(When the scaling conversion method is set to [Ratio] )
Enter the slope and the offset in [Slope] and [Offset] , respectively.
Select the numerical value entry item and press the ENTER key to display the numerical value
setting window.
See “Value entry method” (p. 7).
−9.9999e+09 to +9.9999e+09
Example setting
Make measurements using a strain* acceleration sensor with a calibration coefficient of
0.001442G /1 × 10 −6 and display waveform data as values expressed in units of gees
(G) (*: 10

Enter the post-conversion unit in [Unit] (up to 7 single-byte characters).
See “Text entry method” (p. 8).
5
(When the scaling conversion method is set to [2-point] )
Enter the pre- and post-conversion values in [Convert 1] and [Convert 2] , respectively.
Select the numerical value entry item and press the ENTER key to display the numerical value
setting window.
−9.9999e+29 to +9.9999e+29
Example setting
Convert 4-20 mA output from a sensor into 0 to 100 mm.
The 4-20 mA output is measured as 1 V to 5 V using a 250
Ω
shunt resistor.
Convert a range of 1 V to 5 V into that of 0 mm to 100 mm.
Unit mm
Convert 1 Convert 1 into 0 (1 V into 0 mm).
Convert 2 Convert 5 into 100 (5 V into 100 mm).
6
(When the scaling conversion method is set to [Sensitivity] )
Enter the sensitivity value in [Sensitivity] .
Select the numerical value entry item and press the ENTER key to display the numerical value
setting window.
−1.0000e+09 to +1.0000e+09
Example setting
Make measurements using a heat flow sensor with a sensitivity constant of 0.02421 mV/W•m
