USEFUL SUGGESTIONS
1)
Thank you for choosing our measuring equipment, which is currently used and appreciated by the most important
Satellite Service Providers, Broadcasters and by many installers, because it is user friendly and provides complete
and accurate measurements. On our part, we will do our best to fulfil your requirements now and in the future.
2)
This is a new concept, quick user guide that is easy to consult. Select the function/measurement you need directly
from the index and on the respective page you will find all the relative menus.
3)
First of all please do not be concerned about the large quantity of menus found on the following pages; as this meter
is the most complete and advanced TV & SAT analyser available on the market, it is clear that it is capable of
carrying out many measurements. If you take a closer look you will notice that the menus are similar and basically
divided into two groups: MEASUREMENTS and SPECTRUM.
• MEASURE: analogue TV, COFDM, QAM & 8VSB digital TV, analogue Sat & QPSK digital Sat, Radio FM and
DAB.
• SPECTRUM: analogue TV, COFDM, QAM & 8VSB digital TV, analogue Satellite and digital QPSK satellite,
Radio FM and DAB.
4)
You will also see from a very early stage that all you have to do is store the various plans (PLAN) and programs
(PRG) (or ask your supplier to do it for you using the PC program, opt. SMART PRO), then choose the plan
(PLAN) and the program (PRG) needed each time. Select the spectrum function (SPECT) or the measurement
function (MEAS) and the meter will do everything automatically. Isn’t that great? We also suggest you photocopy,
cut–out and fill-in the tables on pages 108/109 and insert them in the transparent pocket in the instrument’s bag flap.
5)
Important: The instrument leaves the manufacturer with some default settings for test and demonstration purposes:
a) The instrument turns off after 5 minutes' inactivity, for transport by air.
This setting can be modified from the CONFIGuration menu (see page 12).
b) Check that you are using a meter with the correct channel plans for your country.
It is possible to modify this setting from the CONFIGuration menu (see page 12).
c) Some plans have been previously stored in the meter using one or more programmes in the various operation
modes, for example:

N.B. Dual function keys: when you see the words 2" or 10” (2 or 10 seconds) written above the keys, you should keep
the key pressed for 2 or 10 seconds to activate the second function.
All the remaining keys are just as easy to use and you can find complete descriptions on the last page (folded) of this
guide: we suggest you open it out for easier use.
key pressed for 2 seconds,
To use the numerical keyboard (SHIFT function), keep the
digit the number of the plan, channel, program, frequency etc. and press
again to confirm.
If you prefer, you can adjust/select all the various parameters by rotating the encoder knob.
7)
We promised you a user–friendly instrument, capable of doing everything by itself (or nearly); as you can see when
you are in measurement mode (MEAS) the upper part of the screen shows all the settings, for example: MODE–
PLAN–PRG–CHAN– FREQ–LNB– DiSEqC, etc. whereas the lower part of the screen shows all the measurements.
These can be seen individually or all together, by pressing the MORE MEAS key once according to the
measurement level you require (you can program levels 1–2–3 in CONFIG. See p. 12)
8)
If when navigating within the measurements you change any parameters, the program number will disappear.
Simply press PRG and reselect the previous program number by pressing the arrow keys to recall the previous
parameters, or if you want, press MEMORY to store the configuration you are using (see page 14).
9)
Now, please read the index on page 3, then carefully study the three most important menus to start:
• CONFIGURATION MENU
Page 12
• SPECIAL FUNCTION MENU
Page 13
• PROGRAM STORE MENU
Pages 14-15-16
You will learn the remaining functions in a few days by using the instrument. The first time you use the meter, we
strongly advise you connect it to a satellite dish or antenna which has already been installed and is operational and
where you know the channels and frequencies well.
10)
As you can see, in MEASUREMENT mode, the top left hand side of the display shows in which function you are
positioned, for example: QPSK. The upper part of the screen shows all the meter's settings (MODE), for example:
PROG–CHAN–FREQ etc., which can be directly recalled using the respective, direct function keys. The lower part
of the screen shows the POWER/LEVEL measurement and if you press the key MORE MEAS key once or twice
you can recall all the other measurements, which can be carried out. By pressing SPECTRUM, the meter instantly
shows, in the lower left-hand side of the screen, the mode you are in. (Remember that the spectrum can be automatic
or manual, see relative MENU).
11)
You can navigate in every screen using the UP and DOWN keys and in measurement mode using the direct function
keys. Please remember that this type of navigation is the same for all of your meter's menus and screens and that
when you are in digital mode, the response of the various menus becomes a little slower.
12)
Now go to the CONFIGURATION MENU, keep the SPECIAL key pressed for two seconds (see page 10). Select
your country's standard, the measurement unit you prefer and the TIMER setting (if you set "5 min" the meter turns
off after 5 minutes of inactivity and re-starts from the last measurement without losing data). You can adjust the
6
DM-14B & DM-14C User’s Guide
volume of the keys’ beep sound. To exit CONFIG. MENU press ESCAPE/MEAS. Please avoid using the
cancellation menu of the memory banks until you are confident with the use of the meter.
13)
Now let us take a look at the SPECIAL MENU (see page 13). To reach this menu, press the SPECIAL key once:
• SELF TEST: this is used if there are faults to see which parts are not communicating and to obtain the various
data information needed to inform the ROVER service (including the SW and FW versions and the instrument’s
serial number SN).
• A/V MONITOR: forces the video/audio input from the Scart socket (even without 12 V on the relevant PIN).
• TEST MONITOR: generates a test pattern (which can be used to test TV DC installations).
The video is available on pin 15 of the SCART socket.
• RF/IF INPUT SEL: selects the meter’s RF IN, either RF or IF: (38.0 / 38.9 / 45.75 MHz)
• VOLTMETER: measures the AC/DC voltage present at the RF connector.
• REFLECTOMETER: to measure the distance of a short circuit, interruption or mismatching in coaxial cables.
• AUTO SCAN (TV): to scan a channel plan for the search of analog or digital (COFDM) TV channels and
the relative automatic memorization inside the plan.
• FILE MANAGER: for file management (canalizations, plans, loggers, etc…) in the memory.
14)
BARS SCAN FUNCTION: This activates the bar chart graphics representation. In a display it is possible to see the
level/power of all the TV programmes stored in a plan. This function is useful for tilt adjustments and equalizations
in cable distribution networks and headends.
15)
NAVIGATION IN MEASUREMENT MODE (from pages 17 to 35) the various parameters can be quickly
changed using the direct function keys. We remind you once again that in this case the program number disappears.
At this point you have two options:
a) Press the programme key and select the same or another program number.
b) Press MEMORY and store the selected parameters previously modified (see page 14).
16)
NAVIGATION IN SPECTRUM MODE (from pages 36 to 47): the various parameters can be navigated using the
arrow and ENTER keys and are the same as those used by other more expensive, professional spectrum analysers.
The measurement dynamic range and the spectrum speed of this instrument are by far the best in this category and
despite everything, AUTOMATIC mode is very easy to use. Let’s take a look at some of the main functions:
• Reference level: this is the level of the reference line (the first line at the top of the grid) is adjusted
automatically to the carrier with the highest level inside the SPAN. When the SPAN varies, press SPECTRUM
twice to up-date and obviously you can also manually adjust it using the UP & DOWN keys. (N.B. The ref.
level corresponds to the attenuator of previous instruments). Remember that each time you change mode or turn
on the instrument again the ref. level automatically returns to the top of the ref. level (also in manual mode).
• Marker Frequency: shows the marker frequency (vertical dotted line); automatically in digital and analogue
SAT and it always positions in the centre of the carrier, whereas in analogue TV it always positions on the video
carrier. N.B.: The FREQUENCY MARKER is basically the meter's frequency tuning; in fact the marker can be
moved on the various carriers and when you go to MEAS mode you are automatically positioned on the same
frequency. If this frequency is exactly the same as one of the memorised channels, you will also see the relevant
channel, otherwise the display shows 3 lines (to remind you that something has been changed). Important: the
cursor also navigates outside the SPAN's limits, to the far left (start), to the far right (stop). If you release the
arrow keys every now and then, the tuned carriers are shown (the ones that were previously out of the SPAN
range). Naturally if you change from SPECT to MEAS, you can go directly to the tuned carrier/channel. For
easier viewing in Analogue TV and with 10 MHz SPAN, the centre of the channel will be positioned in the
centre of the display, whereas with the rest of the SPAN the marker is positioned in the display's centre.
• Marker level: shows the level of the signal measured by the marker (horizontal dotted line with crosses) and is
connected to the marker frequency position.
(N.B. When the MRK level line is on the highest carrier, it may be confused with the REF LEVEL line, the
highest line on the grid and become invisible).
• SPAN: this always shows the total bandwidth in MHz between the extreme left and extreme right of the display
(if you divide the value by 10 you can obtain the value of each square division).
• dB/div: shows the value in dB between each division of the horizontal grid. This is very helpful if you require a
wide dynamic range, e.g. 10 dB/div., to see noise AND interferences or a high resolution, 1 dB/div. For very
accurate SAT dish pointing both in SAT & TV. In this condition you can easily appreciate variations in dB
decimals.
• MODE: it shows which mode the instrument is working in (the various digital or analogue modulations, TV or
SAT etc.) and in SAT, you can also select the satellite dish pointing function; it automatically sets the spectrum
to easily point any satellite dish. To quit this function press ESCAPE/MEAS. MODE can also be used to select
the V.SAT function, providing a high resolution spectrum for V.SAT and SCPC installations.
May we remind you that when you press MENU you can also select:
• SPECTRUM: automatic or manual. If positioned on AUTOMATIC it always adjusts the SPAN and the dB/
so you can see the carrier, which is being examined.
• DEFINITION: high, medium, low. This increases the spectrum speed (to facilitate dish pointing).

PICTURE: spectrum with outlines only or full white
∆ MARKER: freq./level difference between two signals and C/N measurement
MARKER BW: to adjust filters, amplifiers, etc. and to measure digital power in SPECT mode “BW–PWR”.
MAX HOLD: peak memory. Maintains the max. peak reached during a series of measurements
DC at RF in: output power supply (5, 12, 15, 18, 24 V – OFF).
LNB L.O.: local oscillator.
BUZZER: ON/OFF activates an acoustic sound which varies with the signal level or digital satellite quality.
EMULATED COFDM/QAM DIGITAL TV MEASUREMENTS (DEMODULATED MEASUREMENTS:
COFDM supplied, QAM optional): These allow you to carry out perfect average power and C/N measurements,
provide a BER evaluation and the quality of the signal (FAIL–MARGINAL– PASS).
HOW THE EMULATED DIGITAL MEASUREMENT WORKS: The signal is measured in RF based on the
C/N measurement and multiplex flatness. Thanks to a series of special algorithms, defined and registered by
ROVER in co–operation with some UK DTG (Digital Terrestrial Group) engineers in 1998 and later optimised, it is
possible to provide a good signal evaluation in both cases of adjacent and non–adjacent channels (selectable n/f –
near/far) without demodulating the digital signal. The measurement accuracy is very high, except in rare cases of
interference completely hidden under the digital multiplex spectrum.
18) LNB-POL & DiSEqC: as you have already seen, there are two different settings, which make the instrument the
most complete and easiest to use in the world:
• LNB: OFF, VERT HIGH, VERT LOW, HORIZ HIGH and HORIZ LOW Polarization
• DiSEqC: off–a–b–c–d, the combination of these two parameters enables you to select the various multi-switches
with 4 cables “a”, 8 cables “b”, 12 cables “c”, 16 cables “d”.
19) You can obtain other very interesting spectrum functions with your instrument if you connect it to an optional noise
generator, for example the “CNG–80” or “CNG–70”:
• Scalar network analyser (wobulator), in “MRK BW” spectrum function, for the calibration and test of channel
filters, amplifiers, splitters, traps, outlets, coaxial cables and relevant VSWR or R.L. measurement of standing
waves ratio (with a reflect meter bridge).
• Coaxial cable reflect meter (“∆ MRK” spectrum function) to measure the distance of a short circuit or
interruption in coaxial cables (using a "T" connector and slide rule).
20) RESET: if the meter stalls and you are unable to turn it off, keep the ON key pressed for 10 secs and the instrument
will immediately restart. If you find that the instrument always blocks in the same situation, please contact the
manufacturer and you will be given, as an award, a year's service free of charge in addition to the standard one.
21) SOFTWARE UP–GRADE: As you well know, another excellent function of this meter is the possibility of up–
grading software free–of–charge via internet. To carry out this operation, consult Rover Instruments web site
(www.roverinstruments.com) and/or contact the service in your country.
22) START–UP MENU: this appears for two seconds every time you turn on your instrument and contains all the
information necessary for the service technicians in the case of repairs or software up-grades via internet (you can
find the same data in the SPECIAL, SELF TEST Menu).
23) We suggest turning off the meter when connecting or disconnecting the RS232 interface.
24) It is possible to store separate or mixed multi–standard plans (e.g. France/Europe or China/Hong Kong) according to
your requirements.
25) The instrument is supplied with interchangeable input connectors “F”, “BNC”, “IEC” or “N”.
26) If the TV signals are weak, or have lots of interference, and you have difficulty in tuning the TV pictures, exclude the
OSD and reactivate it, this operation should help you to tune TV pictures.
27) If the words on the screen do not tune during the frequency tuning of analogue TV and SAT programmes, briefly
remove the signal from the RF input and the words should stabilize.
28) If the instrument loses the vertical sync., with TV and SAT analogue pictures, press MENU and check that it is set to
the correct standard: 50 Hz PAL-SECAM and 60 Hz NTSC.
29) To eliminate the MENU words, press the MENU key.
30) Linear bar chart for level/power with memory & digital quality, e.g. QPSK, these are available in MEAS level 2.
8
DM-14B & DM-14C User’s Guide
N.B. With reference to fig. 8, the NETWORK name you can read in the centre to the right, e.g. NETNAME=SKY, is the
NET.ID table transmitted via satellite by the operator and which the instrument reads by extracting the information
from the MPEG data. However, the prog. name, read in the centre to the left under the word MENU, e.g. PROG
NAME: SKY1, is the one you, or your dealer, has pre-stored and can be varied only using a PC, opt. (see page 19).
N.B. When you activate MORE MEAS 3 (where available) and MENU, due to problems with space, the quality bar chart
and the level/power bar chart both respectively disappear. The white arrow, near to the quality bar chart, indicates
the minimum quality required to achieve a PASS in automatic tests.
32)
C/N MEASUREMENT
In some cases the C/N measurement of analog signals may vary with the level because when the level increases
some RF attenuators could be inserted. The automatic insertion of attenuators reduces the instrument’s sensitivity
and consequently reduces the C/N read on the screen, which will be less than the real one. To avoid this carry out
the following procedure:
• Select normal spectrum mode (without activating the C/N measurement)
• Fix the span at 200 MHz when in AN-SAT (analog satellite)
• Fix the span at 10 MHz (or 20 MHz) when in AN-TV (analog TV)
• Increase the REF-LEVEL (reference level) using the UP key, in 1 dB steps, until you see the noise lower by
approximately 10 dB
• If the noise goes under the line at the bottom of the screen, change the spectrum scale and set it at 10 dB/DIV (this
may occur in analog sat mode)
• Press MENU and select the ΔMRK (delta marker) activate the C/N select.
WARNING: make sure you do not press MEAS or any other key, because the attenuators will set using
standard values.
• Using the UP and DOWN keys bring the marker to the point where you want to measure the noise and read the
C/N value (which will correspond to the measurement filter bandwidth), in the window in the lower part of the
screen (ΔMRK C/N),
• May we remind you that when you measure the C/N in analog TV or SAT mode with the _MRK (without
specifying the C/N), the band correlation is not carried out automatically. In this case you should subtract 10 dB
from the measurement value if you are carrying our a satellite measurement, and 16 dB from the value for TV
measurements.
33)
C/N Measurements in emulated COFDM demodulation mode.
We suggest following these rules when carrying out emulated C/N measurements:
• Use C/N far when there are adjacent channels
• Always use C/N NEAR when there aren’t any adjacent channels
• If you are carrying out measurements on a head-end with selective filters and channel converters, only use the C/N
near measurement. In this case the C/N far measurement could measure a higher C/N than the real value.
To fix a C/N far or C/N near measurement, activate the configuration menu (see page 10 which contains the
configuration menu description).

DM-14B & DM-14C User’s Guide
DM-14B & DM-14Color Digimax
The DM-14B and DM-14Color meters allow you to visualise digital pictures of non-encrypted services (FREE-TO-AIR),
contained in the digital signals received at the RF input of the meter, in other words:
- Digital transponder transmitted via satellite with QPSK encryption,
- Digital multiplex transmitted via ether with COFDM encryption,
- Digital multiplex transimitted via cable with QAM encryption.
There are many services (TV or Radio programmes) inside a digital signal, such as the ones listed above. The
MPEG board allows you to see/listen to any of these services as long as they are not encrypted. To select one of
these services and obtain both the picture and the data of the Audio and Video PID, please refer to the
description of the “SERVICES” option in the MENU described on pages 22-27 and 34 of the manual.
It is important to note that when a digital signal is tuned and you want to see the picture of one of the services,
you should select a service using the “SERVICES” menu (see pages 22-27 or 34). Whenever a digital signal is
stored in a program in a memory plan, the visualization of the picture regarding a service contained within it
occurs only if this service was selected using the “SERVICES” menu. Consequently it is important to note that
every time you recall a digital program contained in any memory plan, the picture shown will be the one
belonging to the last selected service available for that transponder (see pages 22-27 and 34). If this selection is
not used, the board will not show any picture.
Example of a picture and relative data from the indicated transponder, obtained using the
“SERVICES” selection contained in the menu associated with digital signals.

SATELLITE DISH POINTING (SAT POINT function)
As this is a function which is used often and is, at the same time, facilitated by our automated high-resolution spectrum, we
thought we would dedicate a chapter to this subject (please also refer to the “QPSK” SPECTRUM).
a)
Activate SAT mode, analog or QPSK
(whichever you prefer).
or simply select a SAT programme, preferably in centre band, already pre–stored to receive the satellite and relative
band and polarization you require (e.g. Hot bird 13° E, VE l HI ↑, 11842,0 MHz).
b)
Press SPECTRUM.
c)
Press ENTER
(to quit MRK FREQ)
d)
Press the
key twice to go to MODE.
e)
Press
f)
Connect the LNB assembled on the dish to the RF IN of your meter.
g)
At this point the SAT POINT function has already automatically set the best SAT spectrum vision for you to carry out
satellite dish pointing, without having to touch your meter again (see fig.1).
, and press
once or twice to go to
Fig.1 LNB noise, without carriers
h)
Start pointing your dish (whose elevation has already been adjusted) in the correct direction until you can see some
carriers appear out of the noise and maximise them as shown in the two examples below (fig. 2 and 3). In theory the
satellite dish pointing is now complete; later we will see how to make it perfect and/or simplify the procedure using
some of the instruments special functions.
Fig.2 The carriers start to appear from the noise
Fig.3 Satellite dish pointing completed
11
DM-14B & DM-14C User’s Guide
i)
Now select 1 or 2 dB/DIV (in the lower right hand corner); in this configuration you have maximum spectrum
resolution, which allows you to perfect your dish pointing. If the carriers go over the reference level, increase it by 1
or 2 dB to see all the transponder peaks.

Press MENU again, remove the MAX HOLD and if necessary reselect HIGH definition, then adjust the cross

Go to measurement mode by pressing the MEAS key (level 1) and in the lower half of the screen you can see the
POWER value of the signal received (see fig. 6). Press the MORE MEAS key (level 2) and, if everything has been
stored well and you have pointed your satellite dish correctly, you should have all the measurements in the lower half
of the display, as shown in the example below (fig. 7).
N.B. By passing into MEAS you quit the SAT POINT function (and also the V.SAT function). To return, repeat the
operation from point b) to point e).
Press MORE MEAS again (level 3) and you can see the NETWORK and BOUQUET names as well as all the other
data and check to see if you are receiving the correct satellite/bouquet (N.B. Level 3 is the menu excluding the quality
and level bars, see fig. 8).

If, in the images shown in fig. 7 or 8 lines appear instead of measurements, it means that you have carried out the
wrong satellite pointing or storing procedure. Check everything once again and the first times always refer to a dish
that is already operational. In any case go to SPAN 50 MHz and see if there is a carrier exactly in the centre of the
marker (if there isn’t you are on the wrong satellite, or band, or polarization, or symbol rate, or frequency).
N.B. With reference to fig. 8, the NETWORK name you can read in the centre to the right (e.g. NETNAME=SKY) and the
other information are those transmitted via satellite and which the instrument obtains by extracting from the MPEG data.
However, the program name, read in the centre to the left under the word MENU, e.g. PROG NAME: SKY, is the one you,
or your dealer, has pre-stored and can be varied only using a PC, opt., see page 19. Adjust only using a PC or cancel all the
respective plans using the file manager DELETE, see pages 19 and 59.

PROGRAM STORE MENU (MEMORY)
2” to Store
The MEMORY MENU is very easy to use and is required to store programs. Basically, if you rotate the encoder, you
move the cursor (grey background) to the line that corresponds to the parameter to be adjusted, for example QPSK as
shown below.
Press the encoder and it will position on the value of the parameter/status you want to adjust/store. (See example under the
frequency line). Once the data required has been adjusted, rotate the encoder and press it again to quit. Rotate the encoder
again to go to STORE? or OVERWRITE? (STORE? appears automatically if the program number to be stored in the plan
has not yet been used, alternatively the word OVERWRITE? appears, to allow you to overwrite/replace an existing
program). Press encoder again to store the program. The program number increases one number at a time, e.g. it will go to
2 (only if the programs have never been stored before, if not go ahead one at a time manually). The cursor will go to the
parameter to be adjusted (e.g. frequency for the QPSK function shown below). If you do not need to modify any other
parameters, adjust only the frequency of the next program, for example 2. Press the encoder again to quit and using the
arrow keys go to STORE, press ENTER again to store and continue until you have completed all the channels/programmes
required.
N.B. You can store without navigating on STORE? by pressing MEMORY for 2 seconds.
It is possible to store up to 199 mixed programmes for each plan in each of the various modes of the instrument (e.g.
RADIO-TV-SAT-etc even with different standards, for example France/Europe or China/Hong Kong or Russia/Europe)
To exit the PROGRAM STORE menu, press the MEAS/ESCAPE key and you will always go directly to the main menu
MEASURE. Press MEAS/SPECT again to go to SPECTRUM mode. Easy, don't you think? Remember that it is not
possible to store on identical programmes, because this is not necessary, however if you want to do this, simply move the
frequency by 25 KHz in TV and 100 KHz in SAT.
N.B. If in the MEAS menu, instead of the programme you find two small lines, you must have varied a parameter, enter in
the programme and bring it to the one required (or if you want to keep that configuration press MEMORY to store it).
The VHF channels, e.g. E10-Z10-S10 cannot be selected from the numerical keyboard, but must be selected using the UP
and DOWN keys.
REMEMBER THAT:
• You have 99 memory plans available
• You can store up to 199 mixed programs in each plan (RADIO-AN TV-QPSK-QAM- 8VSB - COFDM-DAB)
• We suggest you store a plan for each city or each type of installation; this will facilitate the registration of measurements
and data of the various installations (Data Logger) and the subsequent PC filing and print-out.
For your commodity you can note the plan and program in the table on pages 108 and 109.

Description
key for 2 seconds, select SYNC AREA using the encoder.
The picture is moved and the synchro graphic generated, locked to the signal received, to show the function “visualisation of the active synch area”.
As you can see the darker bar (black) is the synchronism, the dark grey bars are the front and back on the synchro and the lighter bar represents the chroma BURST.
a) THE MAIN OBJECTIVE OF THE MEASUREMENT is to analyse the SYNCHRO H area in time, to visualise possible interferences or reflections, as well as signal distortions and
compressions.
b) In the synchro’s lighter bars, it is much easier to recognise all the various types and quantities of reflections and/or interferences, even with moving pictures, because this active area is not
influences by the contect of the picture and it should be clean in ordeer to have a perfect picture. For example, a white line to the write of the synchro represents a “reflected signal”, which is
whiter, stronger and viceversa.
c) When there are signal compressions and/or saturations, the dark/light areas tend to unify in intensity (compression) and distort (saturation). This function shows all the phenomena described
above, which are usually difficult to see with moving pictures or with a simple SYNC visualisation.

SPECIAL TV BARS SCAN FUNCTION
The BARS SCAN function activates the graphics representation of the bar spectrum. Each bar shown represents the value of the level/average power of TV programes
(analogue or digital) stored in the chosen memory plan.
This spectrum representation is useful in the TV band to easily equalise a channelised head-end output. The analog terrestrial channels are represented by a thin bar whose
height is proportional to the level of the video carrier, whereas the digital terrestrial channels are represented by a wider bar whose height is proportional to the average power of
the digital package.
How to activate the TV BARS SCAN function:
DIRECT: Select a memory plan, previously stored, then press the key
for 2 seconds. Move from one bar to another using PROG. NAME.

NOTES:
1. PROPAGATION SPEED MEASUREMENT:
If the propagation speed percentage is not known (because it is not specified by the manufacturer), you can
calculate it using the reflectometer function.
With reference to the connection diagram on page 40, connect the “T” adapter at the output to 5 meters of
coaxial cable whose propagation speed is unknown, without closure resistance. Then recall the menu and
vary the propagation speed percentage until 5.0 m appears in the “DISTANCE” window. The resulting
propagation speed value obtained is the one related to the cable you are using.
2. PROGRAMMING MODIFICATION:
To vary the programming of any cable, simply change it manually and the new parameter will store
automatically.

FAST & ADVANCED AUTOSCAN FUNCTION (AUTOMATIC TV SEARCH)
The Autoscan function is required to carry out the automatic scan of a channel plan, to search for Analog, Digital COFDM and QAM (if the optional board is fitted) TV
channels and to automatically store them in a memory plan.
You can chose two types of autoscan modes: Fast and Advanced.
•
•
FAST: when this is set, the meter carries out a search by storing in the selected memory plan, the analog and digital TV channels whose Level/Power is above the
selected threshold. Considering that all digital muxes are COFDM, no QAM/COFDM discrimination is made.
ADVANCED: when this is set, the meter, after completing the search for analog and digital TV channels, identifies the COFDM from the QAM muxes and selects and
memorises the main parameters necessary to lock onto the digital packages. Once this procedure is completed, the channels are stored in the plan that was previously
selected.
SELECTION OF THE TYPE OF AUTOSCAN:
To select FAST or ADVANCED autoscan, enter in CONFIG. by keeping the

A5 - TROUBLE SHOOTING
For all faults always call the manufacture or the authorized service centre in your country. Never return an analyzer directly to
the manufacturer before consulting them first and obtaining their specific instructions. Please find below the most common
problems that could occur and which can be easily solved:
PROBLEMS & SOLUTIONS:
P:
S:
The analyzer does not work or is working incorrectly even if it is connected to the mains:
Verify that the ”MAINS” [24] green LED is on. If it is not on control the ac/ac adapter supplied with your analyzer.
P:
S:
The batteries can not be charged:
Verify that when the meter is off the "MAINS” [24] and “BAT CHRG” [15a/b] LED’s are on. Verify the internal battery
status.
P:
S:
There is poor picture quality or the picture does not appear:
Check that the “BRIGHT” [33] and “CONTRAST” [32] trimmers, found on the left side of the instrument, are adjusted
correctly (see page 73).
P:
S:
The analyzer does not respond to the commands:
In the rare cases that the analyzer no longer responds to the front panel commands, keep the ON/RESET [24] button
pressed for 10 seconds. No information is lost during this operation (e.g. memory plans, data logger, etc.)
P:
S:
During battery charging the BAT FULL [15a] LED turns on immediately:
There could be a problem with the batteries, contact the service for further information.
P:
S:
With weak TV signals or signals with lots of interferences, the TV pictures can not be tuned:
Exclude the OSD and reactivate it; it should lock
P:
S:
The graphics (words) do not tune during the frequency tuning of analog and SAT & TV programmes:
Disconnect the RF input signal for a few seconds and the words should become stable.
NOTES:
•
To report any faults, photocopy and fill-in the attached “FAULT IDENTIFICATION FORM” and send it to the
manufacturer.
•
As the meter is very complex, we strongly advise that repairs should only be carried out by expert staff, authorized by
the manufacturer.
•
The analyzer is built almost completely using SMD components and it is therefore not easy to repair; for this reason the
manufacturer. does not provide any circuit diagrams.
•
If the manufacturer considers that the analyzer has to be returned for repair, photocopy and fill-in the “EQUIPMENT
REPAIR and/or Service Form” and attach it to the meter when returning it.
97
DM-14B & DM-14C User’s Guide
A6 - LEAD BATTERY MAINTENANCE AND RECHARGE
•
•
The analyzer has a + 12 V, 7 A built–in power supply with lead batteries.
Low battery indications:
–
+ 1 beep: will appear 30 minutes before switch off.
–
+ 2 beeps: will appear 20 minutes before switch off
–
+ 3 beeps: will appear 5 minutes before switch off.
All the messages are repeated every 30 seconds and are accompanied by an audible tone, even if the volume is low.
Recharging procedure of the lead batteries provided with the analyzer:
a) Connect the adapter to the mains and insert the plug into the connector socket [27] (or in a vehicle using the optional
cigarette lighter adapter).
b) Turn off the DM14B/C and the BATTERY CHRG [15a] LED will light up (if the instrument is turned on, the batteries
will not recharge).
c) Keep the batteries under charge until the FULL BATTERY LED lights up [15b] together with the BATTERY CHRG
[15a] (batteries which are completely discharged require approximately 4 hours).
d) 50% of the charge can be achieved in about an hour.
Battery replacement procedure:
a) Open the upper cover of the instrument (not indispensable).
b) Unscrew the eight external screws in the back battery box.
c) Pull out the battery box, remove the two Faston clips, remove the four screws in the battery holder metal cage.
Replace the normal batteries with 12 V, 7 A Lead batteries, guaranteed for at least 200/500 loads.
NOTES:
• The "BATTERY CHRG" LED on the front of the DM14B/C lights up when the meter is recharging.
•
The fully charged battery capacity is 4 hours at 25°C, and decreases considerably if the working temperature is higher
than 35°C or less than 10°C.
•
The batteries do not recharge if the DM14B/C is on.
•
Once the recharging procedure has been completed the BATTERY CHRG LED turns off and the FULL BATTERY
LED turns on.
•
Once the battery is charged the battery charge automatically stabilizes and the meter can be connected to the mains for
as long as you like.
•
As you know, lead batteries usually have overload problems. The batteries can be damaged indefinitely if they are left
discharged for more than 24 hours.
•
In the DM-14 the battery discharge is controlled by a microprocessor, which turns off the instrument in order to
maintain the battery residual charge. This residual charge means that the batteries do not degrade without recharge for
a maximum of 3 months.
BATTERIES NOT UNDER GUARANTEE:
The batteries are a standard format: 12V 7 A Lead. They can be easily purchased from all distributors of electronic
components and electrical supplies, at a cost of approximately 5 Euros / $.
N.B. RO.VE.R. does not supply replacement batteries because the transport costs exceed the cost of the batteries.
