AT520 AC Low ohm Meter (Battery Internal Resistance Meter)
AT520 is one kind of high precision and stability AC Resistance Meter. It can be used to test contact resistance, internal resistance and voltage of the battery. AT520 can be used to test the resistance and voltage of the battery simultaneously and make a comparation between them. Its quite suitable to be used in the battery produce line and factory checking and also the low resistance character of mechanical and electrical component, which request to be tested in low current condition. Compatible HIOKI3560 and Agilent4338B.
AT520 (the third edition [2011], test voltage has be extended to 100VDC)
