User manual IROX JKT-3R

[. . . ] Weather forecasts by Jörg Kachelmann: www . meteocentrale. ch The JKT-3R is a high-quality thermometer that gives you the absolutely unique feature of choosing between three different max/min memory functions. The recording is done independently for each of the 6 channels in total. The individual scanning of the 5 radio sensors also makes operation transparent and calculable. They contain some useful and interesting information that go beyond a mere explanation of how to operate the device. Full-segment display Radio channels 1-5: - current measurement of the selected channel (=radio probe) - memory values min/max of the selected channel - battery status of the sender displayed Indoor thermometer : - temperature of the display device (measures at the location where the device is used) - memory values min/max of the indoor thermometer - battery status of the display device 29 30 2. 2 KEYS / SWITCH / BATTERY COMPARTMENT Rear view MIN-MAX The MIN/MAX memory is managed and recorded depending on the setting. [. . . ] Directly after the activation of the batteries, all segments are displayed for a few seconds on the display. The JKT-3R then begins with the search of available sensors on all 5 channels. As soon as the sensor is displayed correctly (see `Reception status' in Chap. , 4), you can set up the sensor in the place where you want to effectively measure the outdoor temperature. Under the most ideal conditions, this can be up to 30 m away. In reality, however, this is often less. In the event of problems, try out other places, and do so both for the sensor and for the display device. Nevertheless, please place the sensor where possible in the dry and at any rate in the shade. If you would like to display further sensors on the reception device, you can purchase these from shops. For outdoor use, we recommend weatherproof sensors. If you would like to display other interior spaces, the sensor JKR-1 from the `Instruments by Jörg Kachelmann' range is available in the same design as that of the display device and also has a large display. Reception status display The wave symbol indicates the status of the signal reception of the channel displayed. Temperature readings are securely registered. No signals. 33 34 Start search process for a sensor Select the desired radio channel with the CHANNEL key. Example: Channel 4 (the number 4 is flashing) Signal `collisions' Radio signals of other devices in their environment can cause disruptions or temporary interruptions in reception. This is not bad but could be annoying under certain circumstances. Such typical 'disruptive systems' are radio door bells, wireless security systems, tube screens (PC/TV), control systems, etc. In such cases, it can also be helpful to use another channel. Now press and hold the SEARCH key until the wave symbol starts to flash. The device now searches for the sensor on channel no. This process can take a few minutes and is finished as soon as the wave symbol stops flashing. We have deliberately ensured that the search channel can be individually called up per channel so that sensors that are already logged in are not affected by subsequent enhancements. 5. OPERATION 5. 1 THERMOMETER The JKT-3R measures the temperature directly and also receives the measurements of up to a maximum of 5 IROX radio temperature sensors. Each sensor is to be set to one of the channels 1-5 (resp. 1-3 for 3-channel devices). The temperature currently measured is displayed in the information windows in °C (or °F). [. . . ] - LEFT: Minimal (=lowest) temperature "MIN" - RIGHT: Maximum (=highest) temperature "MAX" The logic of the recordings is displayed in Section 2. 2 Operating elements. Please note: Lines appear if no data are available. This occurs when a channel is not allocated or the sensor is no longer being received. 6. CHANGE OF BATTERY : BATTERY CHANGE DISPLAY The batteries last for around 8-12 months. [. . . ]
