KYORITSU 3005A DIGITAL INSULATION / CONTINUITY TESTER
A live circuit warning indicator and buzzer alert the operator if the circuit under test is energized, enhancing safety.
After insulation testing, built-in auto discharge circuitry removes residual charge from capacitive components automatically, and an audible confirmation indicates when it is safe to touch the circuit. The instrument’s microprocessor-controlled dual integration system ensures stable, repeatable measurements even under varying temperature and battery conditions.
Lightweight (≈970 g without batteries) and designed to IEC CAT III 300 V standards, the KEW 3005A is suited for field service, maintenance, and troubleshooting of electrical equipment such as motors, transformers, switchgear, and cables.
- Measurement Capabilities: Measures insulation resistance (up to 2000 MΩ), continuity (up to 2000 Ω with 200 mA current), and AC voltage (0-600V AC).
- Selectable Test Voltages: Offers multiple DC test voltages for insulation testing: 250V, 500V, and 1000V.
- Safety Features: Includes a live circuit warning indicator and buzzer, an auto-discharge function to remove stored charges after testing, and is designed to IEC CAT III 300V safety standards.
- Display: Features a liquid crystal display (LCD) with a 30-segment bar graph to visualize insulation resistance readings.
- Auto Null Function: Automatically subtracts the test lead resistance during continuity testing for more accurate results.
- Durability: Encased in a rugged housing with a dedicated cover for protection against impact, and rated IP54 for dust and water resistance
Applications:
- Measuring insulation resistance in electrical installations.
- Conducting continuity tests on wiring systems.
- Detecting AC voltage presence in circuits.
- Ensuring safety and compliance in electrical maintenance.
