MS-3126A, Insulation Resistance Tester

This high-voltage insulation resistance tester features five measurement ranges: 500V, 1000V, 2500V, 5000V, and 10000V, with a

 maximum testing capacity of 10TΩ.

Designed strictly according to safety standards.

1. Insulation resistance range: 10TΩ@10kV; adjustable short-circuit current, maximum up to 10mA.

2. Automatically displays polarization index (PI) and induced absorption ratio (DAR) test values; can test leakage current and 

capacitance.

3. Excellent anti-interference performance; maintains test accuracy even with interference current reaching 2mA.

4. Rapid discharge of capacitive samples; automatic rapid discharge is achieved during cable testing, eliminating the need 

for manual discharge.

5. Two power supply options: lithium-ion battery power supply provides up to 4 hours of runtime (10000V@100MΩ test resistance).

6. Can be charged while in use. Automatically switches from AC power to battery power during power outages.

1. AC Power: 220V±10% 50-60Hz 20VA

2. Battery Power: 16.8V Lithium-ion Rechargeable Battery

3. Battery Life: Approximately 4 hours at 10000V@100M

4. Test Voltage Accuracy: 100% to 110% of nominal value

5. Current Measurement Range: 10mA

6. Current Measurement Accuracy: 5% +0.2nA

7. Short Circuit Current: 2 to 10mA Adjustable Output

8. Capacitance Measurement Range: 20uF

9. Capacitance Measurement Accuracy: 15% +0.03uF

10. Capacitor Discharge Rate: From 10000V to 10V in 0.5 seconds µF
