2.0 INTRODUCTION
2.1 Battery Care
The OMNIA-6 instrument uses a Ni MH rechargeable battery and includes smart charging techniques to
maximize battery life. For recharging the internal battery, Ro.Ve.R. Laboratories S.p.A. includes a single-unit
battery charger as a standard accessory.
Charge the battery for a minimum of four hours before initial use. The fastest battery recharge time is
obtained with the OMNIA-6 turned off.
When the battery charge is low, an audible warning is heard and a low battery message appears on the
display.
2.2 Power On
Turn on the meter by momentarily pressing the power/reset key.
2.3 Power Off
Turn off the meter by pressing and holding the power/reset key for three seconds. Pressing and
holding
for ten seconds resets the meter and restores normal operation.
2.4 General Instructions for Navigating On-Screen Selections
The basis for screen navigation is the position of the selector tool (*). The action necessary to move the
indicator depends on whether Text or Graphic screens are displayed.
On menu screens, using and keys move the selector tool (*) from one item to the next.
Figure 1: Text Screen Navigation Example.
Omnia-6 User’s Guide Draft Version

For graphic screens, the , and keys move the selector tool (*) clockwise and anti-clockwise,
respectively, to items with more than one user selection. Note that the selector tool rotation is relative to its
original starting position and may sometimes appear to move in the wrong direction.
Figure 2: Graphic Screen Navigation.
With the selector tool (*) beside it, the user can press
and update the values on the selected item. A
solid arrow will appear beside the current value. Pressing the arrow keys (
, ) will then allow the
user to change the value. Pressing
again will keep the current value and deactivate the ability to
update the item. The solid arrow indicator is replaced by the selector tool (*).

darker contrast.
4.2 Units
Units of measurement offer dBµV or dBmV options.
4.3 Shutdown
This sets the automatic shut down time. Two options are available: Off (the instrument only turns off
manually) or 5 minutes (the instrument turns off automatically when no key is pressed for the stated time)
4.4 Light
This function allows you to select the time duration of the back-light display start-up. Select either the backlight remaining always on, or it turning off after 15, 30, 45 or 60 seconds without use.
4.5 Specmode
This function allows you to select either automatic or manual spectrum mode.
4.6 Buzzer
This function allows you to activate an acoustic signal which helps you carry out the installation.

4.8 Clock?
In this Menu you can define the clock’s values and the date.
Pressing
on this item will take the user to the following menu. Enter the appropriate date and time.
Selecting PREV and pressing
allows you to return to the Device Configuration Menu.

4.9 File Manager
This area is used to delete storage files created by the user. Files that can be deleted are:
Custom Plans – The first plan in the system may not be deleted, but can be edited using internal functions.
4.10 Self Test
This function allows you to carry out a “health check” on the parts which make up the Omnia-6. Press any
key to quit the diagnostic test display. This also allows the visualization of the instrument’s Hardware and
Firmware versions.

4.11 Proof of Performance
This function allows you to activate the instrument, at a specific time, to carry out measurements in CATV
installations.
START: Set the start time
Intervall: Set the measurement interval (from 15 minutes to 8 hours)
Analog: All the measurements are activated
Digital: It is possible to activate or deactivate the MER or bBER measurements
Navigate using the and keys on GO and press to confirm.
Confirm the OK selection using the key.
WARNING: when you confirm, all the other previously saved Loggers will be cancelled so that the numbering
of the new loggers starts from 1.
N.B.
- Before setting the instrument’s turn on START time you must set the instrument’s clock (see paragraph
3.0 and 4.8)
- If you confirm the selection, all the previously saved loggers will be cancelled.
- During this function the instrument must be connected to the mains power supply.
- To interrupt the measurement during scanning, simply press another key. To deactivate the
measurement when the instrument is already in Standby, simply turn in on using the ON key.
