The slew rate error increases as the slew rate increases.
Selecting SLEW RATE from the main menu will give you two choices:
Voltage slew - adjust the voltage slew rate
Voltage default - restore the default voltage slew rate
Selecting VOLTAGE DEFAULT will return the slew rate to the default value of
1% rated voltage per 150us.
To set the slew rate:
The combination must not exceed 1%/30us. Though the software will attempt to
achieve higher slew rates, it is limited to this value by hardware constraints. The
power supply slew rate cannot be faster than the rise and fall times given in the
product specifications on page 228. Manufacturer's recommendation is to keep the
slew rate at or below the default value.
