6.3 Setting with the Keypad
Vset &
I
set
Voltage or current can be set using the numeric keypad.
Upon pressing a numeric key, the OK key will start to flash. When the
numeric value entry is completed, pressing OK causes the value to be
accepted and actioned. Entry can be abandoned at any point by
pressing ESC (Escape). The new value being entered is shown directly
below the meters in a smaller font size.
Entry is in volts or amps to a resolution of 0.001 volts and 0.001 amps for outputs 1 and 2, and
0.01 volts and 0.01 amps for output 3.
Entries need only to be completed as far as the desired digit of resolution, e.g. to enter 5.000
volts it is only necessary to enter 5 followed by OK.
Note that for output 1, the voltage resolution reduces to 0.01 volts when the 120V/3A range is
selected.
6.4 Setting with the Spin Wheel
Vset &
I
set
Voltage or current can alternatively be set using the spin wheel. The
wheel is disabled by default but can be enabled by pressing the key
below it which toggles its action on or off. When enabled the key is
illuminated. The wheel changes the output settings immediately, no OK
confirmation is required.
The wheel has a non-linear action. If it is moved slowly the value is
incremented in minimum steps (1mV/1mA for outputs 1 and 2, or
10mV/10mA for output 3). When the wheel is rotated more rapidly the
rate of increment is increased enabling the value to be changed quickly.
6.4.1 Spin Wheel Action Options
The action of the spin wheel can be changed from System Preferences
to reduce the speed-related increment rate if preferred. Three choices are available: Normal
(default), Reduced acceleration, or Single Digit Increment.
Making changes is described in section 10.3.
