EXTERNAL DC ADAPTER User’s Manual
the power is automatically switched to the AC power.
In such cases, a switching time of approximately 1 sec
is required to switch the power inside the oscilloscope.
If the AC power is connected while the DC power is
being used and the DC power is turned OFF (or the
cable is disconnected) at the same time, the power
supply is interrupted during switching time and the
oscilloscope operation is completed abnormally,
causing the oscilloscope to be faulty or data to be
corrupted.
4. Turn on the ON/STANDBY switch provided at the lower left on
the front panel of the WaveSurfer oscilloscope.
The oscilloscope will start operating.
NOTE 5 When the DC adapter is used together with a
vehicle-installed battery, do not start the engine while
the WaveSurfer is operating.
Failure to observe this may result in a breakdown in the
WaveSurfer or corruption of data.
When the engine is started (while a cell motor is used),
the power to the WaveSurfer may be shut down due to a
temporary drop of the battery voltage.
NOTE 6 When the DC adapter is used together with a
vehicle-installed battery, be careful with the charge
status of the battery.
If you keep the WaveSurfer in operation for a long time
while the vehicle engine is stopped, the battery power
will be consumed and you may not start the engine or
the battery may deteriorate.
