When OCP or OVP trips the output
off:
- A beep is emitted (if beep is en-
abled),
- The OUT and CV/CC LEDs re-
main on for CH2 (but turn off for
CH1)
- The settings values for voltage
and current are displayed (instead of
measured values), as is usual when
the load is off.
The OCP and OVP LEDs
are situated on the CH1
display. However they
are used for displaying
the OCP and OVP state
for both channels. They
display the state of OCP
and OVP for whichever
channel the OCP or OVP
buttons were last
pressed for. Pressing ei-
ther the OCP or OVP
button for a channel will
toggle its state and up-
date both the OCP and
OVP LEDs.
If you press and hold the
OCP/BEEP button for 2
secs to turn beep on/off,
it inadvertently changes
the state of channel 1
OCP. Likewise, pressing
the PARA and SER but-
tons for 2 seconds will in-
advertently change the
state of channel 2 OCP
or OVP when entering in-
dependent mode.
