Is the sample placed in the center of the weighing pan?
Has the balance been calibrated using an external mass?
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
and humidity?
Has the temperature of the container been allowed to equalize to the ambient temperature?
Refer to “3-2 During Use”.
