Pickup and Timing Test Selection windows
Here is where the tests get executed by the user using the blue Play buttons. This is similar to the blue
Play button in the manual test screen. There are two types of tests listed, Pickup and Timing. The

Automated Pickup Tests
This feature is used to do pickup tests on breakers equipped with solid-state Long Time, Short Time,
Instantaneous, and Ground Fault trip devices. With a breaker curve selected, the output current will start
automatically ramping when the Pickup blue play button is pressed or clicked on. For the LTD and STD
pickup tests the user will be instructed to press or click on the Simulate Contact button when the
appropriate breaker Pickup LED lights. The current will start at 80% of the Sensor Multiple Setting * the
Sensor Rating * Pickup Value. The current will continue to ramp up based upon the Pickup Ramp Rate
setting until the Simulator Button is pressed, or Max Current or Max time settings are reached. For
Instantaneous and Ground Fault pickup tests the output current will Pulse Ramp based upon the Pickup
Ramp Rate, Pulse On Duration, and Pulse Off Duration settings. The current will start Pulse Ramping at
80% of the Sensor Rating * Pickup Value. The output current will be the incremented value for the Pulse
On duration time, before going back to the prefault state. The output will then stay at the prefault value
for the Pulse Off time before progressing to the next increment level until the breaker operates, or Max
Current is reached.
3.5.2.16.2
Automated Timing Tests
For Long Time Delay elements the default test multiple is 3 times the Sensor Rating * Sensor Multiple *
Pickup. For Short Time Delay elements the default test multiple is 1.5 times the Sensor Rating * Sensor
Multiple * Pickup. To change the test multiple; press or click in the Multiple Window and enter the desired
value. Up to three test points can be performed and recorded. To see all three default multiples, press or
click on the
symbol in the Timing Window next to the Multiplier window. The default Multiples are 3, 5,
