Industrial-grade 5-inch color LCD screen is adopted with a resolution of 800×480.

    Six fixed voltage measurement ranges:100V, 250V, 500V, 1000V, 2500V, 5000V. Customized voltage mode from 50V to 5000V is continuously adjustable with a step voltage of 10V.

       Maximum output short-circuit current is 6mA, adjustable in 1mA, 2mA, 3mA, 4mA, 5mA and 6mA.

       Maximum continuous output power is 27W.

       It’s equipped with independent discharge circuit. The tested items can discharge fast after testing.

       It features tested item breakdown protection function and arcing mode; It can continuously operate in breakdown arcing mode to locate weak insulation positions.

       It boasts insulation resistance (IR), dielectric absorption ratio (DAR), polarization index (PI), and step voltage (SV) testing functions.

       It supports two DAR calculation modes: R60s/R30s and R60s/R15s.

       Featuring DC and AC voltmeter functions, it can automatically identify DC and AC voltage signals and measure AC voltage signal frequency.

       It has hardware filters and configurable software filters, which can significantly improve its anti-interference performance.

       Test time under each testing mode is independently stored and won’t affect each other to help use next time.

       Auto-shutdown functions when idle or in low battery. The auto-shutdown time is configurable.

      Standard large-capacity lithium battery with a built-in fast charger; the instrument panel and LCD screen can indicate

      current charging status; With replaceable battery box, users can replace battery packs by themselves.
