When I first entered this forum, I would like to dedicate all my practical DIY production to everyone, first on the Supermicro Simple Multimeter.
Everyone may have a few pieces, but the ultra-micro multimeter is broken, and it doesn't hurt. (The cost is too low.) This ultra-super multimeter is suitable for emergency use. There is only one equivalent of 1K and another 30V. DC block (changeable voltage block)
Material: 1 shell, 1 small head, 2 resistors, 1 1.5V battery, 2 test leads, 2 jacks or 3 foot switches.
Power-blocking: 1.5V battery string resistance and meter head, change the resistance to straighten the head to the full gear, measure several resistors and mark the position of the hands, when you use it, you can judge the resistance value Blocked. It saves a battery for one year without problems.
Adjust the voltage block: the external voltage string resistance into the meter head, change the resistance is the position of the meter pin, (such as: to do a 25V block, use 5V power to access, adjust the resistance value to make the hands to 1 grid. 2 squares when measuring It is 10V, and 3 is 15V.
As long as you have a smaller head, the player has a small battery and uses a micro 3-pin switch to switch the resistance voltage. You can make a micro-super multimeter that is smaller than half of me.
24 hours mechanical timer
Instant indicator
Min.setting time:15 minutes. Max.setting timer:24 hours
With hand switch,can be switched to operating and
setting at any time
Instructions:
1. Set program: 1 pin is equivalent to 15 minutes. Determine desired start time and push down pins until desired
off time.
For instance, if you want electrical devices to work from 8:00am to 11:00am and from 13:00pm to 17:00pm, you
just need to put down allthe pins between the three period time.
2. Set the current time: Turning the dial clockwise until the arrow pointing to
current time.
For example,if now it is 8:00 am, please turn the dial and make sure the
arrow point to 8. (See the picture.)
3. Plug the electrical device directly into the timer. Make sure the electrical
device is power-on.
4. Plug the timer into electrical outlet and the electrical device will be work
according to the setting program.
Note: = Normal Ope n = Timing
Make sure the switch on the Timing position. If it
is on the [Normal Open" mode, the electrical device is
always power-on and the timer function no work.

Application:
1. To enable high-power electric appliances to run automatically at off-peak time if there is different electricity
price according to different periods of time in some areas.
2. To use for electric appliances which need time control, such as water heaters, air conditioners, drinking
fountains, rice cookers, advertising lights and so on.
3. To control the charging time. For example, battery of electric bikes or mobile phones, storage batteries, etc.
4. Occasions which need switch on/off frequently, like interval spray irrigation for flowersand lawn, cyclical
adding oxygen to fish jar, fountains and so on.
5. Home safety precautions and lighting.
Caution:
1.D o not exceed the maximum ratings of the timer.
2.M ust reset the current time after power failure.
3.D o not plug the timer directly into the working electrical appliances.
4.U nless changing the setting, keep the program same every day.
5.D o not disassemble timer by yourself. Professionals service are needed for maintenance.
6.T his item is only for indoor use.
