3 A quick introduction
The following chapter is intended to introduce you to the most
important functions and settings of your new oscilloscope in
order to allow you to use the instrument immediately. The in
-
ternal calibrator signal output is used as the signal
source, so
you will not need any additional instruments for the first steps.
3.1 Setting up and turning the instrument on
Fold out the feets completly so the display will be inclined
slightly upwards. (See chapter 1.2 for positioning) Plug the po
-
wer cord into the rear panel connector. The instrument will be
turned on by switching on the main power switch on the back
and pushing the key On/Off
1
on the front panel. After a few
seconds the display appears, and the oscilloscope is ready for
measurements. Now press the key AUTOSET
15
for at least 3
seconds.

3.2 Connection of a probe and signal capture
Take one of the probes delivered with the instrument, detach
the protective cap from the top. Apply the compensation box to
the BNC connector of channel 1 and turn the black knob CW
until it latches positively.
Passive probes be compensated prior to first use.
Please refer to the probe manual for the proper
compensation procedure. Place the probe in the
appropriate position on the ADJ. output such that
the tip will be accepted by the hole of the right out-
put while the ground connection is made to the left
output, as shown in Fig. 4.3 in chapter 4.

To start the self alignment for the
logic probe, it is necessary that
the logic probe type HO3508 is connected to the HMO. It is im
-
perative that the bit connectors are not connected. To start the
process, select the menu item
LOGIC PROBE SELF ALIGNMENT
.
The process is similar to the basic instrument alignment but it
only takes a few seconds.
