General Testing procedure
Ensure the correct test leads are firmly fitted into the sockets of the instrument.
Switch on the instrument. The instrument will display the start screen for a couple of seconds, followed by a trace. The instrument will
remember the settings last used.
If necessary, adjust the display contrast and distance units to the preferred settings. Use the setup mode to set the velocity factor and
impedance of the cable about to be tested. Refer to ‘Velocity factor’ later in this text for details.
