Calibration Procedures

Procedure Steps

1. 1 Gather required equipment: calibration standard, test gauge, fittings, and documentation
2. 2 Verify calibration standard is within certification period
3. 3 Connect test gauge to calibration standard using appropriate fittings
4. 4 Apply pressure in increments of 0%, 25%, 50%, 75%, and 100% of full scale
5. 5 Record readings at each increment on both ascending and descending cycles
6. 6 Calculate error percentage at each test point
7. 7 Verify readings are within acceptable tolerance (typically ±2% of full scale)
8. 8 Document results and apply calibration sticker with next due date

Procedure Steps

1. 1 Prepare calibration bath or dry-well calibrator
2. 2 Verify reference thermometer certification is current
3. 3 Insert test sensor and reference thermometer into calibration medium
4. 4 Allow sufficient stabilization time (minimum 10 minutes)
5. 5 Test at minimum three points across operating range
6. 6 Record sensor output and reference temperature at each point
7. 7 Calculate deviation and verify within specification
8. 8 Complete calibration certificate and update records

Procedure Steps

1. 1 Identify flow meter type and operating range
2. 2 Set up calibration rig with reference flow standard
3. 3 Ensure proper installation and orientation
4. 4 Run flow at 0%, 25%, 50%, 75%, and 100% of rated capacity
5. 5 Allow flow to stabilize at each test point
6. 6 Compare meter reading to reference standard
7. 7 Adjust meter if necessary and within adjustment capability
8. 8 Document calibration results and affix calibration label
