(e) Starting Up the Oscilloscope
After making necessary connections, start up the oscilloscope
following the steps below.
1. Set the input voltage to the DC adapter.
NOTE 1 Use a battery with the rated output voltage of 12 Vdc or
24 Vdc.
NOTE 2 Set the output voltage of the DC power unit in the
range between 12 Vdc and 28 Vdc.
2. Connect to the battery or turn on the output switch of the DC
power unit.
NOTE 3 The standby time until a voltage of 23.5 V is output
after the DC power has been supplied is approximately
5 sec.
3. Turn on the POWER switch of the DC adapter. (See Figure 12
below.)

Now the oscilloscope can operate with the voltage supplied from
the battery (or other DC power unit) and the DC adapter.
NOTE 4 If a commercial AC power is supplied through the AC
power cord connected to the rear of the oscilloscope,
the oscilloscope operates giving a higher priority to the
AC power supply.
When both the AC power and DC power are connected,
the AC power is used as drive power. However, if the
AC power is interrupted, the power is automatically
switched to the DC power. Additionally, if the AC
power is connected while the DC power is being used,
