Setting Ripple Level

PROCESS → CONTROL → RIPPLE
This function lets you set the output ripple to either a low amplitude ripple (less than 2% rms)
or a high amplitude ripple (4 to 5% rms).
To set the RIPPLE mode, follow these steps:
1. Press PROCESS → CONTROL → RIPPLE
2. Rotate the MODIFY knob to select "low" or "high."
3. Press ENTER to accept and exit.

Using the Target Conditioning Cycle (TCC)

PROCESS → CONTROL → TCC
The TCC menu lets you enable the TCC (Target Conditioning Cycle) algorithm and set the
TCC "idle" timer. Enabling the TCC algorithm places setpoint and arc handling under
microprocessor control, letting you achieve fast, automated target conditioning. Before
enabling the TCC algorithm, ensure that you have first entered a setpoint and set values for the
arc handling parameters.
When TCC algorithm is enabled and the unit receives an on command, the microprocessor sets
the arc detect time to 20 μs (in "custom" arc handling, the shutdown time remains unchanged)
and initiates a series of trials (or "steps") to reach your desired setpoint ("the final setpoint").
To begin, the microprocessor sets an initial setpoint equal to 50% of the final setpoint. After
10 ms, the microprocessor checks the output level and sets a new interim setpoint equal to
125% of the output level. The microprocessor continues to check the output level and to set a
new interim setpoint (always 125% of the output level) every 10 ms until the output level is
equal to 80% of the final setpoint. When 80% of the final setpoint is reached, the interim
setpoint is set equal to the final setpoint, the TCC algorithm ends, and arc handling is returned
to the parameters you set up previously.

ENABLING TARGET CONDITIONING CYCLE (TCC)

PROCESS → CONTROL → TCC
This function enables or disables the TCC algorithm.
To enable TCC mode, follow these steps:
1. Press PROCESS → CONTROL → TCC → ENABLE.
2. Rotate the MODIFY knob to select Yes or No to enable or disable TCC mode.
3. Press ENTER to accept and exit.
