General information about AD-I400 Insulation Resistance Tester
This device can test insulation resistance(such as transformer,switchgear,lead,motor) of different modules in one system,to insulate and repair failure components. It is important to ensure products quality and security of person and equipments during operation by insulation test of checking test object to ground or adjacent conductors insulation.
Before power on the system,using insulation test to verify if it is good to improve system performance.Insulation test is to find manufacturing process problems and equipment fault which can not be found before failure happened.In EU,this test is compulsory,even to civil system.
Multi-channel test voltage,measurement insulation resistance up to 2TΩ.
31/2LCD digital show for insulation resistance value.
Auto switch range,easy to read.
Environment temperature measurement.
Auto-timing function,buzzer sound in every 15s.
R15S,R60S,R600S, absorptance,Polarization values auto measuring,calculating and saving.
Output short-circuit current more than 5mA,meet requirements of capacitive load fast charging.
Strong anti-interference ability,stable and reliable reading.
Complete protection function,ensure operation security.
Rechargeable Li-battery.Auto power off if low battery.
