智能電子鐘的功能：
1。 全日歷計(jì)時(shí)。
2。 12/24小時(shí)轉(zhuǎn)換。
3。 8路定時(shí)輸出（可關(guān)/開(kāi)控制）
4。 誤差：15S+1uS
5。 大、小月，潤(rùn)年，周，自動(dòng)追蹤
二、 調(diào)校：
上電后，電子鐘顯示“1：00”。
1。 8路定時(shí)時(shí)間查詢
按下K1鍵依此顯示8路定時(shí)時(shí)間。星期位顯示：“H”表示：打開(kāi)當(dāng)前定時(shí)輸出；“L” 表示：關(guān)閉當(dāng)前定時(shí)輸出。此時(shí)按K2鍵可進(jìn)行“H”、“L”的切換。所有輸出，均由蜂鳴器輸出！
2。 顯示狀態(tài)的控制
按下K2鍵可進(jìn)入以下工作狀態(tài)：
1）12小時(shí)/ 日月交替顯示。
2）12小時(shí)固定顯示。
3）24小時(shí)/ 日月交替顯示。
4）24小時(shí)固定顯示。
3。 校時(shí)
按下K2鍵3S后，進(jìn)入校時(shí)菜單。按下K1鍵依次進(jìn)入校時(shí)狀態(tài)：分、時(shí)、天、月、年、微調(diào)系數(shù)。此時(shí)按K2鍵，完成+1。當(dāng)顯示“d”時(shí)，表示要調(diào)整微調(diào)系數(shù)（0-99），其值越小，時(shí)鐘走時(shí)越慢。當(dāng)使用的6MHz的晶振偏差大時(shí)，應(yīng)仔細(xì)調(diào)整微調(diào)系數(shù)！當(dāng)顯示“out”時(shí)，按K2鍵，即可退出！退出后，按任意鍵即可啟動(dòng)時(shí)鐘。
4。 設(shè)置定時(shí)時(shí)間
按下K1鍵3S后，進(jìn)入設(shè)置菜單。按下K1鍵依次進(jìn)入8路定時(shí)調(diào)整狀態(tài)：時(shí)、分。此時(shí)按K2鍵，完成+1。當(dāng)顯示“out”時(shí)，按K2鍵，即可退出！
