and reset signals have been actioned, otherwise the minimum timings below should be
observed.

Single Switch:
The start signal is permanently connected and the instrument is controlled by the reset input.
The reset input is fail-safe so the position shown is for the reset state. The switch needs to be
in the start position for the whole of the test. At the end of the test the switch may be returned
to the reset position. This method can not use the auto-reset or continue-on-start features.
