personal injury.
CAUTION: Indicates a potentially hazardous situation which will result in personal injury or
a damage to property including the product.
• Basic Precautions
Please observe the following precautions to prevent fire, burn, electric shock, and personal inju-
ry.
• Use a power cable rated for the voltage in question. Be sure however to use a power cable
conforming to safety standards of your nation when using a product overseas.
• When inserting the plug into the electrical outlet, first turn the power switch OFF and then
insert the plug as far as it will go.
• When removing the plug from the electrical outlet, first turn the power switch OFF and then
pull it out by gripping the plug. Do not pull on the power cable itself. Make sure your hands
are dry at this time.
• Before turning on the power, be sure to check that the supply voltage matches the voltage
requirements of the instrument.
• Connect the power cable to a power outlet that is connected to a protected ground terminal.
Grounding will be defeated if you use an extension cord which does not include a protective
conductor terminal.
• Be sure to use fuses rated for the voltage in question.
• Do not use this instrument with the case open.
• Do not place anything on the product and do not apply excessive pressure to the product. Al-

Main Parts with Limited Life
• Hard Disk Mounted Products
The operational warnings are listed below.
• Do not move, shock and vibrate the product while the power is turned on.
Reading or writing data in the hard disk unit is performed with the memory disk turning at a
high speed. It is a very delicate process.
• Store and operate the products under the following environmental conditions.
An area with no sudden temperature changes.
An area away from shock or vibrations.
An area free from moisture, dirt, or dust.
An area away from magnets or an instrument which generates a magnetic field.
• Make back-ups of important data.
The data stored in the disk may become damaged if the product is mishandled. The hard disc
has a limited life span which depends on the operational conditions. Note that there is no
guarantee for any loss of data.

6243/44 DC Voltage Current Source/Monitor Operation Manual
Caution-1
SAFETY PRECAUTIONS FOR THE 6243/44
Confirm all of the following points before connecting the 6243/44 and the DUT to prevent destruction of the
DUT due to an overload of voltage or current:
• The 6243/44 is in the standby mode. (OPERATE lamp is off.)
• No error or failure indication is displayed.
• The 6243/44 is grounded. (The ground pin of the power cable is grounded.)
• When using an ADC CORPORATION manufactured test fixture, connecting the INTERLOCK ter-
minal to the LID SIGNAL on the test fixture makes it possible to set the output to standby status by
opening and closing the lid.
When mounting the 6243/44 in a rack
• Make sure that the rack does not topple over if the 6243/44 is off balance.
• Be careful that the rack does not topple over when the slide rail is pulled out.
When the 6243/44 is used in the TR6143 Mode 1
The voltage limiter of the current source function only operates using the same polarity as that of the
source.
When the current source value is set to +0 A in the no-load status, or when negative current is generated
due to an error, the output terminal may deliver a negative supply voltage. (6243; -130 V, 6244; -26 V)
If these conditions pose a problem, use one of the following procedures.
• Set the value of current source to 10 counts or higher at all times.
• Use the Original Mode.
• Use the TR6143 Mode 2.
(In TR6143 Mode 2, the GPIB commands are the same as in TR6143 Mode 1. However, the hard-
ware configuration is the same as the 6243/44 so the voltage limiter operates using both polarities.)
