Numeric and cursor buttons
All parameters are adjusted using the cursor or numeric buttons. When using the cursors, the
adjusted digit in the center display will flash. When using direct numerical entry, press the number
and decimal point buttons until the desired value appears on the center display. Note that the current
is specified in mA.
The cursor buttons are used to adjust parameters:
• Up arrow increments the digit
• Down arrow decrements the digit
• Left arrow cursor selects and moves the digit to the left
• Right arrow cursor selects and moves the digit to the right
Select, Enter, Clear
To adjust a value, press the SELECT button until the appropriate LED is lit (for example, the
VOLTAGE LEDs SET or LIMIT). While the value is changing, the appropriate LED will flash indicating
that the value in the center display is not the present unit setting. If an incorrect value is entered,
press CLR (clear) to start over. When the desired value is in the center display, press the ENTER
button to update the unit's actual setting, and the LED will stop flashing.
