ZSI breaker testing work sheet Digitrip 1150+

The following are the test settings used while programming the 1150+ Digitrip unit. If a parameter setting does not match the one required 

for testing, record it in the space provided, and then modify the setting to match the chart. After testing, remember to change your settings 

back to the states you record below.
