3.7 Rough Tuning, Fine Tuning & Increment & Decrement Adjustment
of Load Current.
The maximum load current of 3260A Series High Power Electronic Load can be adjusted to
12.000A, 18.000A, 36.000A, 54.000A, 72.000A, 108.000A, 126.00A, and 80.00A respectively.
The relationship between the adjustment variation of the load current or resolution and
buttons is as shown in Table 3-11. During operation, when the time for depressing one of the
four buttons, e.g., rough tuning, fine tuning, increment and decrement, exceeds one second,
the resolution of load current adjustment shall change once per 10ms, e.g., the speed for
variation of load current will increase so that setting the load current can be completed in the
shortest period of time. Unless max. or min. value has been reached or depressing has been
interrupted.
