Failure to comply with the precautions below could lead to injury
or death or damage to the instrument.
WARNING
Use the Instrument Only for Its Intended Purpose
The 2553A is a DC calibrator that sources DC voltage, DC current, and resistance. It also
sources thermoelectromotive force and resistance that simulate those of a temperature
sensor. Use the 2553A only for these purposes.
Check the Physical Appearance
Do not use the instrument if there is a problem with its physical appearance.
Use the Correct Power Supply
Make sure that the power supply voltage matches the instrument’s rated supply voltage and
that it does not exceed the maximum voltage range of the power cord to use.
Use the Correct Power Cord and Plug
To prevent the possibility of electric shock or fire, be sure to use the power cord for the
instrument. The main power plug must be plugged into an outlet with a protective earth
terminal. Do not invalidate this protection by using an extension cord without protective earth
grounding. Further, do not use this power cord with other instruments.
Connect the Protective Grounding Terminal
Make sure to connect the protective earth to prevent electric shock before turning on the
power. The power cord that you can use for the instrument is a three-prong cord. Connect the
power cord to a properly grounded three-prong outlet.
Do Not Impair the Protective Grounding
Never cut off the internal or external protective earth wire or disconnect the wiring of the
protective earth terminal. Doing so may result in electric shock or damage to the instrument.
Do Not Use When the Protection Functions Are Defective
Before using this instrument, check that the protection functions, such as the protective
grounding and fuse, are working properly. If you suspect a defect, do not use the instrument.
Do Not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable gases or vapors. Doing so is
extremely dangerous.
Do Not Remove the Covers or Disassemble or Alter the Instrument
Only qualified YOKOGAWA personnel may remove the covers and disassemble or alter the
instrument. The inside of the instrument is dangerous because parts of it have high voltages.
Ground the Instrument before Making External Connections
Securely connect the protective grounding before connecting to the target device or to an
external control unit. Before touching the target device, turn off this instrument and check that
there is no voltage or current being output.
