Set up Log Stress/Measure timing
To set timing for log stress/measure mode:
1. Select Log.
2. In First Stress Time, set the time in seconds that devices are stressed during the first cycle.
3. In Total Stress Time, set the total stress time for the subsite. This is the total amount of stress
time that will have passed when the last stress is complete.
4. In # of Stresses/Decade, set the total number of stresses in each decade. There is a maximum
of 10 per decade. There can be up to 128 for all decades combined.
5. If needed, enter the Stress/Measure Delay in seconds. This is the delay after each stress cycle.
It allows the device to reach equilibrium before the next measurement.
6. Select Enable Periodic Testing to specify uniform, periodic intervals at which to interrupt the
stress to perform tests. These are in addition to the stress times.
7. If Enable Periodic Testing is selected, set the Rate. The number of cycles that will be done with
these settings are shown in the Total Cycles with Periodic field.
Clarius uses the values you entered to calculate the cumulative stress times for the cycles. The times
are displayed in the Stress Times box in seconds.
