Fast delivery by airmail Battery backed-up, DS1307 RTC (real time clock) will stay right on time, set the time once and forget it supply: standard 5V USB charger or computer port (Power supply not included) - digital accuracy correction - Measured temperature -55.0 ÷ 125.0 ° C - indication alternately. (Time, temperature) - customizable animation change of indication. - use of non-volatile memory of the microcontroller to save settings when the power is turned off. - if you press the PLUS button in the main mode, the time is displayed on the indicators - if you press the MINUS - temperature. When the buttons are released, the automatic change of readings resumes. - When the power is turned on, the clock is in basic mode. Settings- Pressing the MENU button enters the setting mode and selects a group of parameters to set. Within the group, select the parameter for setting by pressing the SET button. In turn, they are available for installation: CLOCK Group: - minutes; - hours; - seconds (reset when you press PLUS or MINUS); - the value of the daily correction of time. The symbol "c" is in the upper digit. diSP group: - Time of the current time indication. The symbols "tc" are in the upper digit. Setting range 0 ÷ 99 sec. If 0 is set, the time will not be displayed; - Time of temperature indication. The symbols "tt" are in the upper digits. Setting range 0 ÷ 99 sec. If 0 is set, the temperature will not be displayed; - Select the effect of the animation. The symbols "EF" are in the upper digits. If 0 is set, the information will be changed without effects, if the automatic mode ("A" symbol) is selected, the effects will be alternately changed. If the "r" mode is selected, the effects will be changed randomly. - Select the speed of the animation. The symbol "P" is in the upper digit. Setting range 0 ÷ 99. One unit corresponds to approximately 2 msec, the higher the value, the slower the animation. The backlight is turned off by removing the jumper.
