3.4.2 Horizontal Trend display
Entered from the Vertical Trend display by means of the down arrow key, or selected via the
'Goto View'
key, this display mode (figure 3.4.2a) is similar to the Vertical Trend display described in section 3.4.1 above, except
that the traces are produced horizontally rather than vertically.

Figure 3.4.2a Horizontal Trend Display
One of the channels is defined as being the 'current' or 'scale' channel and this is identified on the chart by its pen icon
being diamond shaped rather than triangular as for non-current channels. If a channel is included in the display group,
but its status is 'not good' for some reason, then its pen icon is hollow. Each channel in the display group becomes the
'current' channel, in turn, for approximately 10 seconds – i.e. the channels are cycled-through, starting with the lowest
numbered channel. Once the final channel in the group has been displayed for 10 seconds, the lowest numbered chan-
nel is returned to and the sequence repeats. This scrolling process can be stopped using the Channel Cycling key in
the Option menu.
There are two faceplates associated with this display mode, one above the 'chart', showing the current channel's de-
scriptor and its digital value; the other - to the right of the 'chart' - showing a bargraph representation of the current
channel's value, together with a scale showing the low and high range values for the channel. Touching either of these
faceplates* causes the current channel number to increment. To select a particular channel to be the current channel,
the relevant pen icon can be touched. In either case, the bargraph and the background colour of the channel descriptor
take the colour of the new current channel.
There is no horizontal trend history function. Touching the trace for a few seconds, or using the Option key then 'En-
ter History' calls the Vertical trend history page described in
Time and date are printed on the 'chart' immediately to the right of grid lines, and it is to these grid lines that the
printed time and date relate.
*Note For zoned channels, the bargraph must be touched within the scale area.
