Adding a DMM to a notebook PC is certainly handy for taking and recording measurements in the field. The card measures DC voltage and current, AC voltage and current, resistance, and diode voltage. What the probes lack, however, are clips to hold the probes to your circuit. I tested the card with a Fluke 5720A calibrator. In all ranges, the DMM card functioned well within published specs.
Saving is handy for sending the card into the field with a technician.
The technician can simply load the setup file and begin measuring. You can carry that one step further because the DMM card works with software drivers, so you can write a custom application. I also like the datalogging ability. Virtual Bench stores data in tab-delimited text files for easy import to a spreadsheet. The software also time-stamps each measurement.
