Why doesn't my HI 3010 register all of the fill material on the scale? If a fill cycle is started, and for some reason weight is applied to the scale before the OK To Fill Signal is given, when the OK To Fill signal goes true the scale is zeroed even though Use Auto Zero is off. Consequently, discharge is over when the scale reaches its Auto Zero point.
For example, I have the scale calibrated for 0 - 100 lb. I press start and "Waiting On" is displayed. If during this time I add 50 lb to the scale, it will now read 50/50. I then apply the OK to Fill signal and the display reads 0/50. I then add 50 lb to the scale and it reads 50/100 and awaiting OK To discharge comes on. I remove 50 lb from the scale and it reads 0/50. There is still 50 lb on the scale.
