Using Tone Mode
Tone Mode is used to trace cables by sound. Selection of this mode emits
a cadence from the unit through the connected cable. Cadence is detected
by a tone probe.
When Tone Mode is in use, the connected cable is tested for
the presence of voltage. If detected, a dynamic voltage warning
displays until the unit is disconnected from the voltage source.
1. Connect a cable to the Snap Shot™. Use connection accessories
according to the type of cable you are testing.
2. Press the POWER button to turn the unit ON.
3. Press the TONE button. The LCD display screen updates with the
following symbols and icons (see Figure 11):
▪ Two musical notes blink in the lower right corner to indicate
Tone Mode is in use.
▪ The last selected cadence (HI, LO, HL1, and HL2) appears in the
upper right corner.
▪ The adjustment indicator appears to the left of the cadence
indicating the cadence can be adjusted.
4. To adjust the cadence, press the UP and DOWN buttons until your
desired selection updates in the LCD display screen.
5. Use the tone probe to trace cables.
