17. Additional Features
Units of measurement
Choice of Units. The Cable Fault Finder will display cable lengths either in
meters or feet.
To change the units to be used, switch the TDR off, then switch on while
holding down the key. The unit in use, either “Meters” or “Feet” will be
displayed.
Toggle from one to the other using the key. To resume normal operation
switch off, then on again.
Tone Generator
In Warble Mode the TDR generates a warbling tone, which is transmitted
down the cable under test and can be picked up with a standard tone probe
like the Triplett Hound 2 or Hound 3 (optional). This facilitates cable tracing.
To select Warble Mode, switch the TDR off, then switch on again while
holding down the key. The message “Warble” will appear on the display.
To resume normal operation switch off, then on.
