Does the weighing pan touch the breeze ring or anything? Is the weighing pan installed
correctly?
Is the RE-ZERO key pressed before placing a sample on the weighing pan?
Is the sample placed in the center of the weighing pan?
Has the balance been calibrated using the internal mass (one-touch calibration)?
Has the balance been warmed up for 30 minutes before weighing?
Sample and container
Has the sample absorbed or lost moisture due to the ambient conditions such as temperature
