power-saving mode, toggling the power switch or compressing the sample

will restore measurement mode.

3.3.2 Audible Indicator

The audible indicator uses a port to the side of the power switch.

3.3.3 Display

A two-line, 16 character LCD provides measurement results. When the

DMM600 is turned on the display is:

DMM600

Compress sample

When the sample is compressed and measurement made, the display is:

Std Cal: xx%

Freq: xx.xMHz

With Std Cal the standard calibration and Freq the frequency from the

measurement circuit.

If a user-defined calibration is loaded in the DMM600, the display is:

name Cal: xx%

Freq: xx.xMHz

with name the name given to the user defined calibration as specified in

PCDMM software. The display will alternate every 3 seconds between the

standard and user-defined calibration.

3.3.4 Serial Port

The DMM600 serial port is used for direct connection to the serial port of a

computer using a 9-conductor cable. The port should be kept covered with the

plastic cover to protect from damage when not being used. PCDMM is the

interface software.
