5.5.1 When to calibrate
The transmitter is factory calibrated and does not normally need to be calibrated in the field. Calibrate
the transmitter only if you must do so to meet regulatory requirements. Micro Motion recommends
using meter factors, rather than calibration, to adjust the meter to specific conditions. Before
calibrating, contact Micro Motion customer service.
5.5.2 Density calibration
Density calibration includes the following calibration points:
• All sensors:
- D1 calibration (low-density)
- D2 calibration (high-density)
• T-Series sensors only:
- D3 calibration (optional)
- D4 calibration (optional)
