6.2.2 Touchpanel Switch Operations
6.2.2.1 Panels and Switches
The averaging converter uses touchpanel switches which can be operated by just
touching the panel display. The display viewed upon power up or during oxygen
concentration measurement varies depending on the number of channel cards installed in
an averaging converter. Data of 4 channels will be displayed if 1 to 4 channel cards are
installed. If more than 4 channel cards are installed, data of 8 channels will be displayed.
Even if the number of channel cards is 4 or less, data of 8 channels will be displayed if
an expansion power supply unit is mounted and a card is installed on any of channels
CH5 to CH8. The display “---” means a channel no card is installed in the channel. As
shown in upper left and right displays in Figure 6.4, data of multiple channels can be
viewed in a single screen, which is called a multi-channel display.
