5.16 Using the Linear Scaling Function for the Strain
(For Strain Module)
Function
Linear Scaling
Selecting the linear scaling method : Linear Scaling
• Select the linear scaling method from the following.
•
OFF
No linear scaling is performed.
•
Ax+B
The setting range and the initial setting of the scaling coefficient A and offset value B are
the same as described in section 5.10 “Using the Linear Scaling Function.”
•
P1–P2
Arbitrary scale values (P1:Y, P2:Y) are set against two arbitrary measurement values
(P1:X, P2:X). The scale converting equation (y=ax+b) is determined from these four
values.
• Measurement value (P1:X, P2:X) range : Same as the measurement range (see
section 15.22).
• Scale value (P1:Y, P2:Y) range
: –1.0000E+30 to +1.0000E+30
• Initial setting of scale values
: P1:X 0.0uSTR, P1:Y +0.0000E+00
: P2:X 1.0uSTR, P2:Y +1.0000E+00

Reading in the measurement values : Get Measure
When “
P1–P2
” is selected for the linear scaling method, you can read in the waveform
data into P1:X and P2:X while the waveform acquisition is started.
• During roll mode display
The data when the “Get Measure” soft key is pressed are read in.
• During update mode (not roll mode)
The last data of the displayed waveform when the “Get Measure” soft key is pressed
are read in.
Setting the unit : Unit
The unit setting is the same as described in section 5.10 “Using the Linear Scaling Function.”
