• No. 2 transducer connection cables L 2.5 m
• No. 1 heavy duty spiral cable L 2 m
• No. 2 magnetic bases Ø 25 mm
• No. 2 probes
• No. 1 250.000 Cpm Hi-speed, laser photocell complete with upright and magnetic base
• No. 1 roll of reecting paper
• No. 1 USB stick for data transfer
• Angle rule
• Battery charger
• Universal plug
• Case complete with carry strap
• User manual
1.2 optIonal accessorIes
• Bluetooth thermal printer for direct printing of certicates on normal or adhesive thermal paper
• Protective cover
• Acceleration transducer type DM-40 complete with connection cable and magnetic base
• Proximity sensor type ARA-18 complete with stand, cable and magnetic base
• Connection cable for transducers L 5 m
• Extension cable, length 10 metres, for transducers
• Extension cable, length 10 metres, for photocell
• CEMB ADS software for data storage and management
aFter connecting the printer via bluetooth, wait For about 5 seconds to allow completion oF the automatic re-
cognition and initialization procedure. only at this point will it be possible to make aprint-out by pressing relative

1.3 connectIons
1 Battery charger
2 Internal heat dissipation area (electronics)
3 Network port (useful to connect the instrument to a PC and share a folder for data exchange between the two)
4 2 USB ports type A (master)
5 Instrument reset button
6 Battery charge indication led
7 Photocell input
8 2 inputs, measuring channels
To connect the sensors and photocell, merely plug the connector in the corresponding socket, pushing it until it clicks into
place; make sure that the safety connection is correctly aligned as shown in the gure.
Instead, to extract the connector, press its end part (blue or yellow) and at the same time pull the main body (grey), in order
to release it.

1.4 battery
The N600 instrument is provided with a built-in rechargeable lithium battery, which allows autonomy of more than eight hours
under normal operating conditions of the instrument.
The battery status is indicated by an icon in the upper right hand corner of the screen.
battery fully charged
battery partly charged
battery almost at (battery life remaining when this appears is approx. one hour)
battery at: recharge within 5 minutes
In these conditions, any still active measurements are interrupted and therefore not yet saved.
————————————————————————————————————————————————————

could become damaGed IF allowed to be Fully dIscHarGed. For tHIs reason It Is adVIsable to recHarGe tHe battery at least

————————————————————————————————————————————————————
asthe greater consumption is due to the back lighting oF the lcd display, the latter is switched oFF automatically
aFter two minutes iF no button is pressed. the pressing oF any button (except For and those oF the alphanu-
meric keypad) is suFFicient to switch the back lighting on again.
1.5 General adVIce
Keep and use the instrument far from sources of heat and strong electromagnetic elds (inverters and high-power electric
motors). Measurement accuracy could be impaired by the connection cable between the transducer and instrument, there-
fore it is recommended to:
• not allow such cable to have sections in common with power cables;
• prefer a perpendicular arrangement when overlapping power cables;
• always use the shortest possible length of cable; in fact oating lines would act as active or passive antennae.

2. General layout
2.1 keys/buttons on tHe control panel
The control panel of the CEMB N600 instrument incorporates a keypad where the various keys or buttons can be subdivided
by function:
►ON / OFF button
Press this button to switch the instrument on; hold it down for at least 3 seconds to switch it off , then release the
button.
aFter pressing , the instrument is ready For use only at the end oF the switching on procedure, signalled by
the appearance oF the home screen (
home screen - menu
).
aFter the insrument has been switched oFF, about 30 seconds must pass beFore it can be switched back on again.
►Buttons for navigating between the pages
When this button is pressed in the setup screen, it conrms the settings selected and allows going onto the next
screen. Instead, in the Measurement screen, it has the function of starting/stopping the actual measurement (
START / STOP THE ACQUISITION).
toFacilitate use oF the instrument also with the leFt hand, the button is located on both sides oF the
display.
When this button is pressed, it causes quitting of the current screen with return to the previous one, without taking
into account any changes (or saves) in the settings
Used for returning to the Main page, from any other page.
►Function keys
Each function key is linked to different functions in the various screens. Such functions are indicated in each individual case
by the buttons shown at the bottom of the display: each function is activated by pressing the function key under it.
