Adjust limits +
The maximum and minimum adjustment limits can be dened
here. These limits are always interfering, in local or remote
mode, i.e. unit is controlled by a PC.
Limits of the set value of voltage
U adj Default: 0V, U
nom
= {U
adj.min
} {U
adj.max
}
Whereas U
adj.min
= {0...U
adj.max
} and U
adj.max
= {U
adj.min
...U
nenn
}
You can dene the lower and upper limit of the adjustable
voltage here. Set values which exceed these limits are not
accepted, neither from the control panel nor from the remote
control via a PC (communication with interface cards).
Limits of the set value of current
I adj Default: 0A, I
nom
= {I
adj.min
} {I
adj.max
}
Whereas I
adj.min
= {0...I
adj.max
} and I
adj.max
= {I
adj.min
...I
nom
}

= {0Ω…20 * Ri
nom
}

of the maximum adjustable internal resistance. Set values which
exceed these limits are not accepted, neither from the control
panel nor from the remote control via a PC (communication
