LDAT?
Linear Equation Data Query
Input:
LDAT? <input>[term]
Format: a
<input>
Returned: <linear value>[term]
Format: ±nnnnnn
Remarks: Also see the RDGST? command.
LINEAR
Input Linear Equation Parameter Command
Input:
LINEAR <input>, <equation>, <varM value>, <X source>, <B source>,
<varB value>[term]
a,n,±nnnnnn,n,n,±nnnnnn
Format:
<input>
<equation>
<varM value> Specifies a value for m in the equation.
<X source >
<B source >
<varB value> Specifies a value for b in the equation if <B source> is 1.
Example: LINEAR A,1,1.0,1,3[term] – The linear data for Input A is calculated from the kelvin reading
of the input using the equation: y = 1.0 * x – SP1.

Specifies which input to query: A or B.
Specifies input to configure: A or B.
Specifies linear equation to use.
Valid entries: 1 = (y = mx + b), 2 = (y = m(x + b)).
Specifies input data to use. Valid entries: 1 = kelvin, 2 = Celsius,
3 = sensor units.
Specifies what to use for b in the equation. To use a setpoint, set its units to
the same type specified in <X source>. Valid entries: 1 = a value, 2 = +SP1,
3 = -SP1, 4 = +SP2, 5 = -SP2.
Specifies which input to query: A or B.
(Refer to command for description)
0 = Unlocked, 1 = Locked
