Fluke 1507 Insulation Resistance Tester

It is a device used to measure the resistance of insulation in electrical systems. This measurement helps to ensure that electrical insulation is effective and that it can safely withstand electrical stress. Insulation resistance testers are crucial for preventive maintenance and safety in electrical installations.
The tester applies a high voltage (typically between 250V and 5kV) to the insulation between conductors or between a conductor and the ground.It measures the resistance of the insulation as the current flows through it.
The resistance value is displayed on a digital or analog meter. Some advanced models also provide additional diagnostic information.
