the following steps should be considered.
1. Turn ON the digital scale
2. Zero the scale(this eliminate any previous measurements or default readings)
3. Place the dish on the scale and note the initial readings
4. Place the sample of NaCl to be measured and note the final reading
5. Subtract the initial reading from the final reading
The final reading is the amount of NaCl
