When the bar tab is over $300 you can consider yourself well seasoned. And hopefully most of those sitting next to you also.
Most of the better moisture meters either have a provision for calibration to specific wood species or at least have a chart with the offset from the average reading for the different woods. Honey Locust being so dense, would definitely be on the upper end of the "deduct 10% or more" scale. If you want to try an interesting experiment, weigh what you think is a fairly wet split on a scale that will at least go to ounces or half ounces. Note the weight and what the moisture meter reads. Then take that split and force it dry either next to or under your stove or put it in the oven on 150˚ all day till it is absolutely dry. Check the weight and the moisture reading again. Baked dry, should read roughly 10-12%. This will give you the offset for that wood. Weight wise, put a jar on the scale and zero it and pour in water till you have the difference in weight, just to see how much water was actually in there. If you like algebra, you can do the math and see what the actual moisture content was. Did this once with a split that was delivered with two cords of "seasoned firewood" I bought and got over a quart of water out of just one average size split of Oak. Took three days to dry under the wood stove. Here is the info from Delmhorst. You can download it from here too. Not sure if it is specific to their meters or not. Species Correction Table
