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
This instrument is a waveform measuring device that monitors and measures
electrical signals. Do not use this instrument for anything other than as a waveform
measuring device.
Check the Physical Appearance
Do not use the instrument if there is a problem with its physical appearance.
Use the Correct Power Supply
Before connecting the power cord, ensure that the source voltage matches the
rated supply voltage of the DLM2000 and that it is within the maximum rated
voltage of the provided power cord.
Use the Correct Power Cord and Plug
To prevent the possibility of electric shock or fire, be sure to use the power cord
supplied by YOKOGAWA. 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. Additionally, do not use the power cord
supplied with this instrument with another instrument.
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 comes with the instrument is a three-prong type
power 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 gasses 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 item under
measurement or to an external control unit. Before touching a circuit, turn off its
power and check that it has no voltage. To prevent the possibility of electric shock
or an accident, connect the ground of the probe and input connector to the ground
of the item being measured.
