Parameters:
L1: Set the loading value for A load.
L2: Set the loading value for B load.
SR↗: Set the current rise slew rate data.
SR↘: Set the current fall slew rate data.
Vrange: Set the voltage 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)
Power can be programmed in any of the three ranges, low range, middle range and high
range. The low range provides better resolution at low power 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 CP 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
manually switch between the two programmed states. Slew rate determines the rate at
which Load level changes from one load level state to another.
