（2） 使用工程卡按鈕選擇所需的頻道。
（3） 按下BEAD mA按鈕，選擇通道卡顯示將指示配置的網橋現在的例如，200mA與所選通道交替數字
（4） 按下拒絕按鈕或等待30秒退出Bead mA模式。
4.5查看報警級別設置報警按鈕的操作允許查看每個報警集的報警閾值和報警類型（上升或下降）點A1、A2和A3。
Channel Select
Once a card has been selected, a particular channel can then be selected by using the ( ) and ( ) push-buttons on the Engineering Card. The selected channel number will be shown on the message display. 3.5 Deselect 3.5.1 Card Deselect To deselect a selected channel card, briefly push its front panel RESET/ SELECT push-button. The channel card will be deselected and any user operations in progress which have not been confirmed will be cancelled. It should be noted that the channel card will not be reset unless the RESET/SELECT pushbutton is again momentarily pushed. 3.5.2 Card Deselect with Channel Display Lock If the control card has been configured for a sequential channel display mode, it is possible to lock the display to a particular channel by deselecting the card using the push-button. To lock the display to a particular channel: (1) Select the required channel as indicated in Section 3.4.2. (2) Briefly press the push-button and the select icon will clear. The channel display will remain locked to the desired channel until the card is next reset or selected. 4. ENGINEERING CARD 4.1 General The Engineering Card push-button functions will only operate if a channel card is selected. See Section 3.3. Without the Engineering Key fitted to the Engineering Card, the following Engineering Card push-buttons will not be available: Inhibit Zero Span 1st Span If any of these push-buttons are pushed, a locked symbol ( ) will be briefly displayed on the selected channel card message display.
Bargraph Display
When operating the Engineering Card without an Engineering Key fitted, the selected channel's bargraph display will continue to indicate the actual gas reading during the operation of the available Engineering Card functions. 4.4 Catalytic Sensor Bridge Current The operation associated with the BEAD mA push-button only applies to catalytic channel cards. Operating this push-button with other types of channel cards selected has no effect and the warning message (XXXX) is displayed for a short time. To enter the catalytic sensor bridge current operation, proceed as follows: (1) Push and hold the required channel card RESET/ SELECT push-button for approximately 1.5 seconds until the selected icon appears on the channel display. (2) Use the Engineering Card ( ) and ( ) push-buttons to select the required channel. (3) Push the BEAD mA push-button and the selected channel card display will indicate the configured bridge current. eg. 200mA alternating with the selected channel number. (4) Push the reject ( ) push-button or wait 30 seconds to exit the Bead mA mode. 4.5 View Alarm Level Settings The operation of the ALARMS push-button allows the viewing of the alarm threshold point and alarm type (rising or falling) for each alarm set point A1, A2 and A3.
