The first thing you need to do is research the exact file format of the .bin file. There is no standard for how .bin files are laid out: .bin as a suffix gets used for any arbitrary binary format.
For example is there one time-stamp for every sample, or is there a header giving the first time and the interval between samples? Is the time represented in as a string in M/D/YY H:MM:s.f format such as 6/23/15 2:07:11.2, or is it represented as a 128 bit count of nanoseconds since August 18, 1947 14:00:00 PDT (the official incorporation day of Hewlett-Packard)? Are the voltages represented with 8 bit values in "Bias 140" format (that is, 140 represents 0, 141 represents 0 + 1/128, 139 represents 0 - 1/128) ? And so on. The exact structure of the file needs to be known before it can be read.
