Operating Instructions
Once a connection has been established, CT Viewer™ can be granted remote control over the
operation of the CT100. Please consult the CT Viewer™ manual for details about starting
remote control and manipulating a remote trace.
Cable type
The CT100 has a library of common cable types. Vp for these cable types can be loaded from
the library.
Load a cable type's Vp
1) Press the LIBRARY button. The Library menu appears.
2) Select Cable Type from the menu. An interface appears that allows you to scroll
through the cable types with the M-FUNCTION knob.
3) Select the desired cable type and press OK. Vp is now set to the value for that cable
type.
User editable cable types
The CT100 is also able to save and load custom cable types.
1) Press the LIBRARY button to access user editable cable types. There are two new
items on the Library menu: Add Custom Cable Type and Load Custom Cable Type.
2) When Add Custom Cable Type is selected, a window appears for entering a cable type
name, a Vp for pulse velocity, and an expected impedance. When the window first
appears, Vp will be set to the current system Vp, while impedance defaults to 50 Ohms.
The other menu option, Load Custom Cable Type, opens a window with all of the added
user types available for selection. Use the M-FUNCTION knob and the Select menu option
to load a particular cable type. When selected, the operating Vp is changed to match the
selected cable type.
The user-added cable types are stored and accessed separately from the standard cable
types, which are still available through the Cable Types menu item.
