3-32
IM 04L41B01-17E
Description • You can use this command on models with the
/M1 or /PM1 math option.
• Set parameters p1 and p2 by referring to the
table in section 3.3.
• You cannot use this command while
computation in progress.
• When using the /BT2 multi batch option, you
cannot use this command if any of the batch
groups is recording (memory sampling).
• About p3
Because the DX integrates sampled data
over each scan interval, the physical value
integrated over a given unit of time may be
different from the actual integrated value.
This occurs if the unit of time is different from
the scan interval. If this occurs, set p3 to the
same unit of time as that for the physical value
that you are measuring. The DX calculates
the integrated value using one the following
conversion formulas based on p3.
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 scan interval unit is seconds.
TX Sets the ancillary operation of
the start key
Syntax TX p1
p1 Computation operation (OFF, START,
RESET+START)
Query TX?
Example Configure the start key so that computation also
starts when the start key is pressed.
TXSTART
BH Sets a batch text field
Syntax BH p1,p2,p3,p4
p1 Batch group number
Set this parameter to 1 when multi batch
/BT2 is not in use
p2 Field number (1 to 24)
p3 Field title (up to 20 characters)
p4 Field string (up to 30 characters)
Query BH[p1,[p2]]?
Example Register the title “OPERATOR” and the string
“DAQSTATION” to batch group 1’s field number
2.
BH1,2,OPERATOR,DAQSTATION
Description • If you are using the /BT2 multi batch option,
you cannot use this command on a batch
group that is recording (memory sampling).
• For the characters that you can use, see
appendix 3.
• Set p1 by referring to the table in section 3.3.
EH Sets calibration correction
When p2 is set to BEGIN
Syntax EH p1,p2,p3
p1 Measurement channel number
p2 Type of operation (BEGIN)
p3 Number of break points of the calibration
segment (OFF, 2 to 16)
OFF
Turns off calibration
2 to 16 Number of break points
When p2 is set to SET
Syntax EH p1,p2,p3,p4,p5
p1 Measurement channel number
p2 Type of operation (SET)
p3 A specific break point (1 to 16)
p4 Input value of the specific break point
p5 Output value of the specific break point
Description • Set p1 by referring to the table in section 3.3.
• The selectable range for p4 and p5 varies
depending on the currently specified range.
• When the measurement range is set to scale,
the selectable range for p4 and p5 is -30000
to 30000.
• Set input value p4 so that the value increases
as break point p3 increases.
When p2 is set to END
Syntax EH p1,p2
p1 Measurement channel number
p2 Type of operation (END)
Example Set three break points for CH2.
EH002,BEGIN,3
EH002,SET,1,0,1
EH002,SET,2,50,49
EH002,SET,3,100,101
EH002,END
Description • First, use this command with p2 set to BEGIN
to specify the number of break points.
• Then, use this command with p2 set to SET to
specify the value of each break point.
• Finally, use this command with p2 set to END
to finalize the settings.
• The command “EH2?” causes the DX to return
the CH2 settings.
• The DX returns the settings in the format
shown in the above example.
• You cannot use this command when
computation is in progress.
BD Sets an alarm delay
On DXs without the /AS1 Advanced Security
Option
Syntax BD p1,p2
p1 Measurement, computation, or external
input channel number
p2 Alarm delay (1 to 3600)
