Safety Precautions
Safety Precautions
When using the instrument for the first time, make sure to read the “Safety
Precautions” given on pages iv and v.
Do not remove the cover
Do not remove the cover from the instrument. Some sections inside the instrument
have high voltages that are extremely dangerous. For internal inspection or
adjustment, contact your nearest YOKOGAWA dealer as listed on the back cover of
this manual.
Abnormal behavior
Stop using the instrument if there are any symptoms of trouble such as strange odors
or smoke coming from the instrument. If these symptoms ocurr, immediately turn
OFF the power and unplug the power cord. Contact your nearest YOKOGAWA
dealer as listed on the back cover of this manual.
When the cooling fan stops
If error code 906 appears on the display, the cooling fan is stopped. Immediately turn
OFF the power switch. From the rear panel, check for and remove any foreign object
that may be obstructing the cooling fan. If error message 906 appears when you turn
ON the power switch again, it is probably a malfunction. Contact your nearest
YOKOGAWA dealer as listed on the back cover of this manual.
Power cord
Nothing should be placed on top of the power cord. The power cord should also be
kept away from any heat sources. When unplugging the power cord from the outlet,
never pull by the cord itself. Always hold and pull by the plug. If the power cord is
damaged, check the part number indicated on page ii and purchase a replacement.
