The base casting is 13 Inches (330mm) in diameter and is located inside the
chassis under the bottom panel. It contains (8) 1/4-20 tapped holes for
mounting, located on bolt circle diameters of:
(4) - 12.0 In BCD, (4) - 6.0 In BCD. Each set is offset 45 degrees.
The 13 In diameter area of the base is the true load bearing surface. None
of the other exterior portions of the chassis should be used for mounting to
jigs or fixtures.

■ Display Readout Polarity
This selection controls how the LT360 represents the
position on the front display of the chassis, and here in the software. When
set to UNIPOLAR, the position is shown from of 0 to 360 degrees. All
position values are positive. When it is set to BIPOLAR, the range will be 0
to ±180 degrees. Both positive and negative values will be shown.
■ Analog Output Polarity
This selection controls how the LT360 generates the DC
voltage output at the Analog Output connector. When
set to UNIPOLAR, the LT360 will produce voltages in the
range of 0.000 to +3.600 volts. All position values are positive. When it is
set to BIPOLAR, the range will be 0.000 to ±1.800 volts. Both positive and
negative output.
■ Analog Input Polarity
This selection controls how the LT360 interprets the DC
voltage received at the Analog Input connector. When
set to UNIPOLAR, the LT360 will accept voltages in the
range of 0.000 to +3.600 volts. All position values are positive. When it is
set to BIPOLAR, the range will be 0.000 to ±1.800 volts. Both positive and
negative values are used.
Voltages higher than the allowable range for the selected mode are invalid.
The LT360 has a scale factor of 10mV/deg for the analog input/output.
