The UT526 is a universal measuring and testing device for performing inspections of electrical appliances. It allows checking the equipment of circuit breakers, measuring the resistance of the earthing loop, measuring the insulation resistance, measuring the frequency of AC voltage and measuring DC and AC voltage. The device is newly designed in a durable housing with new analog, digital and microprocessor circuits. This device has been designed, manufactured and tested according to the safety standard IEC61010 (Safety requirements for electrical equipment) in the CATIII 600V overvoltage category. It fully complies with the ČSN EN 61557 standard for measuring insulation and transient resistance.
