Circuit tester
Circuit tester can measure various electric values. Such as the measurement of the resistor value, the measurement of the voltage, the measurement of the current, the confirmation of the polarity of the light emitting diode etc. This tool is necessary for electronic circuit making.
The circuit teser shown on photograph is an analog type, the measurement result is confirmed with the needle that calls the meter. Besides there is a digital type, the measurement result is confirmed with the digital display. Digital type can easily confirm the result. Even the analog type is able to use sufficiently. I am using and like the analog type.
Fundamentally following items can measure by the circuit tester.
 | DC voltage AC voltage DC current Resistance value |
Some circuit tester can measure the value of capacitor, the value of coil, the characteristic of transistor etc.
