TONEcube SETTING TONE SOUNDS
The tone cadence or style can be changed using the TONE switch. Slide the
TONE switch to the left and hold on. With a tone probe, you will hear each
of the five tone sounds for a few seconds. The tone being heard when the
switch is released is now selected.
TONEcube POLARITY & VOLTAGE PRESENCE TESTING
The STAT (status) switch position is used to determine if voltage is
present and what polarity or type it is. The NRM (normal), green LED and
REV (reverse), red LED are referenced to the POTS (Plain Old Telephone
Service) conventions. If the red clip is connected to the tip signal and the
black clip (green phone wire) is connected to the ring signal, the polarity is
that of a 'normal' phone line and line voltage is present.
• Green LED is on: the black lead is more positive than the red lead.
• Red LED is on: the red lead is more positive than the black lead.
• Both LEDs are on: the voltage is an AC voltage.
• When the RJ plug is used: a correctly wired and powered POTS
phone jack will light the NRM, green LED.
Note: The POTS color code convention (black/positive, red/negative) is
the opposite of the multimeter color code convention (red/positive, black/
negative).
The continuity mode is used to determine if a low resistance path exists
between two points.
CAUTION:
If connecting to unknown wires, use the STAT switch
position first to verify no voltage is present. The TONEcube could be
damaged by a voltage being present or cause erroneous results.
Move CONT-STAT slide switch to the CONT position.
1.
Connect the leads to the two locations to be tested. If the resistance
2.
of the circuit is less than about 10,000Ω, the REV, red LED will light.
Return slide switch to STAT position when finished. The TONEcube
3.
draws no power from the battery when the leads are open, but the
leads could touch during storage, draining the battery.
PROBEplus REPLACING THE PROBE TIP
The probe tip can be replaced if it is worn out or damaged with PROBEplus
Probe Replacement Tip Cat. no. VDV999-065
Loosen the screw on the back of the probe nearest to the probe tip
1.
using a #1 Phillips screwdriver.
Pull the old tip out of the probe.
2.
3.
Push the new tip into the probe. The probe body has a keying slot so
the probe can only be inserted completely in one orientation.
4.
Tighten the screw, being careful not to over-tighten. Make sure the
probe tip is firmly held in place by pulling gently on it. If not, tighten
the screw slightly.
TONEcube BATTERY REPLACEMENT
Remove single screw on the bottom back of the TONEcube with a #0
1.
Phillips head screwdriver. Remove battery door.
2.
Recycle exhausted battery.
3.
Acquire a 9 volt alkaline battery (IEC 6LR61, ANSI/NEDA 1640A).
4.
Connect battery cable to new battery observing polarity and place
into battery compartment.
5.
Replace battery door and screw, taking care not to over-tighten it.
