from 2A to 600A output
Contacts, bonding, battery straps,
graphite electrodes, motor windings,
and many more applications
Megger, the leader in low resistance testing, uses a Kelvin-
style test method to accurately take low resistance
readings. In order to take accurate readings, the potential
measurement is taken inside of the current injection
points. Therefore, either a current lead in tandem with a
separate potential lead or a “duplex” lead set is required. A
wide variety of lead sets is available and it may be possible
to design custom leads to suit special applications.
