3. Operation Introduction
3.1 Front Panel Operation
1)
The applied Voltage/Current Unit for this series instruments is Volt (V) and Amp (A) .
2)
The factory setting is in panel operation mode that enable user to operate the instruments directly from panel
control knob.
3)
When the remote controller is on line, the
[Lock]
button backlight turns on and the operation can only be
proceed through it. But the
[On/Off]
button is still available for operation. All other button operations are
closed unless press
[Lock]
button again to unlock the front panel. The
[Lock]
button backlight turns off.
4)
The output of power supplies is always at OFF status after power on.
3.2 How to Input
3.2.1 Input via Numeric buttons
Use numeric buttons from 0 to 9 and decimal point to input targeted values, and then press
[Enter]
button to
confirm input. If the input value is wrong, press
[Clear]
button to clear the present values, then input correct
values.
3.2.2 Input via Step Button
In practices, a set of voltage or current value with same interval is commonly used. It is complicated and time
consuming to input this kind of value by repeatedly pressing the numeric buttons and
[Enter]
button. It is also
complex by using the rotary knob because voltage or current value may be multi-digit. It is very convenient to use
the step input method. Every press on the corresponding button makes the voltage or current increase or decrease
by a step value. The input value is validated automatically without pressing
[Enter]
button
For example, to generate a series of voltage with interval 1.1V, press buttons sequentially as below:
Press
[Shift]
[4]
to enter function setting mode.
Press
[Menu]
again until
“Utility V Step” is shown on the LCD,
Press
[1]
[.]
[1] [Enter]
to complete step voltage value setup,
Press
[V-set]
until
“Voltage” is shown on the LCD,
Press
[
]
to increase the voltage by 1.1V or press
[
]
to decrease the voltage by 1.1V.
Repeat this operation, a series of voltage with equal interval can be generated. The same procedure can be
used for the current operation.
3.2.3 Input via Rotary Knob
In some applications, it requires to adjust the output signal continuously. It is convenient to use rotary knob to
make adjustment. Press buttons
[
]
or
[
]
to move the cursor left or right. Rotate the knob to the right to
continuously increase the cursor-located digit by 1 and make the carry to a higher unit position. Rotate the knob to
the left to continuously decrease the cursor-located digit by 1 and make the carry to a lower unit position. The
modified value is validated immediately without pressing the
[Enter]
button.
