Page 10: Operating The Datalogger From The Keypad
Operating the datalogger from the keypad Displaying the device data Data memory occupancy - this display section offers information about the current condition of the free space existing in the data memory. The blinking of the Memory symbol indicates that the pre-set memory occupancy limit has been exceeded. - Page 11 Record status - offers information on whether the recording is ON and whether it is just running. A continuous recording with a preset interval is ON and running. The recording is ON in the device and it is running at present. This kind of display is utilized, when the record activity is dependent on the alarm or the external input condition.
- Page 12 Battery condition - this symbol provides overview information about the current battery charging condition. The charging is indicated by flashing one of these symbols. Battery conditions during battery operation of the device: Fully charged battery Partly discharged battery Heavily discharged battery Totally discharged battery, the device will be switched OFF.

Page 28: Setting Up The Device
Complete device setup can be performed by the aid of the COMET Vision user software (hereinafter SW). During configuration editing the device can work normally, nevertheless the access to some functions (record download, contemporary configuration editing by other users) is limited. - Page 29 General - Preferences _____________________________ In this panel you can choose the unit with which the device will measure the temperature (Default temperature unit °C/°F). With some devices the pressure unit can be chosen, too (Default atmospheric pressure unit). When the device does not measure the atmospheric pressure, but when it is necessary to know its value to measure some quantities (calculated humidity and CO ), the atmospheric pressure value must...

Record _________________________________________ The choices that are available in this panel serve to control the device‘s recording functions.
- Page 31 Channels_______________________________________ In this panel you can set all input channels. The assignment of the measurement value and its range to a channel is factory-set and cannot be changed. Supply a suitable name of the location to be measured for each channel and decide whether it will be switched on for measurement and for recording.

It remains to decide, whether the alarm should be indicated optically by means of a LED diode on the device (Optical signalling - LED) or acoustically (Activate internal acoustic signalling) Alarm events...
- Page 33 or a system alarm or an alarm originating from an exceeded memory occupancy limit occur, a red LED diode is flashing. Besides, an alarm may be signalled acoustically by a characteristic sound, which is repeated at regular intervals. If the device is connected to an external power supply, the acoustic signal is more intense than with battery power.
- Page 34 Alarm events - Memory occupancy___________________ Use this panel setting, if an overrun of the pre-set limit value of the data memory occupancy needs to be signalled. The signalling mode may be selected optionally as optical (by means of a LED diode) or acoustical.

Page 36: Application Notes
Application notes Operation with permanently connected USB cable _______ Datalogger is primarily intended to be operated as an autonomous unit powered by its built-in batteries. Nevertheless, you can also operate it with permanently connected USB cable. In this case the device is not protected against dust and water ingress, and, consequently, it cannot be operated in locations in which such ingress protection is required. - Page 37 USB equipment in the computer. This may be corrected by closing the COMET Vision utility program (including the communication service) and starting it subsequently. Restart the computer, if the above mentioned measure is not the proper remedy. Check whether new HID equipment will appear in Device administrator after the device has been connected to the computer.

Page 38: Recommendations For Operation And Maintenance
Recommendations for operation and maintenance Datalogger operation in several application areas________ Before putting the device into operation, it should be considered, if its usage is suitable for the intended purpose. In connection with this consideration the device‘s optimum settings should be determined. In the case that the device is part of a larger measurement system, instructions for its metrological and operational checks should be developed... - Page 39 Positioning of humidity sensors: The positioning of humidity sensors depends again on the application requirements. Humidity measurements in refrigerators without additional humidity stabilization can be very questionable. When the cooling is switched on/off, there may be significant changes in humidity in the range of tens of percent, even if the mean value is correct.

Charging time: Charging time depends on the current battery discharge level. Since the parasitic heat is generated when the internal battery is charging, the charging speed with the power on is deliberately slowed down to prevent excessive influence of measured values. If you want to charge the device as soon as possible, turn it off first. -
