Use the DSM-8542 to Enhance Electronic Component
Automated Production Lines
DSM-8542 (Four-Channel) Application Examples
■ High-Speed Measurement of Capacitors by Charging with the Charge Terminal
● Twenty channels are used to charge (with current limiting) in parallel
using the same voltage as used for measurement.
Each terminal is independently current limited.
DSM-8542

■ Evaluate of Insulating Materials by Four-Point Simultaneous
High-Speed Measurement

● For reliability testing of insulation deterioration due to migration
of metallic ions in printed circuit boards, measurements are taken
simultaneously on four channels, and short intermittent peak current is
detected by high-speed measurement (repeated maxima).

* Each capacitor is charged for the specified time before connection to a
measurement terminal for leakage current measurement.
* Because there are 20 charging channels and four measurement
channels, the time required for charging prior to leakage current
measurement can be shorted to one fifth of the time required when
using measurement terminals only, increasing measurement throughput
by a factor of five.
