*The maximum programmable voltage values for each range are 1% higher than the rated voltage and the maximum
programmable current values for each range are 3% higher than the rated current.
**Each output channel "wakes up" with current progra mmed to a small positive value. This permits the output channel ’s
output voltage to be programmed up without specifically programming the current. An output channel, in fact, cannot be
programmed to zero amps. If the output channel receives a command to go to zero amps, or any positive current below the
minimum programmable current, it will set itself to the minimum. Note that you can use the DCPON command to cause the
ouput channels to wake up with the current programmed to a small negative value. This prevents current overshoots at turn
on if the unit is operating in constant current mode.
