4.4 Changing the Scale and Scrolling the
Display
There are three scales on the chromatogram display: X-axis [sec], Y-axis [mV], and temperature
[°C]. These scales can be changed to the desired ones using the commands in the [Scale] menu
or Enlarge/Reduce buttons.
n Disabling and Enabling the Auto-scale Function
In the Chromatogram window scales are automatically set to display an overall view of the
chromatogram. This function is called “auto-scale”.
TIP
Changing the scale automatically disables the auto-scale function.
This section explains how to enable/disable the auto-scale function.
l Procedure
(1) To disable the auto-scale, click on either the [Auto Scale] command in the [Scale] menu or
the Auto-scale button on the toolbar. This enables the auto-scale, causing the check mark (
) next to the [Auto Scale] command to disappear and the Autoscale button to appear not-
depressed.
(2) To enable the auto-scale, click again on either the [Auto Scale] command in the [Scale]
menu or the Auto-scale button on the toolbar. This enables the auto-scale function again,
causing the check mark (
) next to the [Auto Scale] command to appear and the Auto-scale
button to appear depressed.
n Changing the Scale
l Enlarge/Reduce Buttons
Each clicking on the Enlarge/Reduce buttons changes the scale as shown in the following table.
buttons: reduces the scale
buttons: enlarges the scale
Scale Available Scale Increments
X-axis scale (sec) 0.2→0.5→1→2→5→10→20→50→100→200→500→1000→
2000→5000→10000→20000→50000
Y-axis scale (mV) 0.1→0.2→0.5→1→2→5→10→20→50→100→200→500→1000
Temperature (°C) 10→50→100→200
The scales are common to both chromatograms and graphs of temperature data.
n Scrolling the Display
Scrolling the display to view the chromatogram not shown on the display, typically when the
entire chromatogram cannot t in the display because of, for example, scale enlargement.
The display can be scrolled using either of the following two methods.
l Method 1
Click on the , , , or button at either end of the scroll bars. The chromatogram scrolls in
the direction of the arrow by one increment of the scale with each click.
