NITIALIZATION
When the electronic load is first turned power on, it wakes up with the input state set
OFF. The following commands are given implicitly at power-on:
*RST
*CLS
*SRE 0
*ESE 0
*RST is a convenient way to program all parameters to a known state, which is stored in
profile location 0.

URRENT
All models have a programmable current function. The command to program the current
is:
CURRent
where
Maximum Current
The maximum input current that can be programmed can be queried with:
CURRent? MAX
Overcurrent Protection
The electronic load can also be programmed to turn off its input if the current protection
level is reached. This protection feature is implemented the following command:
CURRent:PROTection
CURRent:PROTection:STATe ON | OFF
Undercurrent Protection
The electronic load can also be programmed to turn off its input if its input current is
lower than the under-current protection level. This protection feature is implemented the
following command:
CURRent:PROTection:UNDer
CURRent:PROTection:UNDer:STATe ON | OFF
NOTE: Use CURRent:PROTection:DELay to prevent momentary current limit conditions
caused by programmed input changes from tripping the overcurrent protection or
undercurrent.
