Record Range...
Allows access to the quantitation record range menu option which allows the Y-Axis range to be set.
Y-Axis Max.
The highest absorbance or transmittance (depending on the measurement mode) that is displayed on
the calibration curve Y-Axis.
Y-Axis Min
The lowest absorbance or transmittance (depending on the measurement mode) that is displayed on
the calibration curve Y-Axis.
Auto Re-Scale
When auto re-scale is on, the instrument will automatically change the Y-Axis minimum and maximum
points to display the scan in it’s greatest resolution. If set to off, the Y-Axis will use the user set
maximum and minimum points.
Instrument Set-up...
Allows access to the instrument set-up menu.
Accessory Set-up...
Only displayed if an accessory is fitted.
Performing Measurements
This mode is only available when the instrument is fitted with the multi-position cell holder.
Instrument set up parameters should be checked and reset prior to performing calibration and
measurement.
Two to seven calibration standards should be loaded into the cell holder in positions 1 to 7. Cell holder
8 is reserved for zero absorbance calibration or for subsequent sample measurement.
The number of calibration standards to be used and their concentrations (using the cell holder positions
as identification) should be entered via the CALIBRATION STANDARDS... mode.
CALIBRATE should then be selected from the menu and the key pressed to confirm.
Once a successful calibration is completed the instrument is now ready for sample measurement.
Selecting a specific sample number in the cell holder can be made using the numeric keypad or by
pressing the 0 key and then using the up/down keys. Cell positions will be shown as a column down
the left hand side of the display area.
