6.5 Setting Commands (Measurement)
• This command cannot be specified while
measurement/computation is in progress or
while a report is being created.
SI Sets the rolling average of the
computation channel
When turning OFF the rolling average of the
computation channel
Syntax SI p1,p2
p1: Computation channel number (31 to 60) (31
to 42 on the CX1000)
p2: Rolling average ON/OFF (OFF)
Query SI[ p1]?
Example Turn OFF the rolling average of computation
channel number 31.
SI31,OFF
Description This command can be used on models with the
computation function option /M1.
When turning ON the rolling average of the
computation channel
Syntax SI p1,p2,p3,p4
p1: Computation channel number (31 to 60) (31
to 42 on the CX1000)
p2: Rolling average ON/OFF (ON)
p3: Sampling interval (1S, 2S, 3S, 4S, 5S, 6S,
10S, 12S, 15S, 20S, 30S, 1MIN, 2MIN,
3MIN, 4MIN, 5MIN, 6MIN, 10MIN, 12MIN,
15MIN, 20MIN, 30MIN, 1H)
p4: Number of samples (1 to 64)
Query SI[ p1]?
Example Turn the rolling average of computation channel
31 ON, set the sampling interval to 1 minute, and
the number of samples to 20.
SI31,ON,1MIN,20
Description This command can be used on models with the
computation function option /M1.
SJ Sets the TLOG timer
Syntax SJ p1,p2,p3
p1: Computation channel number (31 to 60) (31
to 42 on the CX1000)
p2: Timer (1 to 3)
p3: Conversion of the time unit for TLOG.SUM
computation
OFF No conversion
/S Convert as though the physical
values are integrated in units of
seconds.
/MIN Convert as though the physical
values are integrated in units of
minutes.
/H Convert as though the physical
values are integrated in units of
hours.
Query SJ[ p1]?
Example Set timer 1 to computation channel number 31.
No conversion of time unit.
SJ31,1,OFF
Description • This command can be used on models with
the computation function option /M1.
• This command cannot be specified while
computation is in progress.
• About p3
Because the sampled data are integrated over
each scan interval, the physical value
integrated over a given period may be
different from the actual integrated value.
This occurs if the given period is not equal to
the scan interval. In these cases, set p3 to
the unit of the integration time desired. The
integrated value is found according to the
following conversion equations that depend
on the parameter.
OFF Σ(Measured value)
/S Σ(Measured value) × scan interval
/MIN Σ(Measured value) × scan interval/60
/HOUR Σ(Measured value) × scan interval/
3600
The unit of the scan interval is seconds.
SS Sets the date and time at which
to switch the daylight savings
time
When the switching the daylight savings time is
OFF
Syntax SS p1,p2
p1
Summer time or winter time (SUMMER,
WINTER)
p2 Enable/disable (ON/OFF) the switching
(OFF)
Query SS[ p1]?
Example Set the summer time is OFF.
SSSUMMER,OFF
Description This command can be used on models with the
display language code “-2.”
When the switching the daylight savings time is
ON
Syntax SS p1,p2,p3
p1
Summer time or winter time (SUMMER,
WINTER)
p2 Enable/disable (ON/OFF) the switching
(ON)
p3 Date and time (yy/mm/dd hh fixed form.
Insert a space between dd and hh.)
yy Year (00 to 99)
mm Month (01 to 12)
dd Day (01 to 31)
hh Hour (00 to 23)
