7.4.2 Event indication
Figure 22 Linear and dual slopes
The screen illustrated left shows an analog output to be
activated on a measurement on channel 1. 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.
The illustration is for a 3-channel analyzer allowing an event
to be set for minimum flow rates on each channel.
Select the option for which you want to set an event.
