When the instrument is in the output state, the current window shows an actual current, and while the
instrument is closed, the current window shows a setting current.
4.3 Voltage setting operation
The range of voltage setting is between 0V and the maximum voltage setting value, and you can use
the following three methods to set the output voltage value through the front panel.
Method 1: After power is on, you can directly press “
▲
” and “
▼
” to change the voltage setting value.
Method 2: Press “V-Set”
+
“0 to 9 numeric keys”, and then press “Enter” to set the voltage value.
Method 3: Change the voltage setting value through turning the knob left or right.
4.4 Current setting operation
The range of rated current setting is between 0V and the full rated output current,
Method 1: Operating steps
1. Press “I-Set”
2. Press “0 to 9 numeric keys” to input the current value you need
3. Press “Enter” for confirmation
Method 2: Change the voltage setting value through turning the knob left or right.
4.5 Access operation
The power supply can respectively store some commonly used parameters into 9 groups of
non-volatile memory for users to recall for use quickly. You can use the keys of “Save”and “Recall”
on the front panel to implement the access operation of (0~9) groups in storage area.
Storage contents include: 1. Voltage setting value 2. Current setting value
You can use “Save”
+
”0 to 9 numeric keys” and press “Enter” to store the parameters of power supply
to the designated storage area.
You can use “Recall”
+
“0 to 9 numeric keys” and press “Enter” to recall the parameters from the
designated storage area for use.
4.6 Early warning function of battery charging, and setting of higher and lower limits of current
Press “shift” and then press numeric key “8” to enter the early warning function of battery charging.
As for the setting of higher and lower limits of current, the screen displays in turn as follows:
L X.XXX
(lower limit of current)
H X.XXX
(higher limit of current)
Use numeric keys to change setting value and press “Enter” for confirmation, and it will alarm when it
is out of range!
Chapter 5 Remote Operating Mode
5.1 Communication between power supply and host
The power supply can be connected to the host interface by DB9 plug on the rear panel through the
level conversion circuit, and the following contents can help you understand how to control the output
of power supply through the host.
1. Communication setting
Before conducting the communication operation, you shall firstly match the power supply with the
following parameters which control the host:
(1) Baud rate: 9600
(2) Checkout: NONE (NONE,EVEN,ODD)
