When using electrical appliances, basic safety precautions should always
be followed to reduce the risk of re, electric shock and injury to persons or
property.
Read all instructions before using the appliance and retain for future reference.
• Check that the voltage indicated on the rating plate corresponds with that of the
local network before connecting the appliance to the mains power supply.
• Do not operate this appliance with a damaged plug or cord, after a malfunction or
after being dropped or damaged in any way.
• Check the product before use for any damage. Should you notice any damage on
the cable or casing, do not use.
• This appliance contained no user-serviceable parts. All repairs should only be
carried out by a qualied engineer. Improper repairs may place the user at risk of
harm.
• Do not block or obstruct the cooling fan vent opening.
• Avoid severe impacts or rough handling that leads to damage.
• Do not discharge static electricity.
• This appliance can be used by children aged from 8 years and above and persons
with reduced physical, sensory, or mental capabilities or lack of experience and
knowledge if they have been given supervision or instruction concerning use of the
appliance in a safe way and understand the hazards involved.
• Children should be supervised to ensure that they do not play with the appliance.
• Always disconnect from the mains when the product is not in use or before
cleaning.
• Do not use the appliance for any purpose other than that for which it is designed.
• Do not operate or store in an environment of high humidity or where moisture may
enter the product as this can reduce insulation and lead to electric shock.

STEADY STATE FUNCTION MODES
• The electronic load can work in the following 4 steady-state modes.
Constant Current Operation Mode CC
Note: In constant current mode, the load holds the tested equipment on the set current
no matter how the input voltage changes.
• Operation Method:
1. Press the CC button on the
panel
to enter constant current operation mode.
2. Set the desired constant current through the numerical buttons
3. Press ENTER to conrm.
4. Press the ON/OFF button to start the electronic load.
Constant Voltage Operation Mode CV
Note: In constant voltage mode, the load holds the tested equipment on the set voltage
no matter how the input current changes.
• Operation Method:
1. Press the CV button on the panel to enter constant voltage operation mode
.
2. Set the desired constant current through the numerical buttons.
3. Press ENTER to conrm.
4. Press the ON/OFF button to start the electronic load.
Constant Resistance Operation Mode CR
Note: In constant resistance mode, the load holds the tested equipment on the set
resistance no matter how the input voltage and current change.
• Operation Method:
1. Press the CR button on the panel to enter constant voltage operation mode.
2. Set the desired constant current through the numerical buttons.
3. Press ENTER to conrm.
4. Press the ON/OFF button to start the electronic load.
3
Constant Power Operation Mode CW
Note: In constant power mode, the load holds the tested equipment on the set wattage
no matter how the input voltage and current change.
• Operation Method:
1. Press the CW button on the panel to enter constant voltage operation mode.
2. Set the desired constant power through the numerical buttons.
3. Press ENTER to conrm.
4. Press the ON/OFF button to start the electronic load.
Note: Values for all inputs can be entered using either the rotary input selector, up or
down buttons or number keys in all modes.
Setting the maximum values of a load
• Setting low voltage (18V), low current (3A) and below will improve the accuracy.
Example: Setting the max current to 3A, max voltage to 18V and max power to 100W,
and the max resistance to 1000ohms.
1. Press SHIFT+CV to enter settings mode.
2. Set the required current (3A) value and press ENTER.
3. Press CV to enter next input mode.
4. Set the required voltage (18V) and press ENTER.
5. Press CV to enter next input mode.
6. Set the required power (100W) and press ENTER.
7. Press CV to enter next input mode.
8. Set the desired resistance (1000Ω) and press ENTER.
9. Press ESC to complete and enter steady mode. The steady mode status is
displayed.
Storing steady state values and recalling from memory
Note: The memory can save and recall 100 sets of steady mode settings.
• Once a set of values are input press SHIFT+2 to enter memory storage mode.
• Each location can be saved as a numerical identier 1-100.
• Press ENTER to store the location.
Restoring steady state values from memory
Press CALL+2 to enter memory storage mode.
• Select the location of the stored values required from 1-100.
• Press ENTER to recover the saved values.
Quick access steady state value memory
For commonly used values there are 5 quick access and storage buttons.
• Once a set of values are input press button M1 to M5 to store the settings.
• To recover the required saved settings instantly, press M1 to M5.
Short circuit function
Note: the load will make the tested equipment output the max current.
• Press SHIFT+7 to enter the short circuit test mode.
