1. PREFACE
This chapter describes the accessories, operating environment, precautions, and operating check for person-
nel who operate the 6247G/6247C. Read this manual before using the 6247G/6247C.
1.1 Product Overview
The 6247G/6247C is a DC Voltage Current Source/Monitor capable of evaluating high-voltage semiconduc-
tors and LED luminaires that demand high efficiency and low power consumption with its wide ranging
source and measurement functions.
The 6247G/6247C provides high sensitivity with 41/2-digit source resolution and 51/2-digit measurement res-
olution. In addition, it is equipped with not only the various types of sweep functions but also the pulse mea-
surement function with the minimum pulse width of 50 s. By using these functions, the 6247G/6247C can
be widely used as ideal SMU for evaluating or testing semiconductor and other electronic components.
• Source and measurement: -15 V to +250 V, 0 to 320 mA
• Voltage range: 5 V, 50 V, 250 V
• Current range: 3 A to 300 mA
• Display digits Source: 41/2Measurement: 51/2
• Voltage resolution Source: 100 V Measurement: 10 V
• Current resolution Source: 100 pA Measurement: 10 pA
• Voltage source current measurement (VSIM)/Current source voltage measurement (ISVM)
• Voltage source voltage measurement (VSVM)/Current source current measurement (ISIM)
• Sink-enabled bipolar output
• Minimum pulse width: 50 s
• Linear, 2-slope linear, fixed, random sweep functions for characteristic test
• Detection functions such as limiter (compliance), overload, and overheat
• Synchronized operation function by combining two or more 6247G/6247C units
• GPIB and USB (6247G) or RS-232 and USB (6247C) for integrating an automated measurement sys-
tem

1.3 Optional Accessories
The 6247G/6247C optional accessories are listed below. Specify the part number when ordering.
As the rack mount set is not rigid enough to support the instrument by itself, use angle bars to mount the
6247G/6247C on the rack mount set. Contact an ADC CORPORATION sales representative for rack setup
and other technical support.

1.4 Operating Environment
This section describes the required environmental and power supply conditions.
1.4.1 Environmental Conditions
The 6247G/6247C must be installed in an environment meeting the following conditions:
• Ambient temperature: 0ºC to +50ºC (temperature range for operation)
-25ºC to +70ºC (temperature range for storage)
• Relative humidity: 85% or lower (without condensation)
• Location not subject to corrosive gasses
• Away from direct sunlight
• Dust free
• Vibration free
• Noise free
The 6247G/6247C is designed with full consideration given to the noise contained in the AC power
line. Nevertheless, it is recommended that the 6247G/6247C be used in an environment with as little
line noise as possible.
If line noise is unavoidable, use a noise filter.
• Positioning of the 6247G/6247C
A cooling fan is located on the rear panel and vents are located on the side panels. Do not block the
fan and vents. Leave at least 10 cm of free space between the rear panel and the wall. Also, do not
position the 6247G/6247C with the rear panel facing down.
Obstructing the vents will cause the internal temperature to rise, possibly causing faulty operation.
• Mounting in a rack
Ensure that exhaust air from other devices is not directed at the vents on the side of the 6247G/6247C.
To prevent the temperature in the rack from rising, install a heat sink fan.

1.4.3 Changing Power Voltage, and Checking and Replacing Power Fuse
The 6247G/6247C power voltage can be changed manually.
This section describes the procedure for changing the power voltage, and checking and replacing the
power fuse.
CAUTION:
1. If the power fuse has opened, a problem occurred in this instrument. Contact an ADC CORPORATION sales
representative.
2. Always use the same fuse type and rating to prevent fire.
1. Remove the fuse holder assembly from the rear panel.
Push on each side of the fuse holder assembly with a flathead screwdriver ( )
and pull the assembly out ( ).
2. Remove the voltage selector from the assembly.
3. Rotate the voltage selector until the correct voltage appears in the window.
