Kyoritsu 3007A Digital Insulation / Continuity Tester

kyoritsu insulation tester 3007a

The Kyoritsu 3007A Digital Insulation/Continuity Tester is a sophisticated instrument designed to provide comprehensive testing capabilities for both insulation resistance and continuity. It stands out in the market for its accuracy, ease of use, and robust set of features tailored for professional electricians and technicians involved in the maintenance, troubleshooting, and testing of electrical systems.

One of the key features of the Kyoritsu 3007A is its bar graph display, which provides a visual representation of insulation resistance. This feature is complemented by the ability to detect and display external AC voltage, along with a flashing symbol warning, ensuring users are aware of potential safety hazards during testing.

The device includes an auto null function, a critical feature that automatically compensates for the resistance of the test leads. This ensures that the continuity resistance measurements are accurate and reflect only the resistance of the component or circuit being tested, not the leads themselves. Additionally, the 3007A delivers a 200mA measuring current during continuity tests, which is ideal for detecting and measuring low resistance values accurately.

For enhanced user convenience and energy efficiency, the 3007A is equipped with the Trac-Lok mode. This mode conserves battery life by reducing power consumption during insulation and continuity tests when the device is idle. A live circuit warning buzzer further enhances safety, alerting the user to the presence of hazardous voltages.

Another user-friendly feature is the automatic discharge function. When the test button is released, the device safely discharges any electrical charges stored in the circuit under test, protecting both the user and the equipment from potential shocks.
