Safety Summary
To ensure thorough understanding of all functions and to ensure efficient use of this instrument, please read the
manual carefully before using. Note that ADC Corporation (hereafter referred to as ADC) bears absolutely no
responsibility for the result of operations caused due to incorrect or inappropriate use of this instrument.
If the equipment is used in a manner not specified by ADC, the protection provided by the equipment may be
impaired.
• Warning Labels
Warning labels are applied to ADC products in locations where specific dangers exist. Pay
careful attention to these labels during handling. Do not remove or tear these labels. If you have
any questions regarding warning labels, please ask your nearest ADC dealer. Our address and
phone number are listed at the end of this manual.
Symbols of those warning labels are shown below together with their meaning.
DANGER: Indicates an imminently hazardous situation which will result in death or serious
personal injury.
WARNING: Indicates a potentially hazardous situation which will result in death or serious
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
injury.
• 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.
• If there is any abnormality such as abnormal heart, smoke, smell or noise, immediately stop
using the instrument, turn off the power and disconnect the plug from the outlet.

Safety Summary
Safety-3
FOE-ANZENA01
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.
• Precautions when Disposing of this Instrument
When disposing of harmful substances, be sure dispose of them properly with abiding by the
state-provided law.
Harmful substances: (1) PCB (polycarbon biphenyl)
(2) Mercury
(3) Ni-Cd (nickel cadmium)
(4) Other
Items possessing cyan, organic phosphorous and hexadic chromium
and items which may leak cadmium or arsenic (excluding lead in
solder).
Example: fluorescent tubes, batterie

1. PREFACE
This chapter describes the accessories, operating environment, precautions, and operating check for
personnel who operate the 6253. Read through this manual before using the 6253.
1.1 Product Overview
The 6253 is a DC Voltage Current Source/Monitor that offers high sensitivity with 51/2-digit source
resolution and 61/2-digit measurement resolution, as well as various sweep functions and a pulse source
function with a minimum pulse width of 25 s. It can be widely used as power source for evaluating
semiconductors and electronic components in research and development and as power source for
characteristic evaluation systems.
The 6253 characteristics are described below.
• Source and measurement 2 A at 32 V
1 A at 64 V
0.5 A at 110 V
See Figure 1-1, “Output Range.”
• Voltage source/measurement range 300 mV to 100 V
• Current source/measurement range 3 A to 2 A
• Display digits Source: 51/2Measurement: 61/2
• Voltage resolution Source: 5 V Measurement: 100 nV
• Current resolution Source: 50 pA Measurement: 1 pA
• Voltage source current measurement (VSIM)/Current source voltage measurement (ISVM)
• Voltage source voltage measurement (VSVM)/Current source current measurement (ISIM)
• Monitors source values of DC voltage or current.
(Measured separately from the measurement function)
• Sink-enabled bipolar output
• Minimum pulse width 25 s
• Linear, fixed, random, multi-slope linear and log sweep functions for characteristic test
• Detection functions such as limit (compliance), oscillation, overload, and overheat
• Synchronized operation function by combining two or more 6253 units
• USB and GPIB as standard and optionally LAN and RS232 available
• Improved operability with a color display and a numeric keypad
