ADJUST
The Adjust (F2) function allows adjustment of the Pulse Width using the Up/Down arrow keys, as shown in Figure 3-23. Typically two pulse widths will be stored automatically, depending on the mode and length of cable under test. Only Pulse Widths stored may be viewed. After pressing the Adjust (F2) function key you may also press the Left/Right arrow keys to adjust the position of the second marker M2. As in the Manual operating mode, the digital display measures the Distance and Loss relative to the placement of the M2 marker. The correct placement for distance measurements is at the beginning of the rising edge of the reflected trace. The Loss measurement is made automatically 1/2 the distance of the pulse width to the right of the marker placement. Pressing the Adjust (F2) key again will turn the adjust mode off.
