WET

The WET command without a parameter shows the scaling factor that
normalizes the RAINCAP
state to be 1.00. A typical value is close to 0.0015.
DRD WET SCALE 0.00169
The WET ON command is used to set the parameter. The RAINCAP
measuring surfaces must be coated with a wet cloth or immersed in water
for at least 30 seconds, when the WET ON command is given. Make
sure the wet cloth touches only the RAINCAP
