User manual IROX HRT407

[. . . ] Weather forecasts by Jörg Kachelmann: www . meteocentrale. ch The HRT407 is a high-quality thermo/hygrometer that gives you the absolutely unique feature of choosing between three different max/min memory functions. They contain some useful and interesting information that go beyond a mere explanation of how to operate the device. Full-segment display Comfort Zone: - display of the comfort status of the measurement of the thermo/hygrometer Thermo/hygro : - temperature and relative air humidity of the display device (measures at the location where the device is used) - memory values min/max of the thermo/hygrometer - battery status of the display device 25 26 2. 2 KEYS / SWITCH / BATTERY COMPARTMENT Rear view Pos. 2: 24 Hr - If you choose this option, the MIN/MAX values for the last 24-28 hours in each case are recorded. After expiry of this period, the MIN/MAX values that are older than 24-28 hours are removed from the memory. [. . . ] As soon as you have selected this option, we recommend that you start the memory recording in a defined way with a MEMORY RESET. This then starts a recording that triggers internally an elaborate calculation and recording. Example: You want to be able to read the MIN/MAX values of the last 24-28 hours at all times. Irrespective of when you look at the display, you will always see the extreme values of the last 24-28 hours. 3: DAY- If you select this option, the MIN/MAX values are recorded for 24 hours in each case. The start is determined by a MEMORY RESET and after 24 hours, the memory is automatically reset and a new recording begins. Example: You want to be able to read the MIN/MAX values of the last 24 hours in each case at 8 p. m. With this RESET, the clock begins to tick internally and this automatically resets the memory after 24 hours and starts a new recording. °C/°F - Changes the unit of temperature in the display from °C to °F or vice versa Battery compartment MEMORY RESET - Hold pressed for 3 seconds: Resets all memories. The new recording now begins depending on the setting of the MIN-MAX switch MIN-MAX The MIN/MAX memory is managed and recorded depending on the setting. - LEFT: Minimal (=lowest) temperature "MIN" - RIGHT: Maximum (=highest) temperature "MAX" The logic of the recordings is displayed in Section 2. 2 Operating elements. 29 30 6.
