General Procedures for Setting Up Features
• To select a mode, rotate the 9-position Mode control to the desired mode.
• To select the feature or setting, turn the rotary Adjust/Enter control to scroll through the different available settings of that mode.
• The settings appear on the output display.
• Press the rotary Adjust/Enter control to select the feature or setting.
• Set each value using the rotary Adjust/Enter control. When the value has been selected, press the Adjust/Enter control to commit the
updated value.
Setting the Output Voltage and Current Limit Using Tracking Mode
To access the tracking mode where new values take effect as the rotary Adjust/Enter control is turned:
1. Select VOLTS or AMPS on the 9-position Mode control. The set point will blink and the unit will be in coarse tracking mode.
• When VOLTS mode is selected, the voltage set point will blink in the output voltage display.
• When AMPS mode is selected, the current set point will blink in the output current display.
2. Use the rotary Adjust/Enter control to adjust the set point.
3. Press the Adjust/Enter control to use fine adjust tracking mode. The set point blinks faster when the unit is in fine tracking mode.
4. Use the rotary Adjust/Enter control to fine tune the set point.
5. Once the set point has been selected, press the Adjust/Enter control to exit tracking.
