6. Type the reference pressure values and the corresponding corrections. 

Calculate the corrections according to the following equation. You can also change the
settings on the left.

corr = P

reference 

- P

measured

The values are in hPa. The reference value is as whole number and the
correction with 2 decimals.

7. To save the corrections, select 

Write PTB210
