Chapter 5 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 current will be controlled in safety range.
Question 2:
Is it abnormal that the
CH3 overload indicator is lit ?
Answer 2:
No, that only means the current value reaches 3A, which is the
maximum value within its range, and now power supply can be used
continuously with the suggestion that decrease the output load.
Question 3:
Is it normal that in the series mode, voltage and current value of a
channel is respective 0V and not 0A, while that of another channel is both
not 0?
Answer 3:
Yes, because when current output load is higher than the limited
current value, the working mode turns to CC from CV.
Question 4:
How to deal with the upgrade failed?
Answer 4: please do it again.
Question 5:
why the practical value is not the same with the set value (over
performance standard) and even changs slowly on startup?
Answer 5:
It’s normal. On startup, components inside the instrument are in the
process of getting stable, readings will be stable about 30 minutes later.
Question 6:
what if the circuit air switch turns off automatically when power
on?
Answer 6:
First of all, make sure whether the rating of the air switch is proper
or not (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 is a
short circuit, or return it to the factory to have it repaired by qualified personnel.
