Chapter 4 Troubleshooting
Question 1: What to do if a short circuit on output terminal occurs?
Answer1: There is over current protection and short circuit protection inside the power, so
current will be controlled in a safety range.
Question 2: Is it abnormal that the
CH3 overload indicator is lit?
Answer 2: No, that only means the current value reaches 3.2A, 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 are 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 failure?
Answer 4: Upgrade via guide procedure can be used if the upgrade failed (see detail in
"2.11 Upgrade firmware").
Question 5: Why is the practical value not the same as the set value (over performance
standard) and even changes slowly on startup?
Answer 5: It's normal. On startup, components inside the instrument are in the process of
stabling and readings will be stable after about 30 minutes.
Question 6: What if the external fuse blows automatically when the unit is switched on?
Answer 6: First of all, make sure the fuse is the current value (For instance: the fuses B and
C should be 16A and 10A respectively). If the failure still exists with the correct fuse, check if
there is a short circuit, or return it to the factory to have it repaired by qualified personnel.
