The connector housing is connected to the instrument housing
and thus to safety ground. The ring around the connector is the
probe identification contact, no voltage may be applied here.

LC0 ... LC3 LOGIC PROBE
(multi pin connector)
At the connector a logic probe for 4 logic channels (LC0 to
LC3) can be connected. The logic channels are available only
in digital mode. The connector serves as an input as well as a
supply voltage output for the voltage comparators inside the
logic probe.
STOP
Attention!
The logic channels and the related settings can
only be activated and displayed if the optional probe
HO2010 is connected.
Some pins are connected galvanically to the instrument housing
and thus to safety ground (PE). No voltages must be applied at
the multi pin connector.

PROBE ADJ.
(connector)
The square wave signal from this socket has an amplitude of 0.2
V
pp
and serves for frequency compensation of 10:1 probes. The
signal frequency can be determined in the menu “Utilities“ that
is present after pressing PROBE ADJ-pushbutton
41
.
Further information may be found in the section ”Probe adjust-
ment and use“ in the chapter ”Operation and presettings“.
41
PROBE ADJ
(pushbutton)
Pressing this pushbutton opens the menu “Utilities“.
41.1 COMP.Tester On Off
Component Tester mode (On) is only possible in analog mode
which is automatically set.
In this mode only a shorter trace, “Component Tester“ and
measurement parameter (test voltage and maximum test
current) are displayed. The sockets marked “COMP. TESTER“
serve as inputs. Pressing the function key “off“ switches back
to the last used operating conditions.
41.2 Calibrator
The function keys 1 kHz and 1 MHz enable the selection of the
square wave signal frequency available at the PROBE ADJ
connector.
41.3 Information
This function key opens the item Utilities Information which of-
fers information about the oscilloscope, as well as the available
interface at the rear of the oscilloscope.
41.4 USB Stick
If NONE is displayed, no USB fl ash drive is connected at the
“USB Stick“
43
. After connecting a USB fl ash drive NONE is
replaced by hints on the submenus Save and Recall that can
be opened by pressing the assigned function keys.
When the menu Utilities is not displayed, it opens automati-
cally when a USB fl ash drive is connected. with the USB Stick
connector
43
.
41.4.1
USB Stick Save
– Front Panel
(current oscilloscope parameters)
The current parameters are saved on the USB fl ash drive
by pressing the function key “Save as SET00000“. After-
wards the display shows the name of the next memory (e.g.
SET00001) in which parameter can be saved.
– Screenshot
Screenshot can be saved in bit map format by pressing the
function key “Save as SCR00000“. Afterwards the display
shows the name of the next memory (e.g. SCR00001) in
which bit map data can be saved.
– Wave
After the selection of “Source“ (channel) and “Type“ (REF =
reference memory; CSV (data format) = comma separated
value; ASC (ASCII) or BIN (binary format) the sector “Save
as WAV00000 shows the memory name in which the data
are stored. Afterwards the display shows the name of the
next memory (e.g. WAV00001) in which wave form data can
be saved.
41.4.2
USB Stick Recall
– Front Panel
(stored oscilloscope parameters)
Press “Recall“ if only one parameter set is stored in the
USB fl ash drive.
If more then one parameter set is stored in the USB fl ash
drive, the function key “File“ together with the rotary encoder
symbol are displayed. Pressing “File“ opens a “Selection“
box opens where different memory place numbers can be
selected by aid of the INTENS knob
2
.
Press the “Recall“ function key to copy the selected signal
(wave) into the selected oscilloscope reference memory.
– Reference Memory X
(rotary encoder symbol)
Press the “Reference“ function key and turn the INTENS
knob
2
to select one of 9 oscilloscope reference memories
into which the signal (wave) stored in the USB fl ash drive
shall be copied.
If more than one signal (wave) is stored in the USB fl ash
drive, the function key “File“ together with the rotary encoder
symbol are displayed. Pressing “File“ opens a “Selection“
box where different memory place numbers can be selected
by aid of the INTENS knob
2
.
Press the “Recall“ function key to copy the selected signal
(wave) into the selected oscilloscope reference memory.
42
COMP. TESTER
(sockets)
Both 4 mm diameter sockets serve as a two pole input for
component test. Further information can be found under section
“Component Tester“.
43
USB Stick
(USB fl ash drive connector)
This connector is designed for direct connecting an USB fl ash
drive without an USB cable.
After a USB fl ash drive has been connected, the LED in the USB
fl ash drive briefl y blinks and the menu Utilities“ opens. Further
information can be found under PROBE ADJ 41.4: USB Stick.
44
MENU OFF
(pushbutton)
Switches the menu display off or one step back in the menu
hierarchy.
