Turning ON/OFF the Power Switch
CAUTION
Do not turn the power ON or OFF when the Zip drive is installed, as this
could damage the drive. To avoid damaging the Zip drive, remove it
before turning the power ON or OFF.
Items to be Checked before Turning ON the Power
Check that the instrument is installed correctly as instructed in section 3.2, “Installation.”
Check that the power cord is connected correctly as sown in section 3.3, “Connecting the
Power Cord.”
Turning the Power ON/OFF
POWER switch: The power is turned ON and OFF alternately as the switch is pressed.
OFF ON
Note
• With the DC Power Model, if the main power is ON but the power does not turn on even if you
turn on the power switch, the circuit breaker on the rear panel may be tripped. Reset the
circuit breaker by following the procedure in section 15.5, "Resetting the Circuit Breaker."
• With the DC Power Model (with the -DC power supply specification), a shutdown may occur if
the power supply voltage exceeds 19 VDC or falls below 9.5 VDC. In case of a shutdown,
power cycle the unit using the power switch on the front panel (turn the power OFF, wait at
least 10 seconds, then turn the power back ON again).
If the instrument still fails to start, turn OFF the power switch on the front panel, turn OFF the
main power switch on the rear panel, then wait 10 seconds or more and turn the power back
ON again.
Response at Power ON
Self test and calibration start automatically when the power switch is turned ON. If the
check results are satisfactory, the normal waveform display screen will appear.
Note
• Wait at least 10 seconds after turning the power OFF before turning it back ON again.
• If calibration does not start when the power is turned ON, or if the normal waveform display
screen does not appear, check the following points.
• Check that the power cord is plugged in properly.
• Check that the main power switch is turned ON.
• Check that the correct voltage is being supplied from the AC outlet. (See section 3.3)
If there is still no power even after the above points have been checked, contact your nearest
YOKOGAWA representative as listed on the back cover of this manual.
