Selecting an Agent ID To select an Auto Agent ID: 1 2 3
Touch GAS. Touch SELECT AGENT. Touch AUTO ID.
You can manually choose an agent type by touching the SELECT AGENT key in the main menu which opens the agent selection sub-menu. The prompt line above the sub-menu identifies the detected agent: DES, SEV, ISO, HAL, ENF. MIX is displayed if more than one agent is detected, and NONE if the agent type is not identified.
To select Agent ID manually: 1 2 3
WARNING: • In the event an agent is selected manually, but not administered, the analyzer will detect the difference and begin flashing the detected agent’s label. This is to alert the clinician to possible errors.
Touch GAS. Touch SELECT AGENT. Select HAL, ENF, ISO, SEV, DES.
Touching the AUTO ID key sets the analyzer to automatically use the agent type detected. The five agent keys are the manual agent selection keys. Selecting one of the agent keys forces the analyzer to use and report the concentration levels based upon coefficient factors of the manually selected agent. In AUTO ID mode, if nonzero concentration levels are reported for more than two minutes and the agent type is not detected, the AUTO ID key flashes. If in manual mode and the selected agent type is different from the detected agent type, the key that is labeled with the detected agent flashes. The agent parameter label areas are flashed on all screens when a conflict is detected. A conflict is confirmed and the flashing stops when either a key is touched in the Select Agent menu or the Select Agent menu is exited. Conflict detection is restarted if: • •
the agent concentration level goes to zero for more than two minutes. an agent type is selected that is not the type currently selected and not the first agent type in conflict.
