USER MANUAL

FOR UNITED KINGDOM ONLY

NOTE: This lead/appliance must only be wired by competent persons

WARNING: THIS APPLIANCE MUST BE EARTHED

IMPORTANT: The wires in this lead are coloured in accordance with the following code:

Green/ Yellow:

Blue:

Brown:

Earth

Neutral

Live (Phase)

As the colours of the wires in main leads may not correspond with the colours marking identified in your plug/appliance, proceed as follows:

The wire which is coloured Green & Yellow must be connected to the

Earth terminal marked with the letter E or by the earth symbol or coloured Green or Green & Yellow.

The wire which is coloured Blue must be connected to the terminal which is marked with the letter N or coloured Blue or Black.

The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red.

If in doubt, consult the instructions provided with the equipment or contact the supplier.

USER MANUAL

This cable/appliance should be protected by a suitably rated and approved HBC mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, cable of

0.75mm

2

should be protected by a 3A or 5A fuse. Larger conductors would normally require 13A types, depending on the connection method used.

Any moulded mains connector that requires removal /replacement must be destroyed by removal of any fuse & fuse carrier and disposed of immediately, as a plug with bared wires is hazardous if a engaged in live socket. Any re-wiring must be carried out in accordance with the information detailed on this label.

3.PRECAUTIONS BEFORE OPERATION

3-1.Unpacking the Instrument

The product has been fully inspected and tested before shipping from the factory. Upon receiving the instrument, please unpack and inspect it to check if there is any damage caused during transportation. If any sign of damage is found, notify the bearer and/or the dealer immediately.

3-2.Checking the Line Voltage

The product can be applied by any kind of line voltages shown in the table below. Before connecting the power plug to an AC line outlet, make sure the voltage selector of the rear panel is set to the correct position corresponding to the line voltage. It might be damaged the instrument by connecting to the wrong AC line voltage.

WARNING. To avoid electrical shock the power cord protective grounding conductor must be connected to ground.

AVERISS: Pour éviter les chocs électriques, le fil de terre du cordon secteur doit impérativement être relié à la terre.

When line voltages are changed, replace the required fuses shown as below:

5. OPERATION METHOD

5-1. Output Voltage/Current Setting

At first, ensure that the window now is at the Output Voltage/

Current setting or the output value display. or

--Output Voltage Setting:

Press [Vset/Iset] to set the cursor to the position for voltage input, and modify the setting value with wheel knob. Right now, can use

[F/C] to switch over the input of 1V step or 10mV step.

Example:

If want to set the voltage as 12.34V, first using the [F/C] knob to switch the cursor to 10mV step and adjust the value to 34, then switch the cursor to 1V step and adjust the value to 12 to complete the modification.

>>

>>

PS. If the output is on now, the output voltage value will be varied with the setting of the knob.

--Output Current Setting:

After pressing [Vset/Iset] to set the cursor to the position for current input, modify the setting value with wheel knob. Right now, use [F/C] to switch over the input of 100mA step or 1mA step.



10




USER MANUAL

Example:

If want to set the current as 1.234A, first using the [F/C] knob to switch the cursor to 1mA step and adjust the value to 34, then switch the cursor to 100mA step and adjust the value to 12 to complete the modification.

>>

>>

Note: 1. When the load current through output terminal exceeds the setting value, the instrument is operated in the C.C. mode, if not exceeds the setting value, the instrument is operated in the C.V. mode.

2. When the maximum output voltage is larger than 36V, its adjustable step is 20mV the minimum while the maximum output current is larger 3A, its adjustable step is 2mA the minimum.

5-2.Over Voltage /Current Protection Setting

--Over Voltage Protection Setting:

Set to OVP SET window by pressing [MENU], modify the setting value with the wheel knob and press [ENTER]. The modification can be done by using the [F/C] knob to switch over the input of

1V step or 10mV step.

--OVP Status Clear Up:

When the output voltage exceeds the setting voltage, the output of the instrument will be off and get into OVP mode by displaying

“OVP Error. Press “LOCAL” to reset” on the panel. Just press

[LOCAL] to clear OVP status and back to previous status.

USER MANUAL

--Over Current Protection Setting:

Set to OCP SET window by pressing [MENU], Turn on/off the

OCP with the wheel knob and press [ENTER]. If OCP is on, when the output current equals or exceeds the curr ent value setting, the output of the instrument will be off and get into over current protection mode by displaying “OCP Error. Press “LOCAL” to reset” on the display. Just press [LOCAL] to clear OCP status and back to previous status.

5-3. The Display C ontrast Setting

Set to Contrast Set window by pressing [MENU], modify its setting value with the wheel knob and press [ENTER].

5-4. The Buzzer Setting

Set to Buzzer Set window by pressing [MENU], turn on or off the buzzer with the wheel knob, then press [ENTER].

5-5.GPIB/RS232 Interface Setting

Set to Interface window by pressing [MENU]. If the GPIB is displayed, the Address value window will be appeared, if the

RS-232 is displayed, the Baud Rate window will be appeared, then using the wheel knob to modify the value and press [ENTER] to complete the setting.

Note: The system will detect the interface used at present automatically, and switch the detected interface over the setting interface of GPIB or RS-232.

Example:

1) If want to set the GPIB address value to 15:

Set to interface window by pressing [MENU], and adjust the address value to 15 with the wheel knob and press [ENTER] to

USER MANUAL steps.

[Step 3.1]

Now input the current value (Max.) measured by the DMM with the knob and press [ENTER]. During the current value input, use the

[F/C] button to switch over the input of 100mA range (100mA/step) or 1mA range (1mA/step).

Note: The DMM selected for the measurement must have the resolution of four digits of the decimal point at least (0.1mA).

Also the input value is to take three digits of decimal point of effective value (1mA) and run off the rest.

[Step 3.2]

Now input the current value (Min.) measured by the DMM with the knob and press [ENTER]. During the current value input, use the

[F/C] button to switch over the input of 100mA range (100mA/step) or 1mA range (1mA/step).

Note:The DMM selected for the measurement must have the resolution of four digits of the decimal point at least (0.1mA).

Also the input value is to take three digits of decimal point of effective value (1mA) and run off the rest.

[Step 4]

Switch the Calibration selection window to O.V.P. calibration item with the knob and press [ENTER] getting into O.V.P calibration steps.

[Step 4.1]

USER MANUAL

At present, the window will indicate the progress of OVP calibration.

When the calibration is completed, it will jump out of the window.

[Step 5]

When above calibration steps has been confirmed correctly, switch the calibration selection window to SAVE window with the knob and press [ENTER] to complete the whole calibration procedures.

[Step 6]

If the calibration procedure is not necessary to be stored, just switch the calibration selection window to Exit window and press [ENTER] to leave the calibration procedure.

6-4. Cleaning

To clean the power supply, use a soft cloth dampened in a solution of mild detergent and water. Do not spray cleaner directly onto the instrument, since it may leak into the cabinet and cau se damage. Do not use chemicals containing benzine, benzene, toluene, xylene, acetone, or similar solvents. Do not use abrasiv e cleaners on any portion of the instrument.
