7.4.2 Event indication
Figure 20 Linear and dual slopes
The screen illustrated left shows the Linear mode.
As shown, an analog output will be activated on a
measurement. The lower end of the scale will be 0 mA on a
value of 1 ppm and the high end of the scale will be 20 mA on
a value of 12 ppm.
The difference in display between this Linear mode and the
Dual
mode, is that an extra field (MIDDLE) is required in
addition to the LOW and HIGH values.
Select the EVENT INDICATION option in the mA Outputs
menu to display the options available for event setting.
Select the option for which you want to set an event.
