SET CABLE LENGTH

Use the Left/Right arrow keys to adjust the Cable Length displayed to the length of the cable under test. The arrow keys will increment or decrement the numbers displayed slowly when first pressed. The step size of change will increase the longer the key is pressed. For simple operation, hold down the key, noting the step size as the numbers change. Release the key momentarily when the number approaches the desired setting. This reduces the step size. Then press the key for individual steps to fine-tune the setting.

Measure VOP - Once the test cable’s length is set and connected to the CE4000, press the Find VOP (F1) function key. The CE4000 will calculate and display the Cable VOP (Figure 2-8).

Measure LEN - The Cable Test mode can also be used to make quick cable length measurements by setting the VOP and pressing the Find LEN (F2) function key. The CE4000 will calculate and display the cable length (Figure 2-8).

Save - Be sure to save the information if you want to use the measured VOP for subsequent cable tests. Press Save (F4) to display the screen shown in Figure 2-9. You must enter a cable type and manufacture in this screen for the information to be saved.
