Why does my 2430 fail to Source High Energy Pulses using the Pulse Mode
on the 10A Range?

In the 10A range, the duty cycle is limited to 8% with a maximum pulse width of
2.5ms.

To achieve a duty cycle of 8% with the maximum allowable pulse width of 2.5
ms, the Pulse OFF Time should be set for no less than 28.75ms.

Duty cycle = Pulse On Time___________
Pulse On time + Pulse Off Time

Pulse Off time = (2.5ms / 0.08)
