I have been a relatively happy owner of a Chargemaster and tonight, I need to load 100 rounds for a match in the AM. I fill my hpooer with my powder, turn the Chargemaster on, watch the count down, and get a "W" on the left end of the readout, and a "7" on the right end with an arrow pointing to "Link". I turn the unit off, remove the scale from the powder thrower, give it a puff or two, reattach them, turn it back on, watch the count down, and the same. Anyone have any ideas? thanks, J
