Basic Operation
1. Refer to the figure below to complete the pin connection.
2. Calculate the Mx and Mb under the Ch1, Ch2 menus according to the above
formulas.
The sample data used in this manual is shown in the table below.

8 V
in1
= -5 V
out1
= 0 50 250 By inputting a volt-
age of -5V to 5V to
pin 8, the actual out-
put voltage Vset is
controlled from 0 to
500V.

= 5 V
out2
= 500
9 V
in1
= -10 I
out1
= 0 1.5 15 By inputting a volt-
age of -10V to 10V
to pin 9, the actual
output current upper
limit Ilim is con-
trolled from 0 to
30A.
V
in2
= 10 I
out2
= 30
3. Press the composite keys [Shift]+[P-set] (System) on the front panel to en-
ter the system menu.
4. Use knob or Up/Down key to select Ext-Program and press [Enter].
5. According to step 2, set Mx and Mb of the corresponding pins.
6. Set the Ext-Program→On / Off to On to turn on the analog function.
7. Adjust the output of DC Power Supply 1 from -5V to 5V, and adjust the out-
put of DC Power Supply 2 from -10V to 10V.
The actual output voltage and current of the instrument will change accord-
ing to the following rules:
