Inspect the sentries operation, operation and the cardinal principle of instrument of this computer is such: plug in, show the display screen 1S(24 of time) promptly show 12:01, and, at this moment click button 3A(31 with the 2Hz frequency scintillation), make its operate as normal.
Period of inspecting the sentries is provided with:
One, the time that begins to inspect the sentries is provided with: pin button 4A(32), at this moment display screen 1S(24) show that (upper left corner is red to light up as the morning to the 12:00 printed words, the lower left corner is red to light up as afternoon), 2A(30 then touches the button respectively) during the school, 3A(31 touches the button) the school branch, make the required time of inspecting the sentries that begins of its demonstration end.
Two, the termination time of inspecting the sentries is provided with: pin button 1A(29), operate with quadrat method by top then.
Digital dock 2IC(10) have two warning functions, begin the time of inspecting the sentries to arrive, its 26 pin output signal stops the time of inspecting the sentries to arrive its 1 pin output signal.
The check and correction clock:
One, check and correction: press the button 2A(30), make display screen 1S(24) " hour " show that the real time ended at that time.
Two, school branch: press the button 3A(31), make display screen 1S(24) " branch " show that at that time the real time ends.
The adjustment in week: inching button 5A(33), following two conditions of order satisfy simultaneously ends: the Sunday in week that display screen 2S(25) demonstrates the same day; The pilot lamp LED of inspecting the sentries
1(37) light on and off should match with the period of whether inspecting the sentries of living in.
K switch
1(27) use: K switch
1(27) for interrupting inspecting the sentries switch improper holiday, interrupt when pulling (promptly pulling 2 positions) inspecting the sentries; Carry out the program of inspecting the sentries when pulling down (promptly pulling 1 position).
K switch
2Using (28): this switch is unit holiday, can interrupt the switch of inspecting the sentries automatically, the program of inspecting the sentries when pulling (promptly pulling 2 positions) and other Sunday with; Pulling down (promptly pulling 1 position) unit stops to inspect the sentries Sun. automatically.
Month, day are proofreaied and correct and are used: press the button 6A(34), display screen 1S(24) show month, day, if will proofread and correct, 2A(30 touches the button) the school moon; 3A(31 touches the button) school day (when having this function, the dotted portion circuit does not connect among Fig. 1).
Computer is inspected the sentries instrument after entering the time of inspecting the sentries, and the signal generator of inspecting the sentries at random (3) is started working, and the time of sending of the signal of inspecting the sentries for the first time is by channel to channel adapter 5IC(13) resistance R of 13 pin passages
