Features:
Multiple gear options, fast testing: Key switch gear, 250/500/1000/2.5KV/5KV/10KV can be selected for testing according to needs.
Automatic discharge, overload protection: When testing the insulation resistance of a load, the load will be automatically discharged after measurement - double protection, worry-free measurement.
One-key storage, no need to transfer: When the measurement is completed, short press the "MEM" button to lock the current display data and automatically number the memory. Data storage of 500 groups.
Connected with computer: With USB interface, software monitoring, stored data can be uploaded to the computer to save printing.
Alarm setting: When the measured voltage value is greater than the alarm setting value or the insulation resistance value is less than the alarm threshold, the instrument will flash and emit a "beep-beep-beep" alarm sound.
LCD display with backlight: Well matches different environments, values can be seen clearly even in sunlight/dark environment.
