First Time Operation
(38) CURSOR
- Center biased lever.
The active cursor line (in track mode: both lines) can be
shifted in the required direction, until the graticule limits
are reached. The directions are marked on the front panel
and depend on the selected measurement (
∆∆∆∆∆
V,
∆∆∆∆∆
t
or
1/
∆∆∆∆∆
t
= f
).
Which of two shift speeds is used, depends on how far
the
CURSOR
knob is pressed. With slight knob pressure
the cursor line(s) moves slowly. If the knob is pressed to
the full extent the cursor moves fast. If the knob is
released it automatically reverts to the center position
and the cursor shift stops.
(39) CAL
. - Pushbutton and concentric socket.
A squarewave signal of 0.2Vpp ±1% is available from
the socket for probe adjustment purposes.
The signal frequency depends on the pushbutton setting.
If the pushbutton is released it is approx. 1kHz and can
be switched over (depressed) to approx. 1MHz. The pulse
duty factor may deviate from 1:1 and the frequency is
not calibrated.
(40) CT
- Pushbutton and banana jack. Pressing the push-
button switches the instrument over from oscilloscope
to component test mode and vice versa.
In component test mode, all controls are deactivated with
the exception of the
CT
button,
AUTO SET (2)
and
INTENS
(4)
. All LEDs except
”A”
or
”RO”
(associated
with the
INTENS
knob) are dark. The readout displays
only
”CT”
in this condition.
One test lead is connected to the CT socket. The second
test lead uses the ground socket
(29)
. Please note
”Component Tester”.
The maximum test voltage is approx. 20Vpp under open
circuit conditions, while the max. test current under short
circuit condition is approx. 20mApp.
Menu
The instrument software contains several menus. The controls
regarding the menus are described under item
MENU (34)
in
section “Controls and Readout”.
The following menus, submenus and items within the
submenus are available:
1.
MAIN MENU
1.1 CALIBRATE
Information regarding this can be found in the section ”Service
Instructions” item ”Adjustments”.
1.2 SETUP
This menu allows changes to the default settings regarding
the instrument behavior during operation. The SETUP menu
contains the submenus
”MISCELLANEOUS”
and
”FACTORY”
.
1.2.1 MISCELLANEOUS
contains:
1.2.1.1 CONTROL BEEP ON/OFF
In OFF condition the acoustic signals actuated by
the control limits are switched off.
Note:
The default setting is ON. If different conditions are
required the setting must be performed each time
after switching the oscilloscope on.
1.2.1.2 ERROR BEEP ON/OFF
Acoustic signals indicating faulty control operation
are suppressed in OFF condition.
Note:
The default setting is ON. If different conditions are
required the setting must be performed each time
after switching the oscilloscope on.
1.2.1.3 QUICK START ON/OFF
In condition ON the HAMEG logo and the menus
will not be displayed after switching the instrument
on. Then the instrument is quickly ready for operation.
1.2.1.4 TRIG SYMBOL ON/OFF
In most of the Yt (time base) modes the readout
displays a trigger point symbol which will not be
displayed in condition OFF.
1.2.1.5 DC REF ON/OFF
If ON is selected and Yt (time base) mode is present,
the readout displays a ground symbol (
⊥
). This symbol
eases the evaluation and determination of DC
contents by indicating the 0 Volt reference position.
1.2.1.6 INPUT Z ON/OFF
In ON condition the TRIG.EXT. socket serves as an
unblanking input.
1.2.1.7 MEAN VALUE ON/OFF
The mean value display is activated in the readout if
ON is selected and cursor line measurement is
switched off. For further information please note
section “Mean Value Display”.
1.2.2 FACTORY
Attention!
Submenus are available only for HAMEG authorized
service workshops
First Time Operation
The following text assumes that the
”SAFETY”
section of
this manual has been read carefully and understood.
Each time before the instrument is put into operation check
that the oscilloscope is connected to protective earth. For that
reason the power cable must be connected to the oscilloscope
and the power outlet. Then the test lead(s) must be connected
to the oscilloscope input(s). Check that the device under test
is switched off and connect the test lead(s) to the test
point(s). Then switch on the instrument and afterwards the
device under test.
The oscilloscope is switched on by depressing the red
POWER
pushbutton. After a few seconds the
HAMEG
logo and the
instrument software release is displayed on the screen. As
long as the
HAMEG
logo is visible different internal checks are
