Description
Overview
GAOTek Megohmmeter with Data Storage (Auto Voltage Release) measures insulation resistance and displays automatic release of voltage and comes with 18 groups of data storage capacity. This device has computer technology as kernel and LSI combined with digital circuit to measure insulation resistance. It is equipped with strong measurement and data processing software, displays automatic release of voltage, has stable features and is easy to operate. The instrument will Auto power off if there is no operation in 15 minutes after completion of the test. Polarization Index test can be conducted between any two time in order to auto-test the resistance ratio according to the setting.
