JOG to TRIP MODE
After performing the steps under BASIC OPERATION, follow the steps below to perform the Jog to Trip
function.
1. Click Settings in Test Parameters. Enter the number of cycles that the output will be energized.
This should be long enough to get a good reading and at least twice the expected instantaneous trip
time, but short enough to avoid overheating. Phenix Technologies recommends a value of 7 cycles.
Be sure to click OK to record the setting.
2. Click Settings in Test Parameters. Enter the time period that the regulator will increase its output
with the output of the test set de-energized. The OFF Seconds should be long enough to move the
Vernier a reasonable amount, such as 1 to 2 seconds, but not so long that the current increment is
too coarse. The setting of the Regulator Speed Control also must be adjusted in conjunction with
the OFF SECONDS to prevent too much / too little travel during the OFF time.
3. Click Settings in Test Parameters. Set the maximum current allowed on the output of the test set.
Factory setting / maximum setting is based on the 1 second rating of the specific model. If desired,
the MAXIMUM AMPS may be set to a lower value to limit the current if the breaker does not trip at
the expected value. Typically set at 20% higher than the expected trip current.
4. Ensure that the beaker status indicator indicates that the Breaker is CLOSED.
5. Click the START button to begin the test.
6. The test set will automatically increase the current until the breaker trips. Press the STOP button to
stop the test at any time.
Optional – click Save Results.
