Plot Modes Window

When you're viewing an Individual Mode MTBF/FI/Reliability plot, you can select which of the failure modes in the current data sheet will appear by choosing Plot > Options > Plot Modes or by right-clicking the plot and choosing the option from the shortcut menu.

To show/hide all of the modes, click the column header above the check boxes. You can also select all modes of a given classification (i.e., all A modes, all BC modes or all BD modes) by choosing the desired classification in the Select by Mode field at the bottom of the window.

The order of failure modes in this window reflects the order of modes in the plot. By default, the modes are shown in the same order that they occurred during the observational period. To change the order, you can sort the modes by clicking the column header that you wish to sort by. Click the header again to reverse the order of the sort, and click it one more time to return the order to its original state.

• Classification displays the mode classifications.

• Mode displays the failure mode identifiers.

• Effectiveness Factor displays the corresponding effectiveness factor for each BD mode, if any factor was specified.

• Time to First Failure displays the first time at which the failure mode was observed.

• Before MTBF displays the mode's MTBF at the end of the observation period and before any delayed fixes are implemented.

• After MTBF displays the mode's MTBF after any delayed fixes are implemented. For BD modes, the "before" and "after" values will be different. For A and BC modes, they will be the same.

• Change in MTBF displays the difference between the "before" and "after" values for BD modes.
