Key parameters
Supply
2 × 9 V batteries (generator and probe, one each)
Ambient temperature
Operating 0–40 °C, ≤80% RH; storage −10–50 °C, ≤80% RH
Approvals
CE
Tone Output
1 kHz (±15%), square wave ~4.3 Vrms (10.2 V p-p approx.); continuous or wobble
Functions
Wire/cable tracing; continuity (~10 kΩ extinguish); tip/ring ID; clear/busy/ringing line test
Probe
Insulated inductive probe tip; built-in speaker with sensitivity control; headphone jack
Fits cable tracing and pair identification where you need an Extech 40180 tone generator with amplifier probe, continuity check, tip/ring ID, and RJ11/RJ45 connectors.
Key advantages
- Tone — 1 kHz (±15%) square wave ~4.3 Vrms; continuous or wobble
- Functions — Wire/cable tracing; continuity (~10 kΩ extinguish); tip/ring ID; clear/busy/ringing line test
- Probe — Insulated inductive tip; speaker with sensitivity; headphone jack
- Connections — Alligator clips; modular RJ11 and RJ45
- Protection — Tone generator protected for voltages <100 VDC; CE
Typical applications
- Network and telecom cable tracing.
- Continuity and tip/ring identification.
- Clear/busy/ringing line status checks.
Selection guide
- Connectors — Clips vs RJ11/RJ45
- Headphone — Noisy environments
- Batteries — 2× 9 V (generator + probe)
- Voltage caution — <100 VDC protection class
Common mistakes
- Connecting to live high-voltage circuits beyond protection.
- Tracing without reducing probe sensitivity in noisy bundles.
- Ignoring line-status LEDs before tone inject.
When to RFQ / what to tell us
- Kit/case; quantity; ship-to.
