Model 5030 SHARP Monitor Instruction Manual
Note To achieve the most accurate mass calibration, the T2 sample
temperature should be as stable as possible and therefore the instrument
should have the IMR heating system turned off, and the instrument should
be allowed to equilibrate to shelter or ambient temperature. If the Model
5030 SHARP 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.
To begin the mass calibration using the
reference mass foils, press YES.
Please enter the SPAN foil value using the +, -
keys. Press NEXT.
The beta attenuation chamber should now
open. During this period, this screen will be
displayed for approximately thirty seconds.
Cut/break the filter tape on the left side of the
measurement head and pull the remaining filter
tape out from the right hand side. Then insert
the foil holder from the left into open gap.
Maintaining a slight sideward pressure on the
filter holder, press NEXT to proceed with the
foil calibration, or press ABORT to stop the foil
calibration.
While the beta attenuation closes, this screen
will display for approximately thirty seconds.
Insert the zero/null foil. Press NEXT to continue
or press ABORT to stop the foil calibration.
The auto zero procedure of mass will begin and
last for approximately 200 seconds.
