All Pulses (ALL PULSE)
Measures the current in the number of
stages (1 to 20) specified by PULSE No.
As for measurement condition, the
condition number selected for
measurement start is used. The
judgment conditions are used
successively.
Ex.: In the case of three-stage current
flow with conditions 5, conditions 5 are
used as measurement conditions
whereas conditions 5, 6 and 7 are used
as judgment conditions respectively for
the first, second and third stages.
When you have selected “0” for PULSE
No, the instrument operates in the same
manner as when “1” is selected.
In All Pulses measurement,
multiple-stage current exceeding
maximum current measurement time
cannot be measured.
When CYC is selected for TIME, at least
1.0CYC of the current flow interval (time
that current does not flow) is required.
When ms is selected for TIME, at least
2ms of the interval is required.
If the number of measurement stages
are less than the number of stages
specified by PULSE No, the instrument
makes measurement for the maximum
current measurement time and the
pulsation error occurs. When the number
of measurement stages reaches the
number of stages specified by PULSE
No, the measurement ends.
Set all measurement conditions to use in
All Pulses measurement.
For example, when you have selected
“3” for PULSE No and started
measurement with conditions 3, set
measurement conditions 3 to 5. The
following settings are also needed to be
the same in conditions 3 to 5: TRIGGER,
MODE, CURRENT, TIME, CURRENT
RANGE, VOLTAGE RANGE in the
SETUP (1) screen, PULSE MODE,
PULSE No, COOL TIME, CURR FALL
LEVEL, CURR END LEVEL, MEAS
INHIBIT TIME, and MEAS MIN TIME in
the SETUP (2) screen.
When “2” is selected for PULSE No, the
instrument measures the current at the
first and second stages, and if conditions
3 are used for measurement start,
conditions 3 are used as measurement
conditions, and conditions 3 and 4 are
used as judgment conditions respectively
for the first and second stages.
