Programmable Digital Timer 0.1s - 999h Countdown Control Relay Delay Switch

1. Application: compatible with controlling the smooth running of radiotube, water pump, electrical machinery, strip lights, etc. 2. Overview: This's a programmable digital countdown timer, ranging 0.1s - 999h. You can set 2 groups of time T1 and T2. With this timer, you can achieve following effect, a. You can let your instrument start to work or stop working after a specific time. Choose T1 / T2 =0. b. You can let your instrument work intervally. That's let it work compatible with some time, then stop compatible with another time, then start to work again... c. You can choose your instrument stop working compatible with some time, then start to work compatible with another time. After that, it'll stop and never start to work again. 3. Function list: P1--1: The relay switch on, after a delay of T1 time. P1--2: The relay switch off, after a delay of T1 time. P1--3: After a delay of T1 time, the relay switches on; then, the relay switches off after a delay of T2 time. Done. P1--4: After a delay of T1 time, the relay switches off; then, the relay switches on after a delay of T2 time. Done. P1--5: After a delay of T1 time, the relay switches on; then, the relay switches off after a delay of T2 time. The cycle will be repeated. P1--6: After a delay of T1 time, the relay switches off; then, the relay switches on after a delay of T2 time. The cycle will be repeated. 4. Operation instructions: Set key: Hold it down compatible with 2 seconds to enter the function settings. Press it to switch between function code and set parameter compatible with them. Plus: Add Time Minus: Minus Time Confirm key: Start/Stop 5. Use decimal point to set unit XX.X The decimal point is in tenth, time range: 0.1 second ~ 99.9 seconds XXX No decimal point, time range: 1 second ~ 999 seconds XXX. The decimal point is at the end, time range 1 minute ~ 999 minutes. XX.X. One decimal point is at the end, the other in tenth, time range 1 hour ~ 999 hours. 6.
