To display the Scale parameters after you press the Scale key:
1. Press Next to display T2 (starting time). The default is 0.
2. Press Next again to display RIU1 (starting or low refractive index change). The
default is auto.
3. Press Next again to display RIU2 (ending or high refractive index change). The
default is auto.
By entering appropriate times and refractive index change numbers in the four scaling
parameter boxes, you can zoom in on one section of the current refractive index
change trace.
• For RIU1 and RIU2, press CE to reset to auto.
• T1 represents the left side of the trace, or ending time to be displayed
(default is –30).
• T2 represents the right side of the trace, or starting time (default is 0).
The following figure shows a 10-minute trace of continuous 200 µRIU peaks.
Figure 5–22: Scaled trace of continuous peaks with T1 changed to –10
The following figure shows a 5-minute scaled trace (or zoom) of the 10 minutes of
continuous injections. T1 is changed to –5.
Figure 5–23: Scaled trace for 5 minutes of continuous peaks with t1
changed to –5
As you modify the output using the Scale function, the Trace function continues to
display the detector output in real time.
