How To Switch Channels in the Main Display
The system defaults to showing the pressure reading for channel 1 in the main display. The
exception to this is if all four channels are used, whereupon the pressure reading for channel 4
appears in the main display. Channel 4 can only be monitored in the main display.
By following the procedure explained below, the pressure reading from any of the four channels
can be shown in the main display. Alternately, the main display can be configured for a dual
channel display.
The dual channel display feature of the 146 unit automatically switches between two user-
selected channels to provide a pressure readout in the main display. The dual channel display
can only be viewed in the main display. The channel numbers of the two user-selected channels
that make up the dual channel display are shown to the right of the main display. When
configured for dual channel display, the 146 unit can provide a pressure readout that shows
pressure readings over a larger dynamic range than when the main display shows only a single
channel’s pressure readout.
Two dual channel setups can be configured (Dual Channel 1, and Dual Channel 2). The same
channel can be used in both setups. For example, if Dual Channel 1 switches the main display
between channels 1 and 4, Dual Channel 2 can still be setup to switch between channels 3 and 4.
It does not matter that channel 4 is used in both setups, because only one setup can be used a
time.
Note
The Dual Channel feature only effects what is shown in the main display.
System control cannot be governed with two channels.
One of the two channels used in a Dual Channel display can be used for
control. Control does not switch to the other user-selected channel,
however, when the main display readout switches to the other channel.
1. Repeatedly press the [
DISPLAY MODE
] key until the 146 unit is in Normal Mode.
The system responds by scrolling through modes.
2. Press [1], [2], [3], or [4], (to select a channel), or press [
DUAL
][1] or [
DUAL
][2], (to select
dual channel display feature 1 or 2).
The system responds by showing the selected channel’s pressure reading, or changing to
dual channel display, in the main display.
For example, in Figure 25, page 101, channel 4 is shown in the main display. An
example of a dual channel display is shown in Figure 27, page 105.
