Use the appropriate container for weighing liquids, powders, or granular substances. Start by placing the container on the pan and zeroing the balance. Then, carefully add the sample (either directly, or by removing the container and making sure the control bar is untouched), close the doors and check the readout.
    If any chemicals have spilled on the balance, it should be cleaned thoroughly. Shut it down (by gently raising the control bar) after you’re done using with your weighing procedures for the day.
These sensitive devices are easily affected by air currents, temperature and other physical variables, so they are enclosed or shielded to reduce exposure. Still, the enclosures will not be able to protect them completely.
