Answer Posted / gcs
1. First select the calibrating equipment
2. for ex: For RTD, select RTD circuit with zero and span adjustment potentiometers.
3. make the input quantity (temperature) to zero.
4. adjust the zero adjustment pot ntill the output of the RTD becomes zero.
5. make the input quantity to high (Ex.100 deg) and adjust the span pot till the output becomes 100.
6. Repeat steps 3 through 5 till there are no changes in zero and span pot.
7. now the instrument is calibrated.
