the equipment. Check whether the instrument is subject to cracking or is lack of plastic. Do not operate the instrument in the environment with explosive gas, steam or dust.

 Observe all tags on the equipment before connection.  Do not install alternative parts on the instrument or perform any

unauthorized modification.

 Do not use the equipment when the removable cover is dismantled or

loose.

 Please use the power adapter supplied by the manufacturer to avoid

accidental injury.

 We do not accept responsibility for any direct or indirect financial damage

or loss of profit that might occur when using the instrument.

Chapter2 Basic Operation

This Chapter introduces related operations for keys on the front panel of I T6412 power supply. When the keys on the front panel are used for operation, the power supply should be under local operation mode, under which, the User can perform all functions of the power supply through the front panel keys. The power supply is defaulted under local operation mode at initialization.

2.1 Local/Remote Operation Mode Switching

The power provides local and remote operation modes. These two modes can be switched through communication commands. At initialization, the default value is local operation mode.

 Local operation mode: for operating related functions through keys on th e

instrument.

 Remote operation mode: for operating related functions through the PC

connected to the power supply. When the power supply is under the remote operation mode, except Print key, other keys on the panel are disabled. By sending SYSTem:LOCal command, switch to local operation mode. The output parameters of the power supply are not affected by change of the operation modes.

2.2 Output On/Off Control

Press the [On/Off] key on the Channel 1 (CH1) or Channel 2 (CH2) on the front panel of power supply to control output switches of the corresponding channels of power supply. When the [On/Off] key is lighted on, the ou tput is switched on; and when the [On/Off] key is lighted off, the output is switched off. W hen the power supply is on, the working state icon (CV/CC) on the LCD will be lighted on.

Note

To avoid wiring sparkling, press the [On/Off] key to switch on output after connection of the power supply and the DUT. If there is no output after it is switched on, check the voltage/current set value. Please set the voltage and current values as non-zero before switching on the output again.

Configuring Output-off State

This item is used to set the status after the power output is turned off. Select Menu > Config > Conf2 to enter configuration me nu interface. Press up o r dow n keys to select Output-off, and then press [High Impedance], [Normal], [Zero] or [Relay off] soft keys on the right side to set the output off status.

 Select High Impedance. After the power output is turned off, the output

terminals of the power supply can be seen as a DC impedance (100k to 400k). The impedance values of different models are different.

 Select Normal. After the power output is turned off, if the output voltage is

0V, the output current is 0.05% of the output rated value.

 Select Zero. After the power output is turned off, if the output voltage is 0V,

the current setting value keeps the value when the output was turned on.

 Select Relay off. After t he power output is turned off, use the relay to

disconnect the internal circuit and external load. The isolation impedance is over 1 GΩ.

7.4 Contact of ITECH Engineers

This section describes operations to be carried out by the user in case of failure of the instrument.

Preparation before contact

When the instrument fails, you should make the following preparations before returning the instrument to ITECH for repair or contacting engineers.

1. Check all the items listed in the “Self-inspection of Equipment Faults” and confirm whether there are still some problems.

2. If there are still some problems, carefully read the contents of warranty services and warranty restrictions in the preface of the manual. Confirm that our instrument complies with warranty service conditions.

3. If you want to send the instrument to the manufacturer for repair, refer to instructions in “7.5 Returning Your Power for Service”.

Self-inspection of equipment faults

In case of failure of the instrument, self-inspect the following items. If the instrument failure can be eliminated via simple inspection, the maintenance cost and time can be saved. Please che ck the following items before contacting the engineer of ITECH.

 Check whether the power supply is powered up.  Check whether the power supply is started normally.  Check whether the instrument fuse is in good conditions.  Check whether other connectors are in good conditions and whether

cables, plugs and other parts are connected properly.

 Check whether the system configuration of the instrument is correct during

use.

 Check whether self-inspection of the instrument is successful and whether

the specifications and performance are within the indicator ranges.

 Check whether the instrument displays error information.  Use other instruments instead of this instrument for confirmation.

Collect the SN number

ITECH will constantly improve the product performance, availability and reliability. The service personnel of ITECH will record changes of each instrument. All relevant information is marked uniquely according to the serial number of each instrument. The equipment returned for repair must adopt the SN number as the tracking ID.

When you contact the engineer, the effective SN number of the instrument will be the effective guarantee for effective service and complete information. You can obtain the SN number of the instrument by the following ways:

Routine Maintenan ce

1. Press the [Menu] key to enter the menu setting page of t he power supply.

2. Select “System” to enter system menu page.

3. Press the [Sys Info] to enter “System Infomation” interface to view the product model, product SN, software version number and other information.

4. In this page, Serial is the instrument SN number. Please record the SN number.

Calibration Interval

ITECH suggests that the IT6412 power calibration frequency is 1 time/year.

7.5 Returning Your Power for Service

When you want to return your power to ITECH company, please read the following information .

Package the power supply for Shipment

When instruments are required for factory maintenance, please refer to the following steps to pack the instruments which need to send out.

1. Please put the instrument for maintenance in the original packaging materials, with the related accessories.

2. Please be as specified as possible about the nature problem. Send a copy of any or all of the following information:

 Any error messages that appeared on the power supply display.  Any information on the performance of the power supply.

 Power damage can r esult from using packaging materials other than those

specified. Please use the special packing when shipment , and shall be carried out in accordance with the deliv ery of packaging standard as far as possible.

 Never use styrene pellets in any shape as packaging materials. They do not

adequately cushion the po w er supply or prevent it from shifting in the carton. Styrene pellets cause power damage by generating static electricity and by lodging in the rear panel.
