• Stopping the Computation
• Stopping the Computation Simultaneously with the Memory Sampling
1. Press STOP.
A confirmation dialog box appears.
2. Select Mem+Math and press DISP/ENTER.
The memory sampling and computation stop, and the computation icon in the status display
section disappears.
• Stopping Only the Computation
1. In the operation mode, press FUNC.
The FUNC key menu appears.
2. Press the Math stop soft key.
The computation stops, and the computation icon in the status display section disappears.
Note
When the computation is stopped, the computed data of the computation channel is held at the
value that existed immediately before the computation is stopped. When memory sampling is in
progress, the held value is recorded.
• Resetting the Computed Results on All Computation Channels
This operation can be carried out when the computation is stopped. You can carry out this
operation even while the computation is in progress on DXs with release number 2 or later.
1. In the operation mode, press FUNC.
The FUNC key menu appears.
2. Press the Math reset soft key.
The computed results of all computation channels are reset.
• Releasing the Computation Data Dropout Display
This operation can be carried out when a computation data dropout occurs. When a
computation data dropout occurs, the computation icon turns yellow.
1. In the operation mode, press FUNC.
The FUNC key menu appears.
2. Press the Math ACK soft key.
The computation icon returns to white.
* Math ACK is displayed in the FUNC key menu only when a computation data dropout
occurs.
Note
A computation data dropout occurs when the computation process cannot be completed within
the scan interval. If computation data dropout occurs frequently, lessen the load on the CPU by
reducing the number of computation channels or setting a longer scan interval. If a computation
data dropout occurs during memory sampling, the data immediately before the dropout is
recorded as the computed data of the scan interval in which the dropout occurred.
