1000V Insulation Resistance Meter Ground Tester Portable Megger Megohmmeter Volt

Description

Insulation Resistance Measurement
【Megaohm Meter】This digital Insulation Resistance Tester DIRT supports 3 different testing voltage options (250, 500 and 1000VDC) to use in meausring insulation resistance ohm from 0.1MΩ to 2GΩ with ± 4% accuracy. Display insulation resistance value specifically, not just a range.
【Digital Multi Tester】Not just an mega meter , but also an electrical multimeter with 1999 counts display, which can measure AC voltage up to 750V with ±1.0% accuracy, test DC voltage up to 1000V with ±0.5% accuracy and troubleshoot continuity with buzzer.
【Safe & Reliable】Designed with high voltage and short circuit buzzer alarm and anti-high voltage circuit feature, this handheld megohmmeter could be your reliable insulation measuring tool in testing heated cable and wiring insulation, like Schluter's floor heating cables, thermostat and industrial generator winding etc.
【Easy to Use】Featuring with 3.5" backlight HD LCD screen and data hold button, this digital megohmmeter makes it easy to read and record the electric measurements even in low-light conditions. Nice field resistance tester for a quick electric component/motor check.
【Accessories & Warranty】Only 1.1 pounds lightweight insulation resistance tester comes with 2pcs test leads, 2pcs crocodile alligator clips, 72cm detachable strap and multimeter protective hard shell. Digital mega meter comes with 180 days quality warranty.
Note: (1) Press the circular test button and rotate it to the right to lock it to connect the test. Rotate it to the left to release the connection test;
(2) When the circular test button is pressed, the high voltage red warning light will light up, and the high voltage display symbol will appear on the screen. At the same time, a "beep beep" alarm sound will sound (when the measured insulation resistance is about 5% of the range or there is a short circuit, the buzzer will sound a long warning)
