KEW3021A 125V-1000V insulation resistance meter is a digital insulation resistance meter for measurements in low-voltage installations below 600V with a test voltage of 125/250/500/1000V. The meter has the function of checking the continuity of the circuit (acoustic signaling). It also meets the requirements of the safety standards: IEC 61010-1 CAT III 600V, pollution degree: 2 IEC 61010-031 (test leads). It has a solid and small and light housing. During the measurement of insulation resistance, electric charges accumulate in the capacitive elements of the circuit, which are automatically discharged after the measurement is performed. After the measured circuit is discharged from the display. The electric shock symbol disappears and the LED turns off.

• 3 in 1: insulation resistance measurement, continuity test, AC / DC voltage measurement.
• Measurement 2.5 times faster than on older models.
• Continuity test with 200mA current.
• PASS / FAIL comparator function with sound signaling.
• Compensation of wire substance during continuity measurement.
• Internal memory - 99 measurements.
• Backlit LCD screen.
• Safety Lock system - additional protection for 500V and 1000V measurements
