2.3.1.2 Immediate Current Level
The immediate current level refers to the current set value in CC mode, which can be
programmed
via mode selection and parameter setting menu, or via remote command (CRRRent
<NRf+>). The immediate current level can also be modified directly with left/right keys (
)
and the knob.
2.3.1.3 Triggered Current Level
The triggered current level refers to the preset current value, which can become immediate
current level automatically when a trigger is received. If the CC mode and the input are enabled, the
input will be updated immediately when a trigger occurs. If the CC mode is not active, this current
level will have no effect on the input until the CC mode becomes active.
The triggered current level only can be set via remote command (CURRent:TRIGgered <NRf+>).
Once a current level is triggered, subsequent triggers will become invalid until another
(CURRent: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 “ARRAY 372x Series Electronic Load
SCPI Programming Guide”.
2.3.1.4 Transient Current Level
The load will switch between the transient high current level (LevelH) and transient low current
level (LevelL) when the transient operation is enabled. The transient current level can be set in
transient operation menu from the front panel, or via remote command (CURRent:HIGH <NRf+>,
CURRent:LOW <NRf+>).
2.3.1.5 Software Current Limit
The electronic load allows the user to set a current limit (the current range is the same as that in
CCH mode ) via remote command. The load will be turned off with beeping alarms if the current limit
is exceeded beyond a programmable time delay (0.001-60s). Please note that the software current limit
is in effect for any mode of operation. Remote commands are listed as follows:
CURRent:PROTection <NRf+>
CURRent:PROTection:DELay <NRf+>
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 Fig.2-2). Press
key in
basic mode to enter into mode selection and parameter setting menu. Choose CV mode with
and
keys. Input the voltage value via the Entry keys or the knob with
and
keys. Use
key for confirmation. The CV mode and parameters can also be set via remote command
(MODE CV, VOLTage <NRf+>).
