It won't help that much to try that with Raspbian since if you use any of the Linux images they're limited to fit on a 4GB or 8GB card so should have to expand the ext4 partition first. Better reformat using SD Formatter, check and then burn again.
And yes, armbianmonitor is just a shell script that can be used everywhere but needs some packages. But I don't know whether f3 for example is contained in raspberry.org repos (I only have a RPi 2 and don't let Raspbian run but Ubuntu since it's ARMv7 optimized -- so can't check)
