注：時(shí)鐘采用24小時(shí)格式。
（3） 再次按下時(shí)鐘按鈕，然后所選頻道卡顯示將指示當前日、月和年。
注：1.日和月的顯示格式可為DD.MM或MM.DD，取決于系統的配置。
2.進(jìn)一步按下時(shí)鐘按鈕將在時(shí)間和日期之間切換顯示。
（4） 按下（）或（）按鈕或等待30秒退出時(shí)鐘模式。
4.8維護記錄打印輸出每個(gè)通道狀態(tài)的詳細打印輸出或可以使用工程卡啟動(dòng)整個(gè)機架。數據被饋送以ASCII文本格式發(fā)送到工程上的工程串行端口卡在前面板上。
要輸出每個(gè)通道卡的維護記錄，請按跟隨：
（1） 將RS232打印機插入工程卡串行端口。
（2） 按住所需的通道卡復位/選擇按鈕按鈕約1.5秒，直到出現所選圖標在頻道顯示器上。
（3） 同時(shí)按下向上（）和向下（）按鈕。選定的通道卡將顯示PRN，同時(shí)輸出以下數據：要輸出整個(gè)機架的摘要，請按以下步驟進(jìn)行：
（1） 將RS232打印機插入工程卡串行端口。
（2） 同時(shí)按下向上（）和向下（）按鈕，不使用任何按鈕
正在選擇通道卡，并將打印以下數據：
工程師的操作說(shuō)明涉及附加設施

Push the CLOCK push-button and the selected
channel card display will indicate the present time.
Note: The clock uses the 24 hour format.
(3) Push the CLOCK push-button a second time and the
selected channel card display will indicate the present
day, month and year.
Notes: 1. The display format for day and month can read
either DD.MM or MM.DD depending on the
configuration of the system.
2. Further pushes of the CLOCK push-button will
toggle the display between time and date.
(4) Push the ( ) or ( ) push-buttons or wait 30 seconds to exit the
CLOCK mode.
4.8 Maintenance Record Print Out
A detailed printout of the status for each channel or a summary of the
whole rack can be initiated using the Engineering Card. The data is fed
in ASCII text format to the engineering serial port on the Engineering
Card front panel.
To output the maintenance record for each channel card, proceed as
follows:
(1) Plug a RS232 printer into the Engineering card serial port.
(2) 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.
(3) Push the up ( ) and down ( ) buttons simultaneously. The selected
channel card will display PRN while outputting the following data:To output a summary of the whole rack, proceed as follows:
(1) Plug a RS232 printer into the Engineering Card serial port.
(2) Push the up ( ) and down ( ) buttons simultaneously without any
channel card being selected and the following data will be printed:
The engineer's operating instructions refer to the additional facilities
available to setup and maintain the system. Because the operation of the
system can be altered or impeded by these functions, they can only be
performed when the Engineering Card is unlocked by the Engineering
Key. ENGINEERING OPERATING ROUTINES
Depending upon the which keypad function push-button is operated, the
following engineering operating routines may be carried out:
Channel Reset.
Channel Select.
Channel Inhibit.
Alarm Configuration and Relay Test.
Catalytic Bridge Current Adjustment.
Zero Signal Calibration.
Span Signal Calibration.
1st Span Signal Calibration.
Sensor Signal Monitoring.
Clock/Calendar Adjustment.
Channel select and reset are carried out by the channel card RESET/
SELECT push-button. See Chapter 6, Section 3.
The remaining engineering functions are carried out after a control card
has been selected using the Engineering Card push-button controls.
