Calibration
The Calibration window provides controls for calibrating each bulb
associated with your instrument. You may need to log onto the system as
a Manager to access these security-protected calibration functions.
Use the bulb spin controls to display current constants and valid
check standard data available for calibration of each bulb.
Calibration constants are determined individually for each bulb. Data for
automatic calculation of tube calibration constants is derived from check
standards run using that tube.
For information regarding the miniPV Series calibration procedure, see
Chapter 3, Calibrating the miniPV Series.
The Calibration window options are described briefly below:
Date selection: The calibration program uses data from previously-run
standards to determine the calibration constants. To select the desired
standard data, use the No older than [x] days spin controls to set the
date parameters for the database search (if “ 1 ” is selected, only the
standards run in the past 24 hours will be used).
Bulb selection: Viscometer bulbs are numbered from the bottom to the
top of the viscometer tube. Use the spin controls to select the correct
bulb for calibration.
Data selection: Test data from standards run with the miniPV Series
within the specified Date parameter will be automatically displayed in the
list box.
To select and deselect the data from the sample runs to be used for the
calibration, press and hold the
C key and click on the samples to
highlight those you wish to include in calibration calculations.
NOTE Sample run data from at least two different standards for each bulb at
each calibration temperature must be available for calibration calculations
to be performed.
After you have selected the desired data, release the C key and click
Calculate new constants to update values for C and E.
