Pressing the PARA/
INDEP button for over 2
secs will also inadver-
tently change the state
of OVP when exiting
PARA mode.
The voltage at the out-
put is displayed on both
CH1 and CH2 displays.
The current at the out-
put is the sum of the
currents on the CH1
and CH2 displays
do not work (even though
OVP and OCP LEDs might
be on).

The OCP and OVP enabled
state are not saved with any
memory, and are unaffected by
recalling memories. The OCP
and OVP enabled states are al-
ways set to off when the power
supply is powered up with the
mains switch.
You might consider manually
wiring the channels (in indepen-
dent mode) in series or parallel in-
stead of using the built-in SER and
PARA modes. While there would
be no tracking, you could use OVP
and OCP.
If you press the currently selected memory key you do not have
to wait for it to stop blinking
Voltage setting:
- For use in constant
voltage mode: this is the
desired constant voltage.
- For use in constant
current mode: this is the
desired voltage limit.
- If you enable
overvoltage protection,
the output switches off
automatically if the volt-
age exceeds this value.
Current setting:
- For use in con-
stant voltage mode:
this is the desired
current limit.
- For use in con-
stant current mode:
this is the desired
constant current.
- If you enable
overcurrent protec-
tion, the output
switches off automati-
cally if the current ex-
ceeds this value.
You can change the val-
ues with the output
switch on, in which case:
After about 4 seconds
without you making fur-
ther changes (or immedi-
ately if you press the cur-
rently selected memory
key), the value being
changed is saved to
memory, ceases to flash,
and the display resumes
showing the measured
value at the output.
Since the desired constant voltage is also the voltage OVP limit, OVP cannot
protect you against inadvertently exceeding the OVP limit using the adjust-
ment knob.Since the desired constant current limit is also the OCP limit, OCP
cannot protect you against inadvertently exceeding the OCP limit using the ad-
justment knob.
