Applent Instrument’s AT526B AC Resistance Meter is designed on the principles of high accuracy and high precision. With a 32dgt ARM microprocessor, the AT526B comes equipped with an array of advanced features and functions like the comparator (sorting) function and the ability to detect damaged test wire. The meter utilizes the innovative vector test philosophy and voltage testing for precise analysis of open-circuit voltage and internal resistance.
The direct upgrade of the AT520, the AT526B is ideal for testing an expanse of contact resistance.
