SCAL
Generate SoftCal™ Curve
Input:
SCAL <std>, <dest>, <SN>, <T1 value>, <U1 value>, <T2 value>, <U2 value>, [<T3
value>], [<U3 value>]
Returned:
Nothing
Remarks:
Generates a SoftCal curve (Paragraph 8.2).
NOTE:
Curves are not permanently updated in
the curve Flash until a
CRVSAV
command is issued. May take some time, use the
BUSY?
command to determine completion.
<std>
Specifies the standard curve to generate a SoftCal from. Valid entries:
1
-
20
.
<dest>
Specifies the user curve to store the SoftCal curve. Valid entries:
21
-
60
.
<SN>
Specifies the curve serial number. Limited to 10 characters.
<T1 value>
Specifies first temperature point.
<U1 value>
Specifies first sensor units point.
<T2 value>
Specifies second temperature point.
<U2 value>
Specifies second sensor units point.
<T3 value>
Specifies third temperature point.
<U3 value>
Specifies third sensor units point.
Example: SCAL 1, 21, 340000, 4.2, 1.6260, 77.32, 1.0205, 300.0, 0.5189[term] -
Generates a three-
point SoftCal curve from standard curve 1 and saves it in user curve 21.
SETP
Configure Control Loop Setpoint
Input:
SETP <loop>, <value>
Returned:
Nothing
Remarks:
Configures the control loop setpoint.
<loop>
Specifies which loop to configure.
<value>
The value for the setpoint (in whatever units the setpoint is using).
Example: SETP 1, 122.5[term] -
Control Loop 1 setpoint is now 122.5 (based on its units).
SETP?
Query Control Loop Setpoint
Input: SETP?
<loop>
Returned: <value>
. Format:
±
nnn.nnnE
±
n[term]
Remarks:
Returns the control loop setpoint. See the
SETP
command for parameter descriptions.
<loop>
specifies which loop to query.
SETTLE
Sets Loop1 Settle Parameters
Input:
SETTLE [<threshold>], [<time>]
Returned:
Nothing
Remarks:
Configures Loop 1 settle parameters. (Refer to description of Status Byte Register in
Paragraph 9.1.3.1).
<threshold>
Specifies the allowable band around the setpoint. Valid entries:
0.0
-
100.00
.
<time>
Specifies time in seconds the reading must stay within the band.
Valid
entries:
0
-
86400
.
Example: SETTLE 10.0, 10[term] -
The Control Loop 1 input readings must be within ±10 K of the
setpoint for 10 seconds before the Within Control Limit flag is set.
SETTLE?
Query Loop1 Settle Parameters
Input: SETTLE?
Returned: <threshold>, <time>
. Format:
nnn.nn,nnnnn[term]
Remarks:
Returns Control Loop 1 settle parameters. See the
SETTLE
command for parameter
descriptions.
