Hard Keys and Rotary Knob
Cancel / Local Cancels the setup operation if the instrument is in the local status. Returns the
instrument to the local status if it is in the remote status.
On/Off Used to enable or disable the channel. Turns the channel off if it is in the output
status even if it is in the remote status. One switch on 1-channel models, and two
switches on 2-channel models.
The switch turns green if the channel is enabled.
The switch turns red if the channel is in the high voltage state.
Numeric/alpha
keys
Used to enter the value for setup parameters such as the source output value, limit
value, and message, specified by the field pointer. The value can be changed if the
field pointer is in the EDIT (green) status.
Rotary knob If the field pointer is in the MOVE (blue) status, turning the knob moves the pointer.
Pressing the knob fixes the pointer position and changes the pointer status to EDIT
(green).
If the field pointer is in the EDIT (green) status, turning the knob changes the value
of the setup parameter specified by the pointer. Pressing the knob fixes the value and
changes the pointer status to MOVE (blue).
If the field pointer is in the EDIT (green) status on a setup field other than the
Source field and the Limit field, turning the knob changes the setting value. The
value is applied by pressing the knob.
If the field pointer is in the EDIT (green) status on the Source or Limit field, turning
the rotary knob changes the display value and updates the source channel output in
real time. However, if the digit pointer is available, the source channel works
depending on the setting of the real time update (the setting of the Immediate V/I
Update by Knob field). For the Immediate V/I Update by Knob field, see “Display
Preference dialog box” on page 4-48.
If the digit pointer is on a digit of a numeric value entry field, turning the knob
changes the value of the digit. Note that changing the value from 9 to 0 or from 0 to
9 changes the value of the next digit.
If the digit pointer is on the decimal point of a numeric value entry field, turning the
knob moves the decimal point if the Immediate V/I Update by Knob setup is OFF.
Left and right keys If the field pointer is in the MOVE (blue) status, pressing the key moves the pointer.
If the field pointer is in the EDIT (green) status, pressing the key changes the value
of the setup parameter specified by the pointer.
