• Temperature based instruments calibrated by calibrated digital thermometer

• 4 readings are taken then difference is noted and their mean is worked out.

• Weighing Balance: calibrated weight of 1gm, 10mg and 100mg are used.

• 3 reading of balance are noted and correction factor is calculated and then mean is calculated.
