2.6 Turnng ON/OFF the Power Swtch
CAUTION
Check the following points before turning ON the power switch.
• The power cord/wires are connected correctly to the recorder.
• The recorder is connected to the correct power supply (see section 2.5).
The power switch is located inside the door at the lower right.
The power switch is a push button. Press once to turn it ON and press again to turn it
OFF.
When the power switch is turned ON, a self-diagnosis program runs for a few seconds,
and the recorder is ready for operation.
Note
• If the input wires are connected in parallel with other devices, do not turn ON/OFF the power
switch of the recorder or another device during operation. This can have adverse effects on
the measured values.
• If nothing is displayed when the power switch is turned ON, turn OFF the power switch
and check the points listed above one more time. After checking the points, turn ON the
power switch again. If the unit still does not work, it is probably malfunctioning. Contact your
nearest YOKOGAWA dealer for repairs.
• If an error message is displayed on the screen, take measures according to the description
in chapter 10, “Troubleshooting.”
• Turn ON the power switch, let the recorder warm up for at least 30 minutes, and then start
the measurements.
