2.3.2
Constant Voltage Mode (CV)
In CV mode, the load will attempt to sink enough current to control the source voltage to the programmed constant value regardless of
the change of input current. (see Figure 2.2). Press
key in basic mode to enter into mode selection and parameter setting menu.
Choose CV mode with

and
▼
cursor keys. Input the voltage setpoint value via the Entry keys or the knob with
◄

cursor keys.
Press
Enter
for confirmation.
The CV mode and parameters can also be set via remote command (MODE CV, VOLTage <NRf+>).

Setting Ranges
The setting range for voltage is 0 ... 80 V or 0 ... 200 V, depending on the model.
2.3.2.2
Immediate Voltage Level
The immediate voltage level refers to the voltage setpoint value in CV mode, which can be set via mode selection and parameter set-
ting menu, or via remote command (VOLTage <NRf+>). The immediate current level can also be modified directly with the

keys and the knob in CV mode.
2.3.2.3
Triggered Voltage Level
The triggered voltage level refers to the preset voltage value, which can become immediate voltage level automatically when a trigger is
received. If the CV mode and the input are enabled, the input will be updated immediately when a trigger occurs. If the CV mode is not
active, this voltage level will have no effect on the input until the CV mode is active. Once a voltage level is triggered, subsequent trig-
gers will become invalid until another (VOLTage:TRIGgered <NRf+>) command is received.
The trigger operation will be described in later chapter. The status register of the electronic load can keep track of pending triggers and
other operating conditions. which will be described in details in the “SPL SCPI Programming Guide”.
2.3.2.4
Transient Voltage Level
The load will switch between the transient high voltage level (LevelH) and transient low voltage level (LevelL) when the transient opera-
tion is enabled. The transient voltage level can be set in transient operation menu from the front panel, or via remote command
(VOLTage:HLEVel <NRf+>, VOLTage:LLEVel <NRf+>).
