the setting on your meter is a maximum for that setting. when its switched to the 2mH setting, if you try to measure something like a 4mH coil, it will read "overload," "OL," or just a 1 on the left with the rest left blank. The "multiplier" is the "mH" meaning all readings for that setting are in mH. so a reading of .289 means 0.289 mH. if you switch to, say, the 2 H mode (i doubt there is one that high, but just for example...) in the 2H mode, if it read .289, THEN you would read it as 0.289 H (no milli).
