Firmware updates are used to either enhance the functionality of your tool or resolve software crashes in the system. Unfortunately, due to the latest security functionality of android some phones and tablets will allow you to see N2 but provide an "initialization code 2" which tells us the system can see the N2, but communication is blocked by Android. We resolve this by doing a firmware update. Watch an in-depth video here: https://vimeo.com/668741730 or a quick video here on how to do this: https://vimeo.com/668747391

Connection issues with the N2 can occur for several reasons. The following is a list of reasons and how to resolve them: 1. Bluetooth Antenna not activated on phone or tablet | Resolution: Turn on 2. Application not given Bluetooth permissions| Resolution: activate in settings or reinstall app and provide app with location settings permissions. 3. Initialization code “-2” (Android operating system is blocking communication) | Resolution: Do a firmware update (See Firmware update FAQ for instructions on how) 4. Initialization code 1 | Resolution Do firmware update 5. The tool connected once, then cannot connect later | Resolution: Close app, try again, if issue persists, reboot phone/tablet try again, If issue persists, call tech support or do firmware update.

Unscrew the back panel of the N2, split the housing in 2. Remove the board from the top half of the housing by pressing your fingers between the housing and the board at the pins area. Only touch the outer edges of the board when possible. Replace/install batteries and fuse

Once you have installed batteries in the N2 and have installed the mobile application from your app store of choice (or the Curie website) there is no need to go into the Bluetooth settings of your phone, tablet or computer. As long as you installed the app, gave the app all permissions it asked for when you installed it AND your Bluetooth is active, the app will automatically see the N2 in the "Sync" screen in the app. If you still do not see the N2 in your sync menu, try tapping the "Sync" button at the bottom of the Sync screen.

The N2 is the most sensitive measurement tool in your arsenal. The sensitivity allows the N2 to see and measure voltage, resistance and amperage that other tools cannot. What you are seeing is ghost voltage. The N2 will have a floating ghost voltage when it is not connected to a circuit. The ghost voltage may float anywhere from -500 micro units (volts, ohms, amps) to 1-2 mili units (volts, ohms, amps) depending on how much electrical magnetic field disturbance is around your work area. Once the N2 is on a circuit it will give you extremely accurate measurements and readings. Ghost voltage is a good thing and a sign of a very accurate tool. Please note that when you see micro volts, ohms or amps that 1 micro unit = .000001 base unit, so if you see 120 micro volt that is .000120 volts... that is still "zeroed". If you do not want to see these tiny measurements, please change your auto ranging to manual ranging.

8000 samples per second. This allows for most components on the vehicle up to fuel injectors.

\You can insert a 32 GB sd card formatted in FAT32 (not included) into the N2 and it will allow the tool to begin logging. Once you insert the sd card, you must activate logging in the meter mode menu by tapping on the logging option (bottom left) and choosing to both activate the logging AND the frequency in which you want data logged. Max = no delay full data dump, the other options are time delays in which a single reading will be saved to the file.

At this time we do not have a log viewer window built in. This is on the list of features to add, however there are more important updates coming soon.

The N2 uses Bluetooth 4.0 low energy protocol. This allows the N2 to be seen by the app and make a much more seamless user experience for you.

The Bluetooth speed of the N2 does not affect the measurements. All measurements are done onboard and transmitted to the app in packets. the data will not be lost. There may be an unnoticeable delay in the initial transmission of data, but for all intents and purposes the readings are live. Please note that measurement speeds are modifiable and if the tool is measuring at a low rate (Please see "How fast can N2 measure?") the readings will appear slow and clunky. Simply speed up measurement speeds to see "live readings" in Realtime without delay.

Yes. The N2 is a full TRMS meter that has the ability to shut off TRMS and give a true waveform measurement. You can view square waves and all waveforms in the graphing screen. *Note you must activate "Waveform" function to view square waves and shut off TRMS measurements. Also the N2 could be considered a DSO but because we do not designate the N2 an oscilloscope we do not classify this.

32 GB Max, SD or SDHC format only. NO SDXHC.
