# SIS ECH Overview

This online manual explains:

IMS SIS Equipment Conditions Histories (ECH).

Condition History (full name is Equipment Condition History - ECH) is created from the [Schedule](/v414/docs/sis-schedules-overview) when the Schedule is to be executed. The ECH enables users to add one or more Tests assigned to the Schedule. Typically only one Test is assigned to a Schedule and to the ECH. If there is a [Checklist](/v414/docs/using-dynamic-forms) related to the Proof Test, then the Checklist can be used to guide the Proof Test and record the test findings.

Corrective actions ([Corrective Schedules](/v414/docs/defining-cairs)) can be created from the ECH. When the ECH is Approved, the related Schedule (if recurring) is credited and automatically a new Schedule with a new next due date is created.

SIS ECHs are aligned with the IMS ECHs as explained in [IMS Condition Histories (ECHs) across Discipline](/v414/docs/equipment-condition-history-ech).

By default only ECHs with the SIS related [Discipline](/v414/docs/ims-schedules-and-echs-across-discipline-1) (Instrumentation) will be shown in the [ECH Main Screen](/v414/docs/ech-main-screen). It is possible to use the filter to show ECHs from other Disciplines.

Take note that SIS ECHs can be [created](/v414/docs/step-a-creating-echs) on Equipment level. When creating an ECH in SIS it is automatically assigned to the SIS Discipline.
