Features signal output: sine wave, triangle, square wave and integrator (selectable through jumper) signal frequency: about 1 kHz (fixed) output level: adjustable from 0 to 100 mVrms (LEVEL potentiometer) Specifications power supply: 9 V battery (not incl.) dimensions: 56 x 40 mm / 2.2 x 1.6" Whadda (Velleman) model: WSAH105 Replaces Velleman MK105 (5410329001056)

This signal tracer /injector has been designed to inject or detect a specific signal into an audio circuit in need of repair (such as amplifiers, radios, tone controls, ...) so as to detect the fault. In this way problems can be traced more easily. The signal tracer may also be used as a simple monitor or amplifier. Specifications signal injector: 0-2.5 Vrms output (adjustable) output impedance: 1.5 kOhm frequency: ± 1 kHz signal tracer: 3.5 mV to 10 Vrms sensitivity (adjustable) gain: 40 dB

Specifications detection range: 5cm - 1.5m (adjustable) detection angle: 5° supply voltage: 10 - 15VDC / 16mA PCB dimensions: sensor: 28 x 95mm / 1.1 x 3.7" base: 48 x 125mm / 1.9 x 4.9" Velleman model: K3502
