Specifications
How does a voltage and continuity tester transmit signals?
Probe Contact:Voltage Measurement: Touch the red probe (positive) to the positive terminal of the circuit under test, and the black probe (negative) to the negative terminal or ground.
Continuity Test: Touch the two probes to two points in the circuit to check if there is conduction between these two points.
Signal Conduction:Voltage Signal: When the probe contacts the point under test in the circuit, the tester's internal circuit conducts the voltage signal from the circuit through the probe.
Resistance Signal: During a continuity test, the tester's internal circuit conducts the resistance signal between the two points in the circuit through the probes.
