recording test tones on a hdr zoom 1608

[newengineer13]

I have heard that to get a good track while recording it is important to set the levels by using a test tone. I have been trying to find out how to do this for a week or so.

My gear: Zoom 1608 hdr with cd burner
Phonic mm1202 mixer
Senhieser es609 guitar cab mic
Sampson c01 condenser mic
Stageworks xlr dynamic mic
An Art pre-amp not sure of specs think i paid like 60 bucks for it.

If anyone can help that would be appreciated.
