protection is reduced to IP 20; therefore, do the charging under room (or similar) conditions only. If the battery is very low, the charging process may be terminated with an error message. In such a case contact the datalogger vendor to apply for battery replacement. During the battery charging period the internal temperature of the device may be slightly raised, which can, for a short period of time, adversely influence the measurement values of the internal sensors. -

Page 38: Application Notes
Application notes Operation with a constantly connected charger __________ Datalogger is primarily intended to be operated as an autonomous unit powered by its built-in batteries. Nevertheless, you can also operate it with a charger which is constantly connected to it, or with a computer. The datalogger’s internal charging circuitry controls the battery charging process based on its instantaneous condition, thus protecting it against damage. - Page 39 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 40 • If the blue diode does not start flashing at all, then the datalogger‘s radio section has not been activated at all. It may be caused by an improper setting: A non-functioning SIM card has been inserted, the SIM Card has been blocked because a wrong PIN has been entered, the alarm is not activated at all, no phone number is assigned to the alarm, and the like).

After turning on the modem, it should light up for a while (searching for the network), then flash more slowly (registering to the network), then quickly (sending data) and then turn off (completed).

Page 42: 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 43 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.
