TM-350/400 Operating Manual
Both of the rate and the thickness DAC range selections work the same. Table 7-2
shows the settings to select one of the four the available ranges.
With the range set to 999, a thickness of 0.999 KÅ would correspond to an output
of 999/999x5 volts or 5 volts. A thickness of 0.900 would correspond to an output
of 900/999x5 volts or 4.5 volts. With the range set to 5000, a thickness of 1.000 KÅ
would correspond to an output of 1000/5000x5 volts or 1.0 volts.
To select between two or three digit conversion, a set of DIP switches (S16
switches 1 and 2) are provided on the back of the front panel. With J2 (Rate) or J3
(Thickness) installed (default), the DAC is set for three digit conversion. If the
jumper is removed, the DAC is set for two-digit conversion.
