Description
Notice:
The standard package does NOT include batteries. Because international air shipping prohibits shipping liquids, dust, and batteries, we can’t put them in the package box.
ETCR3480B series insulation resistance tester, also known as megohmium meter, insulation resistance tester, for insulation resistance testing.
This instrument is a high-performance digital type instrument, with large LCD display with backlight display, data hold, automatic discharge, automatic shutdown and other functions. The instrument has the functions of test synchronization and voltage monitoring. When the loop voltage is greater than 36V, the instrument will prohibit the test to protect the safety of the objects and personnel tested.
The easy-to-operate instrument, insulation resistance value, test time and output voltage display with the same display, also have the functions of dielectric absorption ratio (DAR) test, bias index (PI) test, AC voltage test. Maximum output voltage of this 5000V series instrument, the highest test resistance value 400gigaohms, maximum short-circuit current 2mA.
The complete device of the ETCR3480B series insulation resistance tester is beautiful, wide range, high precision, high resolution, easy to operate, convenient to carry, accurate and reliable, stable performance, strong anti-interference ability.
And with shockproof, dustproof and moisture-proof structure, which is telecommunications, electric power, meteorology, computer room, oil field, mechanical and electrical installation and maintenance and uses electric power as industrial power or the business department of the commonly used power industry but essential instrument.
It is suitable for measuring the resistance of various insulating materials and the insulation resistance of transformers, motors, cables, and electrical equipment.
