5.2.1 Direction Push-buttons
This group of 5 push-buttons is referred to in this manual as the
direction push-buttons.
▲ & ▼ have two uses: to increase & decrease numbers, respectively,
or to go to the Previous & Next Displays, respectively.
The number increase and decrease functions are used whenever
values, which can be changed manually, are displayed on screen,
for example, changing a parameter such as the length of sampling
tube.
The “Previous Display” and “Next Display” functions are used when
you want to view the previous or next screen texts. This can be
useful when setting up the monitor. By using these push-buttons,
you can scroll quickly through a branch of the Set-Up Tree. These
push-buttons can also be useful when viewing measurement data,
for example, if you are looking at gas A’s measurement result no.3
– by pressing ▲, gas A’s measurement result no.2 will be shown
on the screen. By pressing ▼, gas A’s measurement result no.4
will appear on the display screen.
◄ & ► enable you to move across number fields or go to the
Previous & Next gases, respectively.
When you are entering values or names in the monitor, for
example when setting up the monitor, you can use these push-
buttons to move the cursor across the entry fields.
“Previous Gas” & “Next Gas” functions are used primarily when
viewing measurement data. The display screen only displays the
measurement data for one gas at a time (out of 5 gases and water
vapour). These push-buttons allow you to look at the
measurement data for any one of the 4 other gases and water
vapour (see Fig.4.4 and section 4.3.9 ).
¿ Depending on the situation, this push-button acts as either an
“Enter” or “Go To Top of Measurements” function.
The “Enter” function is used whenever measurement units are
selected or any text, for example filter names or gas names, are
being entered. The Monitor display will typically display a text
similar to PRESS ENTER TO CHANGE VALUE.
The “Go To Top of Measurements” function is used in the following
situations:
