Operation
3.1 Introduction
DC Power Supply can be operated manually or remotely via GPIB controller or RS-232C or
APG interface which is described in Chapter 5 and section 3.3.1.3. The manual operation
for using the front panel keyboard or rotary knob to input the data is described in this chapter.
NOTICE
If the operation mode is not saved before users power the instrument off, the operation mode
is manual (default) when power it on next time.

Setting Voltage & Current
There are two ways to set the output voltage (CV MODE) as Figure 3-1 shows:
Method 1:
1. Press
“
VOLTAGE
”, the cursor for V_SET on MAIN PAGE blinks.
2. Use the numeric keys (
0
~
9
) or turn the “Rotary” (
) knob to adjust the set value.
3. Press
“
ENTER
” to complete the voltage setting.
4. When using “Rotary” (
) knob for setting, the “
” and “
” keys can be used
to move the cursor to individual digit, and then turn the rotary knob to increase or
decrease the minimum unit of the set value.
5. Press
“
ENTER
” to complete the voltage setting.
6. Press
“
O U T P U T
” to output the set voltage
.
(Be noted that in order to remain the output in
CV mode the current setting must be larger than the load current, otherwise the output
voltage will not equal to the set voltage.)
