4.10 Pick Rate Warning
This screen appears when the pickup rate warning function is used. This screen allows checking for a drop in
the component pickup rate on each component or head. Clicking the tab to switch the display.
The pickup rate is reset in real-time after mounting a group of components. However, if a particular component
or head is not used then its row will not appear on the display. Pickup rates can be monitored by color during
operation.

What is
"watch-and-wait" mode?
When "watch-and-wait" mode is entered by pressing the [Current Check] or [All Check] button, the abnormal pickup rate
at that point is stored and the color of "red" row(s) changes to "pink" temporarily. If the pickup rate then improves or
deteriorates from that point onward, the color of the row(s) changes to report the new state to the operator.
For example, after an abnormal pickup rate is stored in "watch-and-wait" mode, if the problem is eliminated and
operation resumed, and the pickup rate improves, then the color of the row(s) changes from "pink" to "yellow" to show
an improvement has been made. Conversely, if the pickup rate becomes even worse, then the color changes from "pink"
back to "red" to show the troubleshooting was ineffective.
The colors in the following graph show changes in the pickup rate, using an example when "caution (yellow)" is set to
99.00% and "warning (red)" to 95.00%.

Reference
When "watch-and-wait" mode is enabled, the color of the "red" row(s) showing an abnormal pickup rate changes to
"pink" and the pickup rate at that point is stored. The "pink" color then changes according to changes in the pickup
rate from that point onward.
