DEAD TIME
. . . . . . . . . . 0.1 to 100.0 sec
This value is defined as the time difference between a change in % power and the
start of an actual change in rate. The default value is 1.

MAXIMUM POWER
. . . . 0.0 to 100.0%
This parameter is used to set the maximum permissible % power level. The control
voltage output will not exceed this limit. The default value is 100.0%.
DENSITY
. . . . . . . . . . . . 0.50 to 99.99 g/cm
3
This parameter is specific to the material being deposited onto the crystal. It is one
of two parameters that relate the mass loading on the crystal to a thickness.
The default value is 1.00 g/cm

.
Z-Ratio
. . . . . . . . . . . . . . 0.100 to 9.999
This parameter is specific to the material being deposited. It is one of two
parameters that relate the mass loading on the crystal to a thickness.
The default value is 1.000. See
for material density and Z-Ratio values.
