Product Description
This probe produces a tone that varies with resistance, capacitance, or voltage. Designed to check continuity, compare circuit resistances, check capacitors, diodes or LED and trace audio signals (up to 1 KHz). Will test live circuits up to 130 VDC or AC (AC is modulated tone). Because the probe is current limited, it will not generate the high current surges normally produced by lamp and buzzer type testers. The probe will not harm any circuit. Sharp pointed tip on one end and a minigator clip on the other. Cable length 36". 9 Volt battery included. Size 7" x 1.2" x 0.9"

Resistance:
0 Resistance (probes shorted) "REFERENCE TONE" as resistance goes UP to 1 meg ohm, Frequency goes DOWN to 10Hz.

DC & AC Voltage:
DC RANGE: 0-130 volts MAX
0 volts- "REFERENCE TONE"
To +130 volts- Frequency goes UP with voltage
To - 8 volts- Frequency goes DOWN with voltage

AC RANGE: 0 to 130 volts MAX Frequency goes UP with voltage, and is an AC modulated tone.

Capacitor:
NON-POLARIZED CAPACITORS (ceramic, mylar, ect.)
Less that .01 mfd. - No Tone
.01 to .5 mfd. - One click
.5mfd to 3000mfd. - Tone changes from High Freq. down to 10hz.
