Power Up Operation
A self-test and calibration start automatically when the power switch is turned ON.
That lasts approximately 30 seconds. If the check results are satisfactory, the normal
waveform display screen will appear.
Note
• Allow at least 10 seconds before turning ON the power switch after turning it OFF.
• If self-test and calibration do not start when the power is turned ON, or if the normal
waveform display screen does not appear, turn OFF the power switch and check the
following points.
• That the power cord is plugged in properly.
• That the correct voltage is coming to the power outlet (see page 3-5).
• The settings are initialized (they are returned to factory default settings) by turning on the
power switch while holding down the RESET key. For details on the initialization of the
settings, see section 4.4, “Initializing Settings.”
If the instrument still fails to power up when the power switch is turned ON after checking
these points, contact your dealer.
• It takes several seconds for the startup screen to appear.
For Taking Accurate Measurements
• To ensure accurate measurements, allow the instrument to warm up for at least 30
minutes after turning ON the power switch.
• After warm-up is complete, perform calibration (see section 4.8). If Auto Calibration is
on, it will be executed automatically when T/div is changed and signal acquisition is
started.
Power Down Operation
The settings just prior to turning OFF the power (or when the power cord is unplugged)
are stored. Therefore, the next time the power is turned ON, waveforms are measured
using those settings.
Note
• A built-in lithium battery powers the memory that stores the settings. It has a life-span of
approximately 5 years when kept at an ambient temperature of 23°C. When the lithium
battery voltage falls below a certain level, a message is displayed on the screen (error 900)
when the power switch is turned ON. Whenever you see this message, you must have the
lithium battery replaced immediately. The user cannot replace the battery. Contact your
dealer to have a new battery installed.
• If you turn OFF the main power switch of the rear panel when the power switch of the front
panel is ON, the settings immediately before the power is turned OFF may not be stored
correctly. An error message (error 900) may appear on the screen the next time you turn
the power switch ON. This is not a malfunction. When turning the power OFF, turn OFF the
power switch of the front panel, and then turn OFF the main power switch of the rear panel.
