Screen Organization
MEASURE Screen Group
• INITIAL INTERVAL
In the INITIAL INTERVAL field, you set the
initial interval
which is the
interval of measurement trigger. Not measurement interval. Measurement unit
executes measurement if it is ready to measure at the trigger. If the unit is busy
or in measurement, the unit waits for the next trigger.
• NO. OF SAMPLES
This field sets the number of samples . The number of samples must be 10001
or less (total for all units that make measurements plus size of all registered user
variables). The number of units that make measurements is determined by the
DISPLAY: DISPLAY SETUP screen.
• TOTAL SAMP. TIME (for linear and thinned-out sampling mode)
TOTAL SAMP. TIME field sets the total sampling time . The total sampling
time must satisfy the following condition:
total sampling time
³
initial interval
´
( number of samples
-
1)
In this field, enter a value or select:
• NO LIMIT secondary softkey to continue the sampling until sampling
completion condition is satisfied. For linear sampling mode,
initial interval
must be more than 480
m
s.
• (for linear sampling mode only) AUTO secondary softkey to set the total
sampling time to
initial interval
´
( number of samples
-
1).
• HOLD TIME
HOLD TIME field sets the hold time . The unit waits this time after forcing the
specified constant value, then sampling starts.
Range: (for initial interval < 2 ms)
-
30ms to 655.35s with 100
m
s resolution.
(for initial interval
³
2 ms) 0 to 655.35s with 100
m
s resolution.
• FILTER This field specifies SMU filter to
ON
or
OFF
. If this field is set to
ON
,
overshoot is decreased, but settling time takes several ms. Be aware of this if
you set initial interval to a short time.
