Configuring the scaling of the U8554/LR8534 Strain Unit

Strain gage-type converter
You can use values on the Strain gage-type converter's inspection record to convert the converter's
output into physical quantities.
Two methods are available: using a calibration factor*
When an inspection record provides a calibration factor
Setting example
To display waveform data measured using a strain gauge converter having a calibration factor of
0.001442 G /1 × 10

*1: Some inspection reports may provide a calibration factor in two representations: the one in per one
microvolt per volt (/1 μV/V) and the other in per 1 multiplied by 10 to the −6th power strain (/1×10
In such a case, enter the quantity expressed in per 1 multiplied by 10 to the −6th power strain.
When an inspection record provides rated capacity and rated output
See "(When the scaling conversion method is set to [Rating])" (p. 6 0).
Strain gage
To convert values measured using strain gages into strain, determine the scaling conversion ratio
using the following corrections:
• Output correction based on strain gage configuration
• Correction based on Young's modulus and Poisson's ratio of an object under measurement
Also, make the following corrections as required:
• Wire-resistance correction
• Gage-ratio correction
See "11.2 Measuring Strain" (p. 3 74).
