Calibration Procedure
Thermo Fisher Scientific Model 5030 i SHARP Instruction Manual 4-9
Note To achieve the most accurate mass calibration, the flow temperature
should be as stable as possible and therefore the instrument should have the
heating system turned off, and the instrument should be allowed to
equilibrate to shelter or ambient temperature. If the Model 5030
i Beta is
mounted within an ambient shelter, then the most stable time of day to
perform a mass calibration would be either early morning or late
afternoon.
▲
The preferred method of mass coefficient calibration is the Auto Mode.

In the Main Menu, choose Service > Mass Calibration > Mass

The Auto Mass Coefficient screen allows the user to conduct a mass
calibration of the measurement head and will walk you through the
process.
Use the following procedure to conduct a mass calibration:
1. In the Main Menu, choose Service > Mass Calibration > Mass > Auto .
2. Enter the SPAN foil value (e.g., 1,328 μg) using the keypad and press
to save the foil value and to open the bench. The beta
attenuation chamber should now open.
