This instrument adopts low-loss high-ratio of inductance energy storage DC voltage converter to change 12V into DC 250V/500V/1000V. It uses digital LCR Bridge for resistance measurement and the insulation resistance test. It has many advantages: lightweight, wide measuring range, backlight display, test lock, auto power off and other functions. It can also be used for electricity measurement with advanced appearance and stable performance.

Features:
Wide measuring range: up to 2000MΩ 1000V with accuracy of ±(4% of reading+2 digits).
Large LCD display(90 * 48mm), with backlight, max. display "1999".
Data hold and auto power off function.
Over range indication: display "1".
Low power consumption: less than 300mW at no-load measurement.
Applied in insulation resistance testing of motors, cables, electrical equipment, telecommunication equipment, etc.
