You should measure the sample at room temperature and close the balance’s side shields while taking the reading.

Quick scoop: what to do (and what not to do)

To get the most accurate mass reading on a properly stabilized balance:

  • Measure the mass of the sample at room temperature so there are no temperature‑driven drifts or convection currents affecting the reading.
  • Close all side shields/draft shields on the balance during the reading to block air currents and small disturbances.
  • Do not lean on or touch the table or bench, as this can introduce vibrations and shift the reading.
  • Do not place the sample on the edge of the pan; keep it centered so the weight is distributed evenly.

A quick way to remember it: center the sample, let it reach room temperature, close the shields, then read the value without touching the table.
