Press and release the HOME [A] key.
5 TURN THE METER OFF
Press and hold for 2’’ the HOME [A] key.
6 CHECK THE BATTERY CHARGE STATUS
When the meter is on, at the bottom left corner of the LCD display [C] an icon will show the
current power source of the meter: built-in battery or mains external feed.
Build-in battery feed Mains external feed
Connect the supplied AC adaptor or the supplied cigarette lighter adaptor to the [S7] inlet
(located on the left side of the meter) to recharge the built-in battery. When the meter is
connected to an external power supply, the LED indicator [F] (located on the meter front
panel) turns on. When the external power connection is suitable to re-charge the build-in
battery, the LED indicator “CHARGE” [G] (located on the meter front panel) also turns on.
When the meter is off, but it is still connected to an external power supply, the built-in battery
fast charge mode is activated, and the LED indicators [F] and “CHARGE”[G] turn on brighter.
Don’t leave the instrument in LOW BATTERY conditions (1/4 charge or less) for more
than 2 months to preserve the capabilities of the built-in battery. Should the
instruments be stored for longer periods, it is required to periodically charge its
battery.

7 THE ENCODER – STANDARD NAVIGATION MODE
Navigate into the various functions and menus of the DIGIMETER M3 is quick and easy. A
multi-function continuous encoder [D] allows the user to surf all the meter
functions, easily selecting the required function and quickly setting the desired values, by
simply rotating and pressing the encoder itself. Thanks to the ergonomic design of the
encoder knob just one hand is required.
When an item in the LCD [C] is black-highlighted, rotating the encoder [D] one step
clockwise will highlight the next item; rotating the encoder [D] one step counter-clockwise will
highlight the previous item.
Once black-highlighted the desired item, press and release the encoder knob, and the black
highlight will start blinking. When the black highlight is blinking, rotating the encoder [D] one
step clockwise will raise the value of the selected (highlighted) item; rotating the encoder [D]
one step counter-clockwise will decrease the value of the selected (highlighted) item. Once
set the appropriate value, just press and release the encoder knob, and the black highlight
will stop blinking, allowing you to move to a different item by simply rotating the encoder
knob.
These features will from now on be referred to as “Standard Navigation Mode”

Using the Standard Navigation Mode, you can set up the signal level end-of-scale.
8.5 ADVANCED SETTINGS
The patented Autodiscovery feature is capable to automatically detect the standard of the
tuned signal (analogue TV, DVB-T, DVB-S, QAM, …), the relevant bandwidth as well as the
appropriate Symbol Rate (where applicable). This feature allows the user to navigate any
17

USER MANUAL
frequency band by simply surfing the selected frequency band or by simply adjusting the
frequency value to be tuned; from time to time and with no action by the user required the
meter will detect the proper standard for the received signal, and will set the meter
accordingly to it, together with the appropriate measurements set.
Under rare and very critical conditions (like a co-channel interference caused on a DVB-T
signal by an analogue TV signal receivable on the same channel and with a comparable
signal strength), the Autodiscovery system could set the meter to manage the analogue
signal (the interfering one) instead of the digital one.
In these conditions it is possibile to manually select the signal standard and the relevant
measurements set.
MANUAL SIGNAL STANDARD SELECTION
Select a User Defined (MANU) Memory Plan, as described at Chapter 10.2 “NAVIGATE
INTO THE CHANNEL PLAN (USER DEFINED CHANNEL PLAN)” at page 20. Using the
Standard Navigation Mode tune the desired channel or the desired frequency value.
From the channel power (or signal level) measurement screen, using the Standard
Navigation Mode, highlight the signal standard (TV ANALOG / TV COFDM DVB-T/H /
…) and select the requested one. Then press the encoder [D] knob to enter your
selection.

the required channels group (MANUxx plan).
Press once and release the MEAS [5] key.
The LCD [C] top row will display (from left to right): the selected channel plan, the currently
tuned channel and the corresponding frequency value.
Press the encoder [D] to highlight the current channel ID and rotate it to surf the channels
within the selected memory plan. Each step of the encoder moves the channel ID one step
forward or backward. To speed up the channel ID selection, rotate the encoder [D]
continuously.
THE METER WILL TUNE ONLY THE CHANNELS INCLUDED IN THE SELECTED
CHANNEL PLAN. To explore/navigate into a new user defined channel plan, press
once and release the PLAN key and, using the Standard Navigation Mode, highlight
the MANUAL MEMORY item to select the required channel plan.
FINE-TUNING THE FREQUENCY VALUE
Should you need to change the frequency value, using the Standard Navigation Mode
highlight the current frequency value and set the desired frequency value (Frequency
range: 45 – 878 MHz).
DIRECT FREQUENCY INPUT
Using the Standard Navigation Mode, highlight the current frequency value, and then
press and hold the encoder knob [D] for 3’’. The frequency value will be reset and a
black icon will appear to right of the “F” indicator.
This way, the BLOC NUM function is active. Enter the desired Frequency Value (in
MHz) using the numerical keys on the front panel (as described into the chart FRONT
PANEL AND KEYBOARD at page 8). To insert the comma (e.g. frequency value:
21
839,25 MHz), press the SAT FINDER [3] key. Once entered the desired frequency
value, press the encoder knob[D] to confirm the selection.
in case the frequency value is not applicable or invalid in the TV service range (e.g.
48354 MHz), the “OUT OF RANGE” warning will be displayed and the entered value
will be voided.
WHO IS THERE?AUTODISCOVERY ®
Once selected or fine-tuned the desired frequency value, the meter can provide the
user with the Autodiscovery ® function to self-detect and tune the received signal, both
analogue and digital, and to set the appropriate signal bandwidth.
Suppose you are starting from the frequency value 699,95 MHz, which has no
correspondence with any significant frequency value in any country channel plan:
DIGIMETER M3
USER MANUAL
Press once and release the HELP [7] key. The meter will start the
Autodiscovery ® process and will display a rotating bar as an “in progress” indicator.
When terminated, the meter displays the Autodiscovery ® results. In this case the
received signal was detected as analogue TV type at 695,35 MHz (as) video carrier
frequency.
In this case the meter was receiving an on-air analogue TV signal on EU channel 49,
thus corresponding to a 695,25 video carrier frequency. From the practical point of
view, as well as from the end user one, the meter has correctly detected the received
signal even if the start frequency (699,95) was 4,6 MHz far from the correct one.

FM /FM RADIO SIGNALS TUNING [87,5 – 108 MHz]
When in the main Audio peak level measurement screen, using the Standard navigation
Mode, highlight the tuned signal type (TV ANALOG / TV COFDM DVB-T/H).
Using the encoder [D], select the item FM RADIO.
DIGIMETER M3
USER MANUAL
On the right handside of the F icon the tuned frequency is displayed, and the received
audio signal can be listened through the meter built-in loudspeaker.
Change the frequency value using the Standard Navigation Mode, or proceed as
described at page 21 DIRECT FREQUENCY INPUT

10.3 EXPLORE USER DEFINED CHANNEL
To create a channel plan (user defined list of channels), proceed as described in Chapter
15 CREATE MEMORY PLANS at page 46.
Using the Standard navigation Mode, highlight the AUTOtv MEMORY item, and press the
encoder knob [D] once. The black icon of the AUTO memory plans will start blinking. Rotate
the encoder [D] to select the required channel groups.
Press once and release the MEAS
[5] key.
Proceed as described in Chapter 10.2 NAVIGATE INTO THE CHANNEL PLAN (USER
DEFINED CHANNEL PLAN) at page 20.
