Installation
4.1 Mains operation
Only power the device from the mains using an external mains adapter connected to the 12 V extra-low voltage jack. A
suitable adapter with connecting cable is included in delivery (see “External power supply”).
IMPORTANT!
Always disconnect the device from the power supply when disassembling the device (e.g. replacing
batteries).
4.2 Battery opreation
4.2.1 Replacing the battary
Only the manufacturer or service technicians authorised by the manufacturer may replace the internal battery. The
manufacturer’s guarantee will be void if the housing of the measuring receiver is opened by anyone else.
4.2.2 Battery management
The device has internal battery management, which optimises the charging and discharging of the battery. The battery
begins to charge as soon as the device is connected to the mains or an external voltage supply. The device starts in
charging mode if it is not being used; during this time only the OSD window on the top left is shown with the text
“Charging BATT” and the battery symbol.
The display screen turns off after a minute. Pressing any button turns the display back on. If the device is operated in
measuring mode, the charging current may be reduced somewhat depending on the operating status, causing the
charging process to take longer. When the battery is being charged, the “charge” LED lights up red. Once the battery is
fully charged, the internal battery management switches to maintenance charging and the “charge” LED turns green.
The device also has a charge status indicator. A status bar in the frequency window indicates the remaining charge of
the battery at all times. If the battery charge becomes critical, the word “low” appears in red next to the bar. You can
still complete the current measurement, but the battery should then be recharged as soon as possible. The device
shuts down automatically to prevent total discharge.
4.3 Operation using an external power supply
In addition to using the battery, you can run the device on external direct current supplied by the mains adapter or the
cigarette lighter adapter in a vehicle, for example. Direct current is fed via the extra-low voltage jack on the bottom
section of the device. The external voltage supply must be in the range of 11 V to 15 V. The maximum current con-
sumption is 2.5 A. When the device is supplied with appropriate voltage, the “charge” LED on the front side of the
device lights up.
4.4 Fan control
A small, in-built fan ensures that the electronic components are well ventilated. This fan is controlled by the micropro-
cessor using a temperature sensor.
16 Chapter 04 – Installation
10911 V01.10
4.5 Turn on
The device processor requires approx. 5 seconds to boot up. During this time, the “charge” LED lights up yellow.
Afterwards, a display appears on the screen.
4.6 Adjust volume, image brightness, color temperature and saturation
Mit der Taste AV SET wird je einen Balken für die Bildhelligkeit und für die Lautstärke auf dem Bildschirm eingeblendet.
These can then be set with the arrow keys. This function is not possible in some operating states such as level measure-
ment. With the MODE button, the function of the lower bar can be changed from image brightness to color tempera-
ture and further to color saturation.
This allows the color representation of the display to be optimized and the set values are stored in the non-volatile
memory. By pressing AV SET or ESC again, the bars are hidden and the arrow keys have their original function again.
When the AV menu is called up again, the lower bar again shows the set image brightness.

Chapter 06
Measuring range
6.1 Frequency input
Frequencies are displayed in the frequency window. Enter the value of the frequency in MHz or GHz (see below). Set
the desired frequency using the number keys or arrow keys. The decimal unit can be changed from 0 to 9 by pressing
the Up and Down arrow keys when the cursor is on that unit. Use the ←and →keys to move the cursor left and right.
Pressing a number key enters the corresponding value in the lowest decimal unit. All the positions above are set to
zero. Every time an additional number is entered, the existing value shifts a position to the left and the latest entry is
used for the lowest unit. Confirm by pressing ENTER. If the value entered is not within the valid range, it will be limited
to the corresponding minimum or maximum value.
After that, the receiver is tuned and the actual measured values are displayed.
Press the ESC key, an arrow key or a number key to end the measurement procedure. A new frequency can be set as
described above.
6.1.1 IF input
To change the device to IF input, select
MODE > Frequency input mode > SAT-IF. The frequency window displays SAT-IF (MHz).
6.1.2 RF input
To change the device to RF input, select
MODE > Frequency input mode > HF[GHz]. The frequency window displays SAT-RF (GHz).
This function serves to incorporate frequency conversion in an LNB from the transponder frequency (RF) to the first SAT
IF, depending on the LNB oscillator frequency (LO).
For Ku band LNBs: ZF = HF − LO. The device calculates: HF = ZF + LO.
For C band LNBs: ZF = LO − HF. The device calculates: HF = LO − ZF.
6.1.2.1 Ku-band
The device provides two user-defined LNB oscillator frequencies for RF inputs in the Ku band. These can be changed
under MODE > Settings > LNB-Frequencies > Ku low band (Ku high band) within the range of 9,000 to 11,000 GHz.
The factory presettings are 9,750 GHz (low band) and 10,600 GHz (high band).
The device also provides three ways of using the two oscillator frequencies: Using the menu MODE > Settings > LO-

“Ku standard” (coupled to the LNB setting), “Ku LOLow” (low-band oscillator always incorporated regardless of LNB
setting) and
“Ku LOHigh” (the high-band oscillator respectively).
6.1.2.2 C band
The device provides one user-defined LNB oscillator frequency for RF inputs in the C band. This can be changed under
MODE > Settings > LNB-Frequencies > C band
within the range of 4,000 to 6,000 GHz. The factory presetting is 5,150 GHz. To use the LNB oscillator frequency, select
the “C band” menu item via MODE > Settings > LO-Allocation.
If the device is operating with RF input, the LO used is shown in the frequency window with the abbreviations
»KuL« (LO for Ku low band),
