RA_LIMITS
This option accepts two numbers; the first is the minimum and the second is the maximum Ra value of the
surface specification. This sets the specification range for Ra values. If a measured Ra is outside (lower than the
minimum or higher than the maximum) these values pins on the control box output port (Ra_Limit) momentarily
close. An “out of spec” indicator, or automated part rejecter can be connected to these pins to alert operators
and / or reject parts when they are outside of specification.
ANALOG_OUTPUT
LOW_ANALOG
This option is used to configure the low current or voltage setting of the Analog_Out pin of the output
connector. This number shall determine the Ra value that will generate 0 Volts or 4 milliamps output at the pins.
HIGH_ANALOG
This option is used to configure the high current or voltage setting of the Analog_Out pin of the output
connector. This number shall determine the Ra value that will generate 10 Volts or 20 milliamps output at the
pins.
Jumper Settings for Setting Analog Output to 4-20 mA or 0-10 V
Jumpers JP2 and JP3 on top board inside of control box must be set to configure 0-10V voltage or 4-20 mA
current output. Set JP2 and JP3 to “C” for 4-10 mA current output or to “V” for 0-10V voltage output.
RA_THRESHOLD
The Ra threshold set by factory for optimizing calibrations on low or high Ra surfaces. Default is -1.
CAL_TYPE
Set by factory for optimizing calibrations. Options include:

POWER

EXPONENTIAL

“CAL1, CAL2, CAL3, CAL4, and CAL5”.
CALIBRATION
Set by factory for optimizing calibrations. See discussion in Appendix C - Calibration Procedures.
Default.set setup files
Many different setup files can reside on the controller so users can scroll to, and use these different setups for
different applications. The first setup file to “load” when the controller is started is typically the most recent
setup file that was loaded onto the controller. If desired, one setup file can be configured to always load
whenever the system is turned on by naming the setup file “Default.set”. The first two lines will read:
RECEIVE_NAME= default.set
FILENAME= default
