Parameters:
L1: Set the loading value for A load.
L2: Set the loading value for B load.
I_LIMIT: Set the maximum current for loading.
RESPONSE: Set the Electronic Load response speed to FAST, NORMAL or SLOW.
I_RANGE: Set the current measurement range of Electronic Load. There are H, M and L for
selection.
The push button rotary and arrow keys can be used to change the selection and the numeric
keys can input the setting values.
Ranges (Low, Middle, High)
Voltage can be programmed in any of the three ranges, low range, middle range and high
range. The low range provides better resolution at low voltage 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 CV mode of Load is active, the new setting will change the
input immediately at a rate determined by the slew rate setting.
A/B State Switch
The static function has two setting levels L1 and L2. Use the
A/ B
key on the Load to
manually switch between the two programmed states. Slew rate determines the rate at
which Load level changes from one load level state to another.
CAUTION
It is suggested to use a remote sense cable to measure the UUT output
voltage.
Constant Power Mode 3.6.4
In CP mode, the Load will sink a current according to the programmed power. To enter into
the CP mode, press the
MODE
key and select CP mode.
