¶ Starting Measurements
Measurements should start automatically as a default feature of the device. You can manually stop the measurement of the device from within the eNView onboard web portal, you must remember to restart the measurement if you do decide to use this feature. There is no automatic way for the measurement to start if the last state was stopped.
¶ Calibration
Noise and vibration can be calibrated to ensure that the unit is measuring the levels correctly.
¶ Noise
Noise is calibrated by utilising a microphone calibrator with 94dB level. Within the web portal, go to:
Settings -> Calibrate Noise
Press run, the calibration process lasts for 30 seconds. When finished a dialog box will appear to let the user know the calibration value.
Check with the live data that the measured value is 94dB.
¶ Vibration
Vibration calibration is carried out using manufacturer provided sensitivity levels.
Go to:
Settings -> Calibrate Vibration
Fill out the sensitivity form and press save.
You can check that the levels are expected in the live view.
¶ Configuring Measurement
Measurement configuration is carried out within the web portal, you can select the spectral analysis type (third octave or single octave) and set the integration period.
¶ Inserting SIM Card
ENView features a 4G LTE modem, this requires a SIM card for cellular connectivity. The socket for inserting the SIM card is within the enclosure of the device. Remove the 2 raised star drive screws on the side of the unit to reveal the main internals. At the top left cut-out, there is a slot for a SIM card and SD card. Ensure that the device is powered off prior to inserting SIM card.
The accepted SIM card size is nano. This is commonly found in most cell phones.
¶ Technical Information
¶ Data Storage
The eNView features 2 types of non-volatile storage, these are the internal device storage and SD card-based storage.
All settings and parameters are stored within the internal device storage, these cannot be accessed by a user and can only be accessed by the manufacturer. If corruption of these files occurs the device will shut down and will require servicing by the manufacturer.
Telemetry is stored on SD card storage; this is to increase the longevity of the internal device storage. The eNView can only support a maximum SD capacity of 32GB, this is because of the internal electronics. SDHC cards are supported.
The manufacturer recommends SanDisk industrial 32GB SDHC card.
When installing a new SD card, this must be formatted to MSDOS FAT32. The internal file structure of the SD card is defined and allocated by the device, if the SD card is removed from the device and contents modified in a PC this could result in the device entering an error state. All telemetry files stored on the SD are signed and feature the extension “.kpdat”.
The files can be removed from the SD card and viewed within the eNView desktop app.
The SD card will not run out of storage as there is a rollover system in place which will remove all files which are 60 days or older.

¶ Safety and Handling
¶ Handling
Handle eNView with care. It is made from plastic and has sensitive electronics inside. The eNView or its battery can be damaged if dropped, burned, punctured, or crushed, or if it comes in contact with liquid. If you suspect damage to eNView or the battery, discontinue use of eNView, as it may cause overheating or injury.
When equipped with vibration and noise measurement transducers, care should be taken when handling. Vibration measurement transducers contain crystals which can be broken if dropped from a height. The Microphone transducer is constructed from delicate materials, dropping from a height can affect the accuracy and will result in the transducer needing to be returned to the manufacturer for calibration.
¶ Repairing
eNView should only be serviced by a trained technician. Disassembling eNView may damage it, result in loss of splash and water resistance, or cause injury to you. If eNView is damaged or malfunctions, you should contact KP Monitoring services for service. Repairs performed by untrained individuals or using non-genuine parts may affect the safety and functionality of the device. Contact support@kpenview.com for further questions.
¶ Battery
Safety for the 88Wh Internal Li-on battery pack
Avoid charging your device around flammable materials, such as a bed, couch or on paper. Charge your device with the power cord that came with it. Never keep li-ion batteries near heat sources or in high temperatures, such as direct sunlight, radiators or laptops.
Lithium-ion batteries (Li-ion) should not be stored for longer periods of time, either uncharged or fully charged. The best storage method, as determined by extensive experimentation, is to store them at a low temperature, not below 0°C, at 40% to 50% capacity. Storage at 5°C to 15°C is optimal. Since lithium batteries self-discharge, it is recommended that they must be recharged every 12 months.
We can further divide it into short-term storage and long-term storage.
Short-term storage: Store the battery in a dry place with no corrosive gases and a wet temperature between -20°C -35°C, higher or lower temperature will cause the metal parts of the battery to rust or the battery to leak.
Long-term storage: As long-term storage will cause the battery activity passivation and accelerate the self-discharge rate, the ambient temperature should preferably be between 10℃-30℃, in addition, it is necessary to do a charge/discharge cycle every 3 months to maintain its activity and recovery performance.
Charge 40% to 50% of the battery charge and refrigerate in a dry environment. Cooler temperatures and less charge is conducive to maintaining the life of the battery, but too little charge cannot be, because the battery will be self-discharge in storage, once the battery slowly run out of power, it will seriously shorten the battery life.
Do not charge the battery under fire or extreme heat. Do not use or store the battery near a heat source (such as a fire or heater). If the battery leaks or emits a peculiar smell, immediately move it away from the open flame; When the battery swells up, leaks, etc., stop using it immediately.
Do not put the battery in water or get it wet.
Do not throw the battery into the fire or heat the battery.
Do not connect the battery directly to a wall socket or car cigarette lighter socket.
Do not short-circuit the positive and negative poles of the battery with wires or other metal objects. It is forbidden to transport or store the battery with necklaces, hairpins or other metal objects.
Do not knock, puncture, step on, modify, or expose the battery to the sun, and do not place the battery in a microwave or high-voltage environment.
Do not hit, throw or subject the battery to mechanical shock.
Do not disassemble the battery in any way.
Do not mix the battery with metal objects, in case the metal objects touch the positive and negative electrodes of the battery, causing a short circuit, damaging the battery, or could even cause danger.
Do not use the battery if it emits peculiar smell, heat, deformation, discoloration, or any other abnormal phenomenon. If the battery is in use or charging, it should be removed from the electrical appliance or the charger immediately and stop using it.
In the transportation process, pay attention to moisture-proof, moisture-proof, avoid squeezing, collision, etc., to avoid battery damage.
Do not use or place the battery under high temperature (in the hot sun or in a very hot car), otherwise it may cause the battery to overheat, catch fire or function failure, and shorten its life.
Do not store in places with strong static electricity and strong magnetic fields, otherwise it is easy to damage the battery safety protection device and bring insecurity.
If the battery emits peculiar smell, heat, discoloration, deformation, or any abnormality during use, storage, or charging, immediately remove the battery from the device or charger and stop using it.
- Discarded batteries should be covered with insulating paper to prevent fire and explosion.
- For Lithium-ion batteries which need to be stored for a long time and not used, they should be kept in a state of 50%-60% charge. They should be recharged every 3 months and recharged every half a year.
- Attention should be paid to moisture-proof and moisture-proof, to prevent squeezing, collision, etc., to avoid battery damage.
- It is forbidden to use or place the battery at high temperatures (in hot sunlight or in very hot cars), otherwise it may cause the battery to overheat, catch fire or fail in function, and shorten its life.
- It is forbidden to store in places with strong static electricity and strong magnetic fields, otherwise it will easily destroy the battery safety protection device and bring unsafe hidden dangers.
- If the battery emits an odor, fever, discoloration, deformation, or any abnormality during use, storage, or charging, immediately remove the battery from the device or charger and disable it.
Daily fire extinguish equipment and materials needed: dry powder fire extinguishers, sprinklers (water), fire blankets (for warehouses).
