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.
