Q:Time control switch itself is not how time to tune back?

Time control switch panel with school by health, first press the school by health, and then see whether the show is a flash, if the minutes before the flash, you press the clock school, and then by the minutes of proofreading.

Q:Do not know what is wrong by the shortcut keys, can not switch the layer sound and display button. Ask the old driver to tell.

Move the current time point to * seconds (any number of seconds you need to keep), adjust the value to 100 (or whatever you want the size), it will automatically record the key frame. Drag the current timeline to preview.

Q:For example, I use the IGBT circuit switch, using the same gate resistance and drive circuit. Then use it to make a normal working current only 1A off the external circuit off time And let a current up to 100A of the external circuit completely off the turn-off time, Will there be a big difference between the two times? Or that depends entirely on the drive part of the control of the gate G, CE voltage at both ends of the voltage is not much relationship?

IGBT is equivalent to MOSFET and GTR connector, and its turn on and off is similar to MOSFET. MOSFET is a unipolar switch, and GTR is a bipolar switch, so the turn-off of the IGBT is slightly different. When the gate voltage begins to fall, the voltage at both ends and the current flowing are constant. When the gate voltage drops below the dead-band voltage, the voltage across the IGBT begins to rise, and the current flowing begins to decrease. The time of this decline is related to the size of the current, the greater the current, the longer the time. But the IGBT has the largest current limit can be turned off, when the current exceeds a certain value, IGBT can no longer turn off, and the occurrence of the engine effect, this time IGBT out of control, the gate is no longer work, this is a unique phenomenon of IGBT.

Q:The most common switching circuit Ton-turn-on time open Toff-turn-off time off Ts-storage time Tf-fall time Tr-rise time Td-delay time

Transistor in the switch circuit in the open and closed, due to the existence of barrier voltage, will produce a certain time delay. Storage, rise, fall mainly produce some cross-distortion, so that the circuit load of electricity becomes unstable ... ...

Q:Red rice note3 how to set the switch machine time

In the Security Center> Power> Timing Switch> Timed Start and Timed Shutdown On> Set the power on and off time.

Q:JFT16 microcomputer control switch how to adjust the time

Press and hold the [clock] key while pressing the [school week] key to adjust the week, hold down the [clock] key 【school】 key while adjusting the hour, hold down the [clock] while holding down [school Key to adjust the minute

Q:With a SJ11 relay and normally open proximity switch to form a control circuit, to close the switch in place after a certain period of time after the cycle of work

"Circulation work" means "after the switch is in place after a certain delay time" to start work, and then return to the original position to start again? Then, "delay for a certain time" can be done by the time relay. So how long is it? Can you express your request accurately?

Q:Germany Germany West KG316T time control switch how to set the system time?

To set the system time method: such as to set, while holding down the clock +, the non-stop by non-stop beating time, minutes and week is the same way to operate!

Q:Is there a software that can record the time on the computer?

And shutdown batch (shutdown.bat) command as long as the start.bat in the "*** boot record ***" to "*** shutdown record ***" can, the rest unchanged. After the above two batch commands are done, enter gpedit.msc in "Run" in the "Start" menu, open Group Policy, and then click "Computer Configuration → Windows Settings → Script (Startup and Shutdown)", double click "Start", in the Properties dialog box, click "Add" button, and in the "Script Name" column fill in the "start.bat" absolute path, click "OK" button. Similarly set the shutdown script. This can be a switch machine to do an experiment, open the C: aaa.txt file, is not recorded you just shut down and boot time?

Q:The total switching time of the transformer on-load tap-changer is probably how much

The total switching time includes the excessive time, the excess time means that the on-load tap-changer switches from one splitter position to another splitter gear has an over-process, similar to the semi-detached state.
