Features 6 selectable voltage ranges: 500V, 1000V, 2500V, 5000V, 10000V, and 15000V, with a maximum test range reaching 30 TΩ. It also includes a manual voltage step-up function.

● Designed in strict compliance with safety standards.

● Insulation resistance range: 20 TΩ at 10 kV.

● Adjustable short-circuit current, with a maximum output of 3 mA.

● Automatically displays test values for the Polarization Index (PI) and Dielectric Absorption Ratio (DAR). It is also capable of measuring leakage current and capacitance, as well as performing Dielectric Discharge (DD) and Step Voltage (SV) tests.

● Superior anti-interference performance: the instrument maintains test accuracy even when subjected to interference currents reaching 2 mA.

● Features AC/DC voltage measurement capabilities for the circuit under test, with automatic recognition of AC or DC sources.

● Rapid discharge function for capacitive loads: when testing cables, manual discharge is unnecessary as the instrument automatically and quickly discharges the stored energy.

● Dual Power Supply Modes: Powered by a lithium-ion battery with an operating life of up to 6 hours.

The unit supports charging while in operation. In the event of a power outage, it automatically switches from AC mains power to battery power.

● Full Chinese-language interface with operational prompts in Chinese, ensuring simple and intuitive operation. The display also features an analog bar graph for insulation resistance readings. ● Digital Filtering Function: Employ the filtering function whenever external influences cause deviations in the displayed values to mitigate their impact.

● Comprehensive Protection Features: Includes a built-in fuse-blown indication function.

● Data Storage Capability: Supports data saving and export. ● Safety Specifications
