量程信号校准
注：如果首次校准新传感器，请使用第1个第10节中的跨度程序。
要选择跨度操作，请按以下步骤进行：（1） 将工程钥匙插入工程卡前面板插座并检查解锁的LED（）是否点亮。（2） 按住所需的控制卡复位/选择按钮约1.5秒，并检查所选控制卡通过显示select（选择）来表示已选择偶像（3） 按下工程卡跨度按钮，然后所选控制卡将自动禁用，并且控件上将显示以下显示之一：
卡片信息显示：
a、 指示稳定的气体读数。
b、 A A表示气体读数上升。
c、 V V V表示气体读数下降。
注意安全
在配备2.4版软件的控制卡上，当零点抑制时
启用时，量距气浓度可显示为零（0）
直到施加量距气。在显示读数。
（4） 检查所选控制卡数字显示屏是否指示需要使用的量距气浓度，如果没有，则使用和
按下按钮以升高或降低指示，直到正确显示浓度。
注：1.模拟显示器将继续显示电流传感器现场信号电平。
2.在此阶段按下按钮将返回控制卡切换到选定模式，而不更改原始跨度
背景按照以下要求，以一定流速和时间施加量距气：
所选通道传感器说明手册。注：1.除氧气外，每个传感器应在被跨越。见第8节。
2.尽管量距气低至fsd值的15%可使用传感器，建议值为40%或更高。
（6） 当信息显示指示稳定时阅读，按下按钮。选定的控制卡将：陈列
在数字显示器上执行以下操作：
a、 将其量程校准参数调整为新显示的值值，前提是该值在配置的上限和下限范围内量程信号限值。
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.
