Constant Monitoring of the Discharge Status
Constant Monitoring of the Discharge Status
A Realtime Energy Monitoring* function is provided to monitor the Discharge defect
discharge energy consumed between the counter electrode and the
sample. The discharge energy is accurately set and controlled, and
discharge defects due to the surface condition of the sample can be
instantly detected from the discharge energy. The accuracy is improved
by eliminating samples with defects from the measurement.

Supporting Diverse Metal Materials
Many metal materials can be analyzed over a wide range of optimal discharge conditions, such as high-energy discharge for
metals like steel with a high melting point, or low-energy discharge for metals like lead and zinc alloys with a low melting
point, through the use of a newly-developed discharge energy stabilizing excitation unit.
