CCD Mode
In CCD mode, the Load will sink a dynamic current according to the programmed current
and dynamic timing regardless of the input voltage. To enter into the CCD mode, press the
MODE
key and select CCD mode.

Parameters:
L1: Set the loading value for Load1.
L2: Set the loading value for Load2.
SR↗: Set the current rise slew rate data.
SR↘: Set the current fall slew rate data.
T1: Set the loading time for L1.
T2: Set the loading time for L2.
REPEAT: Set the number of time to repeat (0=infinite loop).
Vrange: Set the voltage measurement range of Electronic Load. There are H, M and L for
selection.
Ranges (Low, Middle, High)
Current can be programmed in any of the three ranges, low range, middle range and high
range. The low range provides better resolution at low current setting. If any value is over
the maximum of low range, you must select the middle range. When any value is over the
maximum of middle range, you must select the high range. To change the range, press the
RANGE
key few times until the VFD range indicator is active at you want to select. The mode
change will affect the Load, so will the change of range. Both of them will cause the input to
go through an off state. If the CCD mode of Load is active, the new setting will change the
input immediately at a rate determined by the slew rate setting.
