The DRY command is used to set the dry signal end of the DRD12
signal normalization calculation.
When you type
DRY
the output is, for example, the following:
DRD DRY OFFSET 915.6
The DRY OFFSET value must be between 850 and 980 when the
DRD12 hardware operates normally. The DRY command shows this
parameter. The parameter is set by the DRY ON command.
When you type
DRY ON
the WET command without a parameter shows the scaling factor that
normalizes the DRD12 signal change from the dry state to the wet
state to 1.00. A typical value is 0.0015. An example is shown in the
following:
WET
DRD WET SCALE 0.00169
The WET ON command is used to set the parameter. The DRD12
measuring surfaces must be coated with a wet cloth or immersed in
water, when the WET ON command is given. An example of the
command is given below:
WET ON
AN Command
The AN command can be used continuously to display the selected
analog monitor channel. The channel ID can be used as a parameter,
instead of the channel number. Thus, the AN AMBL command is the
same as AN 12.
The message consists of the raw binary number from the A/D
converter and the corresponding scaled and filtered value.
