量程信號校準
注：如果首次校準新傳感器，請使用第1個(gè)第10節中的跨度程序。
要選擇跨度操作，請按以下步驟進(jìn)行：（1） 將工程鑰匙插入工程卡前面板插座并檢查解鎖的LED（）是否點(diǎn)亮。（2） 按住所需的控制卡復位/選擇按鈕約1.5秒，并檢查所選控制卡通過(guò)顯示select（選擇）來(lái)表示已選擇偶像（3） 按下工程卡跨度按鈕，然后所選控制卡將自動(dòng)禁用，并且控件上將顯示以下顯示之一：
卡片信息顯示：
a、 指示穩定的氣體讀數。
b、 A A表示氣體讀數上升。
c、 V V V表示氣體讀數下降。
注意安全
在配備2.4版軟件的控制卡上，當零點(diǎn)抑制時(shí)
啟用時(shí)，量距氣濃度可顯示為零（0）
直到施加量距氣。在顯示讀數。
（4） 檢查所選控制卡數字顯示屏是否指示需要使用的量距氣濃度，如果沒(méi)有，則使用和
按下按鈕以升高或降低指示，直到正確顯示濃度。
注：1.模擬顯示器將繼續顯示電流傳感器現場(chǎng)信號電平。
2.在此階段按下按鈕將返回控制卡切換到選定模式，而不更改原始跨度
背景按照以下要求，以一定流速和時(shí)間施加量距氣：
所選通道傳感器說(shuō)明手冊。注：1.除氧氣外，每個(gè)傳感器應在被跨越。見(jiàn)第8節。
2.盡管量距氣低至fsd值的15%可使用傳感器，建議值為40%或更高。
（6） 當信息顯示指示穩定時(shí)閱讀，按下按鈕。選定的控制卡將：陳列
在數字顯示器上執行以下操作：
a、 將其量程校準參數調整為新顯示的值值，前提是該值在配置的上限和下限范圍內量程信號限值。
SPAN SIGNAL CALIBRATION
Note: If a new sensor is being calibrated for the first time, use the 1st
Span procedure in Section 10.
To select the span operation, proceed as follows:
(1) Plug the Engineering Key into the Engineering Card front panel
socket and check that the Unlocked LED ( ) is illuminated.
(2) Push and hold the required control card RESET/SELECT pushbutton for approximately 1.5 seconds and check that the selected
control card indicates it has been selected by displaying the select
icon.
(3) Push the Engineering Card SPAN push-button and the
selected control card will automatically be inhibited and
one of the following displays will be shown on the control
card message display:
a. Indicates a stable gas reading.
b. A A A A Indicates a rising gas reading.
c. V V V V Indicates a falling gas reading.
CAUTION
On Control Cards fitted with version 2.4 software, when zero suppression
is enabled the span gas concentration may be displayed as zero (0)
until the span gas is applied. No adjustment sould be made until a
reading is shown.
(4) Check that the selected control card digital display indicates the
required span gas concentration to be used, if not, use the and
push-buttons to raise or lower the indication until the correct
concentration is displayed.
Note: 1. The analogue display will continue to show the current sensor
live signal level.
2. Pushing the button at this stage will return the control card
to the selected mode without any changes to the original span
setting.Apply the span gas at a flow rate and for a time according to the
selected channels sensor instruction manual.
Notes: 1. Apart from oxygen, every sensor should be zeroed before
being spanned. See Section 8.
2. Although a Span Gas as low as 15% of the fsd value of the
sensor may be used, it is recommended that a value of 40%
or above is used.
(6) When the message display shows to indicate a stable
reading, push the push -button. The selected control card will then
display
on the digital display while it carries out the following:
a. Adjusts its span calibration parameter to the new displayed
value, providing this is within the configured upper and lower
span signal limit values.
