5.1 Turn On/Off the Output
Press the orange ON/OFF key to turn on/off the Fixed output.
Press the blue ON/OFF key to turn on/off the Channel output.
The ON/OFF key is lighted when the channel is on.
Note:
When the channel output is short-circuited, the instrument will sound an alarm.
5.2 Set the Output Voltage/Current
5.2.1 Set the Fixed Output Voltage
Press the 3.3V key or 5V key to switch the fixed output voltage between 3.3V/5V.
5.2.2 Set the Output Voltage/Current of Channel
You can set the output voltage/current through input box. The range of voltage rating is
0～30V; the range of current rating is 0.02～3A.
Note: The output voltage/current cannot be set in Timer status. If you want to set it, you
should exit the Timer status first.
(1) Press the Volt/CV or Curr/CC key, the input box of Channel output voltage/current
will pop up.
(2) The key light will start blinking, indicating to input, there are two methods to change
the value.
Modify: Turn the knob or press the
▲ / ▼ direction key to change the value by the
unit of cursor position, hold down the
▲ / ▼ direction key to change continuously.
Press the ＜ / ＞ key to move the cursor.
Input: Use the numeric keys to enter a desired value, the original value will be
cleared, and display the value you entered.
(3) Press the key to confirm.
Note: If the input value is out of the rated range, the box prompts "ERROR"; you need to
input another value within the rated range.
5.3 Over Voltage/Current Protection
When the Over Voltage Protection (O.V.P) or Over Current Protection (O.C.P) is enabled,
once the output voltage/current reaches the set value of O.V.P/O.C.P, the instrument will
cut off the output. The value of O.V.P/O.C.P which causes cutting off will turn red and
