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 is the input current in amperes.

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.
