What's the usage of storing recorded measurements of multimeter and soldering iron station in computer?
A multimeter with USB readout can be useful when a large number repetitive measurements has to be made.  Computer readout helps save time and reduces a probability of a data entry error.


Create test documentation (semi)automatically for each unit under test (UUT, DUT) during quality control (QC).
Observe trends during QC, which may point to upcoming issues.
Collect data during routine maintenance.
Collect data during field research.


p.s. There are even calipers with computer readout.  I have used them for measuring lesions after RF tissue ablation.  Our study required several hundred measurements.
