For the RF ThermaData Logger; over the range -40F to +257F [+185F for an internal sensor] with a resolution of 0.1F and an accuracy of 0.5F, although with trim (by the user) the accuracy can be improved. The sample interval can be set anywhere from 1 minute to 255 minutes in 1 minute steps. It can also be programmed with a Start Delay from 1 second to 23 hours, 59 minutes. Alarm settings can be programmed into the RF ThermaData Logger for Over Temperature and Under Temperature. These would normally be set to levels acceptable for the environment in which the unit is recording. The LEDs will flash at 12 second intervals, with a green LED indicating that the temperature has not gone outside the alarm levels, and a flashing red LED indicating that an alarm has occurred. For a more detailed description see the Button and LED indicators section. User identification can be entered into the RF ThermaData Logger to aid the use of multiple loggers; up to 32 characters can be stored within the logger as the ID. This ID is case sensitive and can take any characters except the following
The RF ThermaData Logger can also store trim data for improved accuracy. This feature can be password protected for security. The password is case sensitive and can be any characters except the following
The RF ThermaData Logger can store up to 8000/16000 readings at any time. It can be set to stop recording once the internal buffer is full, or to loop back to the beginning and overwrite the oldest data (oldest data will be lost as it is overwritten). The RF ThermaData Logger interface buttons provide the ability to perform the following functions: -

Electronic Temperature Instruments Ltd Easting Close, Worthing, West Sussex BN14 8HQ tel: 01903 202151 fax: 01903 202445 specialists in the design and manufacture of temperature measuring equipment Battery Replacement Note: Removing the battery will NOT cause all stored readings to be lost. The RF ThermaData Logger internal battery has a minimum expected life of 1.5 Years. A battery level indicator in the application software will indicate the approximate battery level when the logger is accessed. If the battery expires the application software will inform you next time you attempt to access it. The RF ThermaData Logger is constructed from a two-part case. The case can be opened by unscrewing the three retaining screws and removing the rear case. The screws are retained by rubber seals (ensure these are not lost). Once the case is apart the battery can be seen and removed manually. When removing the battery, it is important to note the orientation and polarity. The battery compartment is marked with the polarity for the battery. It is recommended that only Tadiran SL750 batteries supplied by ETI Ltd are fitted. However if fitting a third party battery, fit only an inorganic lithium battery with a specification of 3.6V, AA size that has an operational temperature range equal to or greater than the ThermaData Logger (-40 to +185F). Fitting a third party battery may lead to a significant reduction in the battery life of the instrument. Be sure to fit the battery in the correct orientation. The battery compartment will have a + and a - sign, the battery will have at least a + sign. These symbols must be aligned for correct polarity. Once the battery is fitted correctly, replace the rear case, and screw the screws in two turns. Stretch the seal (with the narrower lip towards the rear case) over the case and allow the tongue to drop into the gap between the case halves. Once in place tighten the screws fully; but do not over tighten. Once the battery replacement has been completed a factory reset is advised. Any readings that were stored in the logger memory will be retained; these may be downloaded before a factory reset is performed. To perform the factory reset, connect the RF ThermaData Logger and select the Factory reset function (see relevant help section).

The reed switch, in conjunction with a magnet, is used initially to Start the logging (can also be started from the PC software). The magnetic start is performed by touching the smaller end of the magnet fob flat against the rear of the logger, over the magnet symbol on the rear label. From the point at which the start is requested the Start Delay is initiated, after the required delay, the RF ThermaData Logger starts taking samples at the specified interval (the start instruction is acknowledged by both the red and green LEDs flashing together 4 times). After the RF ThermaData Logger has started logging, the LEDs will flash automatically to indicate the log alarm status. Below are descriptions for the possible LED signals:
Red & Green LEDs Flash together (four times) The RF ThermaData Logger has received a Start instruction, and acknowledges that the start delay has been initiated (after the start delay logging will start at the specified sample interval). Red & Green LEDs Flash alternately (four times) The RF ThermaData Logger has started, but not yet taken its first reading. This could be due to the Start delay, or the interval for the first sample has not yet elapsed. Red LED flashes (once every 12 seconds) The RF ThermaData Logger has been taking samples and at least one of the samples taken is outside of the specified Over / Under Temperature alarm levels. Electronic Temperature Instruments Ltd Easting Close, Worthing, West Sussex BN14 8HQ tel: 01903 202151 fax: 01903 202445 specialists in the design and manufacture of temperature measuring equipment Red LED flashes twice (once every 12 seconds) The RF ThermaData Logger has been taking samples and at least one of the samples taken was outside of the specified Over / Under Temperature alarm levels, but the samples being taken have now returned to within the alarm levels.
