現(xiàn)在的如果工程關(guān)鍵是：安裝在工程卡上。報(bào)警按鈕當(dāng)操作報(bào)警按鈕時(shí)，所選的
控制卡提供該卡的級(jí)別和類型指示（上升或下降）的每個(gè)報(bào)警電平（A1、A2、A3、STEL、LTEL）。
如果工程鑰匙安裝在工程卡上，調(diào)整可以在預(yù)先定義的限制范圍內(nèi)達(dá)到報(bào)警水平，并且測(cè)試設(shè)施可用。該設(shè)施允許每次報(bào)警操作
待檢查，如果需要，其相關(guān)輸出繼電器應(yīng)：鍛煉。
3.3.9信號(hào)按鈕
當(dāng)操作信號(hào)按鈕時(shí)，所選控制卡提供該卡傳感器信號(hào)的指示：
跟隨：a、 4-20mA控制卡-回路電流（mA）。
b、 催化控制卡-催化橋輸出（靈敏度），單位為mV。
3.3.10歸零按鈕
零點(diǎn)按鈕只能在工程鍵處于以下狀態(tài)時(shí)使用：
安裝在工程卡上，用于校準(zhǔn)選定的控制卡。
3.3.11量程按鈕
只有在工程鍵為安裝在工程卡上，用于校準(zhǔn)選定的控制卡。
3.3.12第1跨按鈕第1跨按鈕只能在工程
鑰匙安裝在工程卡上，用于校準(zhǔn)量程安裝到選定催化控制裝置的新催化傳感器的點(diǎn)卡片
該功能用于提供指示，與隨后的正常量程調(diào)整，a的輸出靈敏度催化傳感器，并自動(dòng)指示中毒或損失傳感器性能。3.3.13時(shí)鐘按鈕
當(dāng)操作時(shí)鐘按鈕時(shí)，所選的控制卡提供機(jī)架的時(shí)間和日期指示時(shí)鐘
3.3.7 BEAD mA Push-button
When the BEAD mA push-button is operated, the display of the selected
Catalytic Control Card provides an indication of that card's sensor head
current.
Adjustments to this current can also be made if the Engineering Key is
fitted to the Engineering Card.ALARMS Push-button
When the ALARMS push-button is operated, the display of the selected
control card provides an indication of that card's level and type (rising
or falling) of each alarm level (A1, A2, A3, STEL, LTEL).
If the Engineering Key is fitted to the Engineering Card, adjustments
can be made to the alarm levels, within pre-defined limits, and additional
test facilities become available. This facility allows each alarm operation
to be checked and, if required, its associated output relay to be
exercised.
3.3.9 SIGNAL Push-button
When the SIGNAL push-button is operated, the display of the selected
control card provides an indication of that cards sensor signal as
follows:
a. 4 - 20mA Control Card - Loop current in mA.
b. Catalytic Control Card - Catalytic bridge output (sensitivity) in mV.
3.3.10 ZERO Push-button
The ZERO push-button can only be used when the Engineering Key is
fitted to the Engineering Card and is used to calibrate the zero point of
the selected control card.
3.3.11 SPAN Push-button
The SPAN push-button can only be used when the Engineering Key is
fitted to the Engineering Card and is used to calibrate the span point of
the selected control card.
3.3.12 1ST SPAN Push-button
The 1ST SPAN push-button can only be used when the Engineering
Key is fitted to the Engineering Card and is used to calibrate the span
point of a new catalytic sensor fitted to a selected catalytic control
card.
This function is used to provide an indication, in conjunction with
subsequent normal span adjustments, of the output sensitivity of a
catalytic sensor and to automatically indicate poisoning or loss of
sensor performance.
3.3.13 CLOCK Push-button
When the CLOCK push-button is operated, the display of the selected
control card provides an indication of the time and date of the rack
clock.
