RAMP TIME FACTOR – Sets the rate of change for the output current. If the Ramp Time Factor is x1, the ramp
time will match the ramp time settings. If it is set to 1/10, the ramp time will be 1/10 of the ramp time setting.
RAMP UP/DOWN TIME - Sets the rate of change for Output current.
For RP1, the output current increases from Minimum to Maximum.
For RP2, the output current is initially set to the Minimum.

MIN OUTPUT - Sets the minimum output current (milliamps, amps for -12A,-25A). The value in the brackets is the
present output current.
MAX OUTPUT - Sets the maximum output current (milliamps, amps for -12A,-25A). The value in the brackets is the
present output current.
DITHER FREQ. – Options: 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, (Select OFF for 1000Hz).
