Product Introduction

ETCR3460B Insulation Resistance Tester, also known as megohm meter, insulation resistance tester, which is used for insulation resistance testing.This instrument with LCD large screen with backlight display, data hold automatic discharge, automatic shutdown and other functions. The instrument has the functions of test timing and voltage monitoring. When the loop voltage is higher than 36v. the instrument will forbid tested to protect the safety of the tested objects and personnel. The instrument function is easy to operate, insulation resistance value, test time, output voltage display with the same screen. also have the functions of measuring AC voltage, DC voltage.
ETCR3460B Insulation Resistance Tester complete appliance 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, dust proof, moisture-proof structure, and it is suitable for applying to measuring the insulation resistance of electric motor, cable, switch, electrical appliance and other electrical equipment and insulation materials, which is the telecommunication, the electric power, the meteorology, the computer room, the oil field, the mechanical and electrical installation and the maintenance and uses the electric power as the industrial power or the energy industry enterprise department commonly used but essential instrument.
1.50V, 250V, 500V, 1000V, 2500V and 5000V 6 gears in total output voltage, wide measurement range 0.1MΩ~1000GΩ, max. short circuit current 2mA.
2.Insulation resistance value, test time, output voltage display with the same screen.
3.Safe structure and brand-new design of the improved circuit have more complete functions, higher accuracy, and more convenient and reliable operation.
4.Automatic discharge function, perfection protection circuit, effectively prevent damage to the counterattack voltage.
5.The host has large LCD display with white screen backlight display, bar chart indication, which is clear and obvious.
