IMPORTANT SAFETY INSTRUCTIONS
For your own safety and the safety of other people, and to prevent the
product from damage, we suggest you following the instructions not
only for operating and maintaining the product, but also for keeping it in
storage.
Environment
* The product is constructed for indoor use.
* Condensation may occur after the product has been
shipped from cold to warm area. Await the product two hours or longer
to be totally dry before powering on to it.
* Never place the product near water side or in wet area.
* Never place the product under direct sunlight or near heat
source.
* Never block the ventilation openings at the enclosure of the
product.
* Never place any heavy object on the product and severe
impact or rough handling that could lead damage to it.
Storage
* Location: indoor
* Relative humidity: <80%
* Temperature: -10℃~ 70 ℃
Opteration
* The product is rated at AC input 85~264V, 47~63Hz mains
* Connect the product to an earthed wall receptacle with an
international safety approved power cord.
* Be careful. A power circuit changes from open to short
could cause high current sparks to injure eyes. A power circuit changes
from short to open instantly induce high voltage and arc, to shock
people and injure their eyes.
Service and maintenance
* The product operates with hazardous high voltage ( near
DC 380V or AC 267V) inside. Only qualified personnel can carry out the
service.
* The product still keeps hazardous voltage inside even after
it has been switched off for a while.
P.2
* Before performing any service, disconnect the product from
the mains and await it until no harmful voltage remains at the terminals
of bulk capacitors.
* Please replace the fuse only with the same ratings of
amperage and voltage to avoid risk of fire.
* This is a Class A device which can cause RF interference
within the home.
* The product is operated only when the case is securely
closed and screwed up.
* While operating the product, the wearing of metal or other
conducting jewelry such as chains, bracelets, rings, etc. is not
recommended.

OPERATION
Recommended fingering for keys (buttons) press.
Reading mode
Please refer to the figure 1, left half part.
Upon AC powering on the C³V Series, the unit unconditionally enters
the “Reading mode” with the green V-LED lit. The value on the “Meter &
display” was the last time setting in memories. By pressing Enter key
momentarily (PEK), user can read the voltage, the current (as long as a
load is connected and the Output key is pressed) and the inside
temperature in circulation. The “Meter & display” is now measuring and
displaying both the output voltage and current values for user to read.
P.4
Figure 1
Setting mode
Please refer to figure 1, right half part.
By pressing the Enter key for >3 seconds (PE3), the unit will be in
“Setting mode” after a short beeping. A blinking V-LED or a blinking
A-LED and a blinking decimal point on the “Meter & display” are
together to prompt the user for setting input. By pressing the Enter key
momentarily, blinking V-LED or blinking A-LED will be selected. Now
the user can push the Up key or Down key to adjust (or set) the voltage
or current for output. At last the user can use the same PE3 to end this
Setting mode and go back to Reading mode, and vice versa.
In fact, the setting values of both voltage and current are the maximum
output limits of the unit.
The unit guarantees to output <= the maximum values. Once you leave
the Setting mode, the two values will be updated and saved in
memories till next setting.
Note 1:
In CV operation, the setting voltage is always the same as output
voltage while the setting current is greater than the real output current.
In CC operation, the setting current is always the same as output
current while the setting voltage is greater than the real output voltage.
Note 2:
If the red “cc- LED” is lit, the unit is working in CC operation otherwise
in CV operation.
Between the two modes
By pressing the Enter key for >3 seconds (PE3), the unit will go directly
from voltage reading to voltage setting and vice versa. This function
makes user more efficiency in circuit experiment.
