MRT-10 Insulation Resistance Tester
• Covers IR/DAR/PI/DD/SV full-function test modes, and realizes dual-mode calculation of DAR absorption ratio.
•The three-in-one operation matrix of key control, touch screen, and knob mouse simplifies the operation link to the extreme, making the test more flexible and faster.
• Multi-level voltage range can be switched arbitrarily, and custom voltage mode is supported.
• Real-time recording and visualization of insulation resistance-voltage-current time curve, supporting transient analysis of insulation state.
• With AC and DC voltage measurement function, it can automatically identify voltage type and measure AC frequency.
•With cable length measurement function, equipped with controllable hardware and software filters, the anti-interference performance is significantly improved.
• Three safety barriers, including independent discharge circuit, sample breakdown protection and arc detection, not only protect the equipment safety, but also accurately lock the insulation weak points to prevent accidents.
•High and low voltage circuit full isolation architecture to ensure the safety of operators.
• With USB storage function, data can be exported to USB flash drive in batches for easy backup and migration.
