4.2 Connecting to a Circuit:
Use the pluggable terminal blocks at the top of the device to connect to your target circuit. Ensure correct polarity and secure connections.
- Identify the V (voltage) and mA (current) output terminals.
- Connect the appropriate wires from your circuit to the corresponding terminals on the SG-002.
- Ensure all connections are firm to prevent accidental disconnections during operation.
5. Operating Instructions
5.1 Powering On/Off:
Slide the ON/OFF switch located on the side of the device to the 'ON' position to power on. Slide to 'OFF' to power off.
5.2 Selecting Output Mode:
Press the 'MODE' button to switch between Voltage (V) output mode and Current (mA) output mode. The active mode will be indicated on the display.
5.3 Adjusting Output Value:
Rotate the large rotary encoder knob clockwise to increase the output value and counter-clockwise to decrease it. The digital display will show the real-time output value.
5.4 Saving Parameters:
To save a set voltage or current value, press the rotary encoder knob. The device will store this value, and it will be displayed directly upon restart, eliminating the need for re-adjustment each time.
