FAQ:
1. SPS-C3010 with output switch VS normal version without output switch.
- SPS-C3010 with output switch: It is simple to set voltage and current. The output button is milky white when it is off, there is no current output at this time, and the power position shows OFF. After turning on, the button will light up, at which time it will output normally, and the power position will display a number.
- Normal version without output switch: it requires a short circuit to regulate the current. There are many operational processes. To set the current, first adjust the voltage to about 5V, then plug in output cables, contact the two clips for short-circuit connection, and then use the current knob to adjust the current.

2. Why does the screen show 0, but the screen does not respond after adjusting the voltage?
First see if the indicator is in the CC position and it may be that the current has been adjusted to 0. Adjust the current slightly, when the indicator is in the CV position, adjust voltage and it can display normally.

3. Can the maximum voltage and current be displayed?
The maximum voltage and current displayed at the same time needs to meet the conditions: I = U/R. For example, it can be adjusted to 30V and 10A at 3Ω.

4. What is current or voltage limit?
If the resistance is another value, such as 2Ω, in actual use, it will be limited by Ohm's law (I=U/R), and the displayed current can only be 10A at 10V. If you want a larger voltage, you need a larger current, but it can only display 10A, so the voltage displayed is limited, and the voltage displayed cannot be 30V.
