MAIN Screen Overview
The 90XL screen that displays all real-time measurement information is called the MAIN screen.
The MAIN screen can display up to 4 channels of information based on the number and types of
sensor modules that are connected. The readings from all sensor modules are displayed
simultaneously on the one MAIN screen. If you are viewing multiple channels, there may be a
need to select a particular channel for further actions. This may be done by pressing the key
labeled
. This will scroll the selection indicator ( ) down one channel for every press of the
key. The scrolling sequence is “CH 1 through CH 4, then back to CH 1…, etc.” Unused channels
on the display are ignored during the scrolling function.
The SWAP function on the MAIN screen is used to swap the dominant and subordinate readings
within a conductivity and temperature channel. Simply select the channel you would like to
change using the
key, and press SWAP. (See Figure 1 below)
Fig. 1
The SWAP key has no affect for a single parameter channel.
