time, the current output and voltage output drop to zero. Pressing
“
RESET
”
key
can stop the alarm except the second state.
(1) Voltage Window displays
“
oV
”
: it will alarm when the output voltage exceeds
93%~105% of protecting voltage which is set by user, please check the setup or
wire connections.
(2) Voltage Window displays
“
oT
”
: when the power supply output heavy current and
high power for a long time so as to cause high temperature of power tube inside
the case. The instrument will alarm when the temperature is over heated. Only
when the temperature falls to normal state can we operate the power again.
(3) Voltage Window displays
“
RVSF1
”
: the instrument will give RVSF1 alarm as the
sampled voltage is less than -2V, please check the connection. For instance, in
exterior sampling state, reverses the polarity of the four-terminal connection.
(4) Voltage Window displays
“
RVSF2
”
: the instrument will give RVSF2 alarm as
current is over 25mA between terminals of exterior sampling, please check the
connection. For instance, in interior sampling state, the load is supplied by exterior
sampling terminals.
(5) Voltage window displays "MIX": the instrument will give MIX alarm as the two
or more abnormities above appear, please check setup and wire connections.
○
19. The indicator for constant current working state: CC
As the power supply is in the
“
CC
”
or
“
current limiting
”
state, the indicator will
light.
○
20. The indicator for constant voltage working state: CV
As the power supply is in the
“
CV
”
or
“
voltage limiting
”
state, the indicator will
light.
