Configuring Measuring-Module-Specific Settings
When using an out-of-setting-range current sensor
You can use an out-of-setting-range current sensor using the scaling function.
Refer to “Automatically saving waveform data” (p. 84).
1
Click the area that includes [Sensitivity] .
The setting dialog box appears.
2
Click [Sensitivity] box, and then enter sensor sensitivity.
Multiply the sensor sensitivity of a sensor to be used by a certain value to allow a product to fall within the
setting range (0.1 to 10), and enter the product.
3
Click [Close] .
The setting dialog box closes.
4
Click the [Scaling] box, and then configure the scaling setting.
Configure the scaling setting so that a scaling ratio is the same value as the number you multiplied the sensor
sensitivity by.
Example 1
For sensor sensitivity of 23.4 pC/(m/s
2
)
Specify 10 pC/(m/s
2
), which results from multiplying the sensor sensitivity by 1/2.34, as the sensor sensitivity.
To display measured values after multiplying them by 1/2.34, configure the scaling setting as follows:
To configure the scaling setting using the conversion ratio method
Ratio 0.4274E+00 (= 10/23.4)
Offset 0.0000E+00
Units m/s
2
To configure the scaling setting using the 2-point method
Input1 2.3400E+00 Scale1 1.0000E+00
Input2 0.0000E+00 Scale2 0.0000E+00
Units
m/s

Example 2
For sensor sensitivity of 0.05 pC/(m/s
2
)
Specify 0.1 pC/(m/s
2
), which results from multiplying the sensor sensitivity by two, as the sensor sensitivity.
To display measured values after multiplying them by two, configure the scaling setting as follows:
To configure the scaling setting using the conversion ratio method
Ratio 2.0000E+00 (= 0.1/0.05)
Offset 0.0000E+00
Units m/s
2
To configure the scaling setting using the 2-point method
Input1 0.0500E+00 Scale1 1.0000E+00
Input2 0.0000E+00 Scale2 0.0000E+00
