Displaying Data
Displaying the
Transducer Signal (cont.)
In addition to the functions available on the option bar, some of the
numeric keys are used to specify which transducer signal is displayed
and to scale the resulting graph. Table 2-7 below lists these functions.
In summary, three basic functions are performed with the numeric
keys:
•
Signal Selection:
use the “1” and “2” keys to select a transducer
signal for display by scrolling through the list of available signals.
•
Vertical Scaling:
The “4” and “5” keys are used to scale the graph
vertically. Each press of the “4” key doubles the height of the
graph, while each press of the “5” key halves the height of the
graph. The three available scale factors are 1x, 2x and 4x.
•
Horizontal Scaling:
The “7” and “8” keys are used to scale the
graph horizontally. Each press of the “7” key doubles the
T INC
value (2x horizontal compression), while each press of the “8” key
halves the
T INC
value (2x horizontal expansion). The four
available compression ratios are 1x, 2x, 4x and 8x.
To return to the standard data screen, either select
EXIT
from the
option bar or press the
[EXIT]
key on the keypad.
