Setting the Test Conditions
Number of applied pulses settings
Sets the number of test pulses to be used in the tests and the number of degaussing pulse
applications to eliminate magnetic fields from the workpiece.
Reference: “4.3 Number of Applied Pulses” (p. 42)
PULSE NUM
(Number of test pulses
applied)
Sets the number of test pulses to be applied.
The test pulses are applied continuously for the number of times that
have been set respectively in each voltage step.
DEGAUSS
(Number of degaussing
pulses applied)
Sets the number of degaussing pulses to be applied.
Degaussing pulses are applied continuously for the number of times
set at the start of BDV testing. (Degaussing pulse waveforms are not
sampled or judged.)
PERIOD
(Pulse application interval)
Sets the pulse application interval if multiple degaussing pulses and test
pulses are to be applied.
When multiple pulses are applied, the pulse application interval operates
at or above the set time.
There can be up to 32 test voltage steps max. If the voltage rise width setting is small, the test will
end when 32 steps have been completed even if the max. application voltage has not been reached.
