• This product generates high voltage. Be careful of electric shock and electric discharge.
• To prevent electric shock, remove rings, watches, and other metallic accessories and
jewelry before operation.
Connect Cables Correctly
This instrument can generate large voltage and current. If you do not connect the devices
correctly, not only will it damage the instrument or the target device, it may also lead to electric
shock or fire. Be careful when you connect the cables, and be sure to check the following
points.
Before output (before turning on the output), check that:
• Cables have been connected to the instrument’s output terminals correctly.
Check that there are no voltage output cables that have been connected to the current
terminals.
Check that there are no current output cables that have been connected to the voltage
terminals.
• Cables have been connected to the target device correctly.
Check that there are no short circuits between voltage terminals or between the cables
connected to the voltage terminals.
• The cables are connected firmly to the current terminals.
• There no problems with the current terminals and the crimping terminals, such as the
presence of foreign substances.
During output (never touch the terminals or the connected cables when this instrument is on),
check that:
• There no problems with the current terminals and the crimping terminals, such as the
presence of foreign substances.
• The current terminals are not abnormally hot.
• The cables are connected firmly to the current terminals.
The terminal connections may become loose over time. If this happens, heat may be
generated due to changes in contact resistance. If you are going to take measurements
using the same setup for a long time, periodically check that the cables are firmly
connected to the terminals. Be sure to turn off both this instrument and the target device
before you check the connections.
After output (immediately after the output is turned off)
After you output a voltage or current, voltage may remain for some time even after you turn
the output off. This residual voltage may lead to electric shock. Do not touch the terminals
immediately after you turn the output off. The amount of time that voltage remains varies
depending on the target device.
