Navigating the Menu System
The menu system of the XTR follows a select and set model with the
exception of the VOL and CUR modes. See
“Setting VOL and CUR
Modes”.
The general procedure for setting up the features in the select and set
model is:
1. To select a mode, rotate the 9-position mode control knob to the
desired mode or press the Rotary knob/Enter button once to activate
the current selection on the mode control knob. See
Figure 3-2.
2. To select the feature or setting, rotate the Rotary knob/Enter button to
scroll through the different available settings of that mode.
The settings appear on the output current display.
3. Press the rotary knob/Enter button to select the feature or setting.
4. Set each value using the Rotary knob/Enter button. When the value
has been selected, press the Rotary knob/Enter button to commit the
updated value. Additional values may become available, depending
on the setting that is being configured.
Setting VOL and CUR Modes
The only exceptions to the select and set model are the VOL and CUR
modes which do not allow the selection of tracking and select and set
mode by rotating the Rotary knob/Enter button. In VOL and CUR modes,
the default entry mode setting is automatically selected as either voltage
or current tracking, respectively.
Voltage and current values can be set in tracking mode or select and set
mode using the Rotary knob/Enter button:
• Tracking mode—the new values take effect as the Rotary knob/Enter
button is rotated.
• Select and set mode—the new values do not take effect until the
Rotary knob/Enter button is pressed. See
“Normal Display Mode and
Inactivity Timeout” on page 3–6.
To access the tracking mode for entering voltage and current:
1. Select the VOL or CUR position on the mode control knob.
If the set point is blinking, the unit is in coarse tracking mode.
• When the VOL mode is selected, the voltage set point will blink in
the output voltage display.
