for detector “out of range”. Occurs if error in defining detectors in configuration file
lv
–
for possible too low sum_voltages for reliable Ra calculation (less than 100 mVolts)
rr - for rough "range error". Occurs if error in defining detectors in configuration file
Note: i
t is important to interpret the “tc” and “tf” messages as alignment aids (head “too close” or “too far” for
accurate measurements) only on known smooth surfaces (typically less than 10 to 12 microinches Ra).
Lasercheck may generate a “smooth” Ra value on s
urfaces rougher than 10 to 12 microinches. On surfaces
rougher than these values the “tc” and “tf” messages should be ignored.
max_detector is the integer value of the detector with the maximum voltage on it. This value will always be 2
digits and can range from 01 to 35. The location of the maximum detector voltage is useful for determining
vertical alignment on smooth surfaces only. Refer to the alignment section in the manual.
sum_voltages is the sum of all voltages from detectors 01 to 35. The value will be 7 characters in length
(including the decimal point character) with padding zeros on either end when necessary, and always followed
by a comma.
@03 Request Ra Value
Start conversions when Start trigger input is activated.
Cmd @03# will execute and provide a single Ra value when the start input pin is in the trigger state.
When the start trigger goes inactive, Cmd @03# will remain active waiting to execute a new Ra value when the
input pin triggers again
Sending any other command will make Cmd @03# go inactive

@03,00#<cr-lf> Returns continuous stream of Ra values when the start input pin is in the trigger state.
When the start trigger goes inactive, the Ra stream will stop. Cmd @03,00# will remain active waiting to execute
a new Ra stream when the start input pin triggers again
Sending any other command will make Cmd @03,00# go inactive
