Description of the Operating Parameters
In Setup Mode, the selected parameter appears on the top line of the LCD display
along with its corresponding value appearing on the bottom line. A detailed
description of each parameter is given below.
1. Select Units - sets the units to Inches or Millimeters.
2. Analog Output - sets the full-scale range of the Analog Output. Because
the Analog Output has 16-bit resolution and is updated continuously at a
rate of 100 times per second, it can be used as a strain feedback signal for
closed loop applications. The full scale range of the Analog Output
depends on the system of units set in the Select Units parameter. The full-
scale range choices for the LX 500 are:
0.1 in = 10 V (5 V) (for inch units)
2.0 mm = 10 V (5 V) (for mm units)
0.2 in = 10 V (5 V) (for inch units)
5.0 mm = 10 V (5 V) (for mm units)
0.5 in = 10 V (5 V) (for inch units)
10 mm = 10 V (5 V) (for mm units)
1.0 in = 10 V (5 V) (for inch units)
20 mm = 10 V (5 V) (for mm units)
2.0 in = 10 V (5 V) (for inch units)
50 mm = 10 V (5 V) (for mm units)
5.0 in = 10 V (5 V) (for inch units)
100 mm = 10 V (5 V) (for mm units)
Note The full-scale range choices for the LX 1500 are:
0.1 in = 10 V (for inch units)
2.0 mm = 10 V (for mm units)
through
20 in = 10 V (for inch units)
500 mm = 10 V (for mm units)
Six intermediate ranges are also included.
3. Target Distance - Sets the Target Distance. This is the distance from the
front panel of the Laser Extensometer to the targeted surface of the
specimen. This parameter depends on the system of units set in the SELECT
UNITS parameter. The choices appear on the LCD display.
