COMET U0110 Data Logger

Product Information

The Dataloggers Uxxxx family is a range of devices used for measuring and recording various values such as temperature, relative humidity, dew point temperature, barometric pressure, and CO2 concentration. The devices come in six different types: U0110, U3120, U3430, U4130, U4440, and U8410. The measured values are recorded and downloaded using the computer with the COMET Vision software installed, which can be found at www.cometsystem.com. The devices are equipped with internal sensors for measuring the various values and have a USB interface for communicating with the computer. The device can be fastened to a wall with screws or inserted into a wall holder (LP100), which is an optional accessory. The device can also be operated as a portable device.

Product Usage Instructions

1. Installation: To install the device, fasten itto a wall with two screws or insert it into the wall holder LP100 (optional accessory). Ensure that the device is mounted appropriately as inappropriate selection of the working position and the measurement location may adversely affect the accuracy and long-term stability of the measured values. The device should also be located as far as possible from potential interference sources.
2. Operation: To operate the device from the keypad, press and hold the lower key. After the light up the row with menu items, release the key and briefly press the upper key. Press the upper key to scroll through the menu items (deviceturning On/Off, deleting the Min/Max values in the device, etc.). Press the lower key to confirm (SET).
3. Maintenance: The devices do not require special maintenance. However, it is recommended to verify the measurement accuracy regularly by calibration.
4. Safety Instructions: The installation, electrical connection, and commissioning should only be performed by qualified personnel in accordance with applicable regulations and standards. Devices U3430, U4440, and U8410 are equipped with an internal Li-Ion battery. Observe the recommended operating and storage conditions. Should the battery casing get damaged or should the whole device get destroyed, carry it outside the fire, high temperature, or water affected area to a safe fire-protected place. Protect yourself and the environment against escaping gases and against being soiled with the battery electrolyte.

PRODUCT DESCRIPTION **

**

The dataloggers Uxxxx with internal sensors are designed for measuring and recording physical and electric quantities with an adjustable logging interval from 1 second to 24 hours. The measured values, or the average values and min/max values over a recording interval are stored into the internal non- volatile memory. The data logging mode can be cyclic (when the data memory is completely full, the oldest data are overwrite by the new ones), or non-cyclic (the recording will stop once the memory is full). The device also allows to the evaluation of alarm states – exceeding the limit of the measured value or falling below this limit, exceeding the limit of memory filling, technical defects of the instrument or probes. The alarm signalling can be realised visually, optionally by a symbol appearing on the display or by a short blink of an LED, or acoustically. The data recording can be performed continuously or only when an alarm occurs. The devices are powered by internal a replaceable lithium battery (U0110, U3120, U4130) or by internal Li-lon battery (U4130, U4440, U8410). Device setting, recorded data downloading and online monitoring is carried out using the computer with the COMET Vision software installed (seewww.cometsystem.com). The USB interface is used to communicate with the computer.

INSTALLATION AND OPERATION

Fasten the device on the wall with two screws or insert it into the wall holder LP100 (optional accessory). Datalogger may be operated as a portable one. In this kind of operation avoid the device falling down. Try to maintain the proper working position.

•  Please pay attention to the device mounting. Inappropriate selection of the working position and the measurement location may adversely affect the accuracy and long-term stability of the measured values.
• The device should be located as far as possible from potential interference sources

Set-up the device

• Device setup can be performed using the computer with the Windows 7 operational system or higher. Minimum HW requirements are 1.4 GHz processor and 1 GB memory.
•  Install the COMET Vision software into computer (the program is available free of charge at www.cometsystem.com
• Connect the datalogger to the computer. Use an USB cable with USB-C connector (max. cable length 3 m). If the device is connected properly, its current status is displayed in the Device Home panel.
•  Click on the Configuration button. The device configuration will be downloaded and you can change the settings of some items
• Save the new configuration into the device
• Disconnect the device from the computer and close the USB connector with a closing cap

Operating the device from the keypad

• Press and hold the lower key. After the light up the row with menu items, release the key and briefly press the upper key.
• Press the upper key to scroll through the menu items (device turning On/Off, deleting the Min/Max values in the device, …)
• Press the lower key to confirm (SET)

The devices do not require special maintenance. We recommend verifying the measurement accuracy regularly by calibration.

SAFETY INSTRUCTIONS

• Installation, electrical connection and commissioning should only be performed by qualified personnel in accordance with applicable regulations and standards
•  Devices U3430, U4440 and U8410 are equipped with an internal Li-lon battery. Observe the recommended operating and storage condition. Should the battery casing get damaged or should the whole device get destroyed, carry it outside the fire, high temperature or water affected area to a safe fire-protected place. Protect yourself and the environment against escaping gases and against being soiled with the battery electrolyte.
•  The battery charging of the U3430, U4440 and U8410 devices will proceed at an indoor temperature ranging between 0°C and +40°C (the device has to be located in an indoor room with a relative humidity up to 85%). Fast charge mode can be run by turning off the device.
• Devices contain electronic components, it needs to liquidate them according to currently valid conditions
• To complement the information in this data sheet read the manuals and other documentation, which are available in the Download section for a particular device at www.cometsystem.com
