事件后的情况不太重要，尤其是在记录模式B中，在这种情况下，简单地延长记录的持续时间。重要的是，在事后记录时，新的触发信号可以启动新的事件。然而，这意味着两个事件重叠
并非总是能够完全重建以下情况：两个事件（部分事件前数据在前一事件中）。
整个事件存储器作为环形寄存器运行。这意味着可以删除单个事件，以便为新事件腾出空间而不必删除其他。可以选择内存已满时遵循的步骤。记录中断，并且没有新事件发生记录或最旧的记录被重写，以便内存始终包含最新的事件。必须注意的是在该模式下，记录可以在传输到操作员站之前删除。即使记录的传输正在进行进程将被中断，以便为新记录腾出空间。应用程序干扰记录器数据、电流、电压和测量值函数变量可以传递回RE。216装置使用转换程序接口和测试集XS92a（参见接口操作说明CH-ES 86-11.53 E）。
有关通过IBB传输干扰数据的程序
，请参阅第9.3节。干扰记录器数据文件以二进制格式存储，并且只能使用WinEVE程序进行评估（参见WinEVE操作说明*BHT 450 045 D0000）或修订程序
（见第1MDU10024-EN版操作说明）。
测量的函数变量可能有值，但不能完全由评估软件复制。此类变量可以使用比例因子“MeasCale”来减少。这个评估软件可以忠实再现的最高数字为±16535。评估软件自动考虑比例因子。处理器容量：干扰记录器功能在同一中央控制系统上运行作为保护功能的处理单元（CPU）。处理器
干扰记录器功能所需的容量占总容量的百分比，并与信号为：
9个模拟信号和0个二进制信号的20%9个模拟信号和16个二进制信号的40%
The post-event circumstances are of less importance, especially
in recording mode B, in which case simply the duration of recording is extended. The essential thing is that during post-event
recording, a new trigger signal can initiate the recording of new
events. This, however, means that two events overlap and it may
not always be possible to fully reconstruct the circumstances of
both events (part of the pre-event data is in the preceding event).
The entire event memory operates as a ring register. This means
that a single event can be deleted to make room for a new one
without having to delete the others.
The procedure followed when the memory is full can be selected. Either recording is discontinued and no new events are
recorded, or the oldest records are overwritten so that the memory always contains the latest events. It must be noted that in
this mode, a record can be deleted before it has been transferred to an operator station. Even if transfer of a record is in
progress, it will be interrupted to make room for a new record.
Application programs
Disturbance recorder data, currents, voltages and measured
function variables can be transferred back to the RE. 216 device
using the conversion program INTERFAC and test set XS92a
(see INTERFAC Operating Instructions CH-ES 86-11.53 E).
Refer to Section 9.3 for the procedure for transferring disturbance data via the IBB.
Disturbance recorder data files are stored in a binary format and
can only be evaluated using the WinEVE program (see WinEVE
Operating Instructions *BHT 450 045 D0000) or REVAL program
(see REVAL Operating Instructions 1MDU10024-EN).
Measured function variables may have values which cannot be
entirely reproduced by the evaluation software. Such variables
can be reduced using the scaling factors ‘MeasScale’. The
highest number the evaluation software can reproduce faithfully
is ±16535. The evaluation software automatically takes account
of the scaling factors.Processor capacity:
The disturbance recorder function runs on the same central
processing unit (CPU) as the protection functions. The processor
capacity required by the disturbance recorder function as a percentage of the total capacity and in relation to the number of
signals is:
20% for 9 analogue and 0 binary signals
40% for 9 analogue and 16 binary signals
