Output Checking

To make sure the instrument can correctly respond to operation from the front panel, please perform the output checking, which includes voltage checking when all channels are with no load and current checking when short circuit occurs.

1. Output voltage checking

(1) With the instrument no load, turn on the power, and make

sure the current value displaying is not zero;

(2) Check the output voltage of CH1/CH2

Turn on CH1/CH2 channel and the instrument acquiescently

works in CV mode. Check whether the voltage value is adjustable from 0V to 32V.

2. Current output check

(1) Turn on the power. (2) Check the output current of CH1/CH2.

Use an insulated wire to connect the positive and negative

terminal of CH1/CH2; Turn on CH1/CH2; Select voltage and revolve the knob to set the value to 32V; Select current and revolve the knob to set the value to 0A;

Check whether the current value is adjustable from 0A to

3.2A.

SPD3303C Quick Start 9

SIGLENT

Output Summary

SPD3303C is designed with three independent outputs, two of which are adjustable in voltage value and the other includes a set of selectable voltage values: 2.5V, 3.3V or 5.0V.

Independent/Parallel/Series

SPD3303C has three output modes: independent, parallel and series that could be selected through the track switch on the front panel. In independent mode, the output current and voltage are controlled respectively. In parallel mode, the current value is twice that of single channel. In the series mode, the voltage value is twice that of single channel.

Constant Current/Voltage

In constant current mode (series/track mode), the current value is rated. The indicator light displays red and the voltage value are under its rating. The instrument will automatically turn to constant voltage mode when the current value gets less than its dating. (In parallel mode, the accessory channel remains in constant current mode neglecting shift of the current value.)

In constant voltage mode, the voltage value is rated. The indicator light displays green and the current value are under its rating. The instrument will turn to constant current mode when the current value gets up to d its dating.

10 SPD3303C Quick Start

SIGLENT

CH1/CH2 Independent Output

Instruction CH1 and CH2 are working in independent mode and

insulated from the ground.

Output ratings 0~32V/0~3.2A

Operation steps

1. Make sure that parallel/series mode is off.

2. Connect load to the positive and negative terminals of CH1/CH2.

3. Set the voltage (current) value of CH1/CH2: Firstly, press V (or A ) to select the voltage (current) parameter needed to modify. Then revolve the multi-function knob to set the wanted value (You could press FINE to make accurate adjusting). Coarse adjusting: 0.1V or 0.1A each step. Fine adjusting: the least precision each step.

4. Open output: Press ON/OFF button to turn on the output, the

channel works in CC or CV mode and its indicator light gets lighted immediately.

SPD3303C Quick Start 11

SIGLENT

CH3 Independent mode

Instruction CH3 works independently from CH1, CH2, and its

voltage and current ratings are: 2.5V, 3.3V, 5V, 3.2A.

Output ratings 2.5V/3.3V/5V, 3.2A

channel.

2. Select the wanted voltage value by moving the “DIP switch” of

CH3.

3. Open the output: Press ON/OFF button to turn on the channel

and the indicator light gets lighted immediately.

CV CC

When the current value gets higher than 3A, the overload indicator light turns red and the working mode of CH3 turns to CC mode from CV mode.

Note: “Overload” does not mean abnormal operation.

12 SPD3303C Quick Start

SIGLENT

CH1/CH2 Series Mode

Instruction：In the series mode, CH1 and CH2 are linked internally

Operation steps：

1. Press the SER to start the Series mode, and the indicator light

turns bright

2. Connect the load to the positive terminal of CH2 and the

negative terminal of CH1;

3. Turn on CH1 and set its current value to 3.2A. In the default

setup, the instrument works in “Coarse”, you can turn to “Fine” by pressing FINE;

Coarse: 0.1V or 0.1A each step; Fine: the least precision each step;

4. Turn on CH1and set the output voltage/current value by

revolving the multi-function knob;

5. Press ON/OFF button to open the output.

Note: You can identify the current working state “CC” or “CV” by referring to the indicator light.(red means CV, green means CC).

CH1/CH2 Parallel Mode

Instruction In the parallel mode, CH1 and CH2 are linked internally

into one channel controlled by CH1. The output current value is twice as much as the single channel.

Output ratings 0~32V/0~6.4A

Operation steps:

1. Press the PARA button to start Parallel mode, and the indicator

light turns bright immediately；

2. Connect the load to the positive and negative terminals of CH1；

3. Press ON/OFF button to open the output and the indicator light

turns bright. Turn on CH1 and set its output voltage/current value by revolving the multi-function knob. In the default setup, the instrument works in “Coarse”, you could turn to “Fine” by pressing FINE button.

Note: You can identity the current working state “CC” or “CV” refer

to the indicator light.(red means CV, green means CC). In parallel mode, CH2 only works in CC mode.

Chapter 4 Troubleshooting

Question 1: What to do if there occurs a short circuit on output terminal? Answer1: There are over current protection and short circuit protection inside

the power, so the current will be controlled in safety range.

Question 2: Is it abnormal that the CH3 overload indicator turns bright ? Answer 2: No. That only means the current value reaches the maximum 3A.

For better use, you’d better decrease the output load.

Question 3: Is it normal that in the series mode, the voltage and current value of one channel is respectively 0V and not 0A, while that of another channel proves not to be 0? Answer 3: Yes. Because when the current output load gets higher than the limited, the working mode turns to CC from CV.

Question 4: what to do if upgrading fails? Answer 4: please do it again.

Question 5: Is it normal that the practical value is a little different from the value you set (exceed performance standard), or even shifts slowly on startup? Answer 5: Yes. During the startup, components inside the instrument are getting stable in 30 minutes, which lead to going up of the temperature.

Question 6: What if the circuit air switch turns off automatically when power on? Answer 6: First of all, make sure if the rating of the air switch is proper (For instance: the rating of air switch B and C should be respectively over 16A and 10A). If the failure still exits beyond the reason, check if there occurs a short circuit, or return it to the factory to have it repaired by qualified personnel.
