Some notes on using a mini multimeter

Multimeter is a commonly used instrument of electrician. Gives us a great help in the time of maintenance. Of course, it is so widely used, but some wrong operations will damage your multimeter. So what we need to pay attention to our mini multimeter in daily life? Then I would simply tell some relevant considerations for you.

Before using a mini multimeter, should be adjusted to set zero for mechanical, it means that when measured in the absence of electricity. The multimeter pointer refers to the location at zero voltage or zero current. In the process of using a multimeter, you can not touch the metal parts of pens. So that you can ensure accurate measurements, on the other hand, can also ensure personal safety. When using a multimeter, in order to avoid errors, it must be set horizontal flat. At the same time, avoid the influence of external magnetic field. After using multimeter, should be switched in the biggest block of AC voltage. If not use it long term, it should be taken out internal battery from multimeter, avoid the battery corroding other components.

When measuring a power, can not shift gear in the time of measuring the power, especially should be noted in the measurement of high or large voltage. Otherwise, it would destroy the mini multimeter. If you want to shift the gear, please disconnect the leads, and then to measure after switching. Also need to note that when using multimeter, the red pen should be inserted in the “+” hole, the black should be inserted in “-” hole. Testing current must use the current stall, do not misuse voltage division, resistance gear, etc. Otherwise, the multimeter’s fuse would be burning inside, even damage the meter heavily. I hope you can read these notes before using your mini multimeter.

Pickit3 programmer, boutique design, simulation development

Pickit3 programmer is one of development tools which Microchip provides for beginners to learn, evaluate, develop the series of PIC. It integrated the online emulation and downloading. The MCU, series of PIC, can use the interface of ICSP to connect to Pickit3. As it integrated environment of developing software, can directly support for official IDE of Microchip. Also support for all MCU of PIC with the interface of ICSP. Really allows us to be assured to be developed.

Pickit3 programmer has four features. First, the programming function can programming FLASH ROM, EEPROM, etc. Second, simulation capability supports all kinds of debugging methods, such as full speed debugging, single-step debugging, breakpoint debugging and so on. Third, simulation performance: it uses the USB interface for simulation debugging with a fast response on step debugging and breakpoint debugging. Fourth, program performance: using the USB interface, makes ICSP downloaded with a high speed. Furthermore, the USB interface is strong and wearable, can prevent the unrecognized by the computer in the status of USB relaxation. The USB connection of Pickit3 is stable and reliable than ICD2, did not often appear the problem which ICD2 unconnected to the computer.

You will never worry about Pickit3 programmer losing firmware. When it is not connected to the computer, all the lights lit, and the computer does not recognize kit3. You can use the self-recovery function of firmware. It supports for one key repair firmware. In the future, Microchip will release more models of PIC and will add these new modules into the supported devices list of ICSP. When you need to use the new modules for developing in the future, you can upgrade the firmware of Kit3, would have to be supported by new models. In addition, the upgrade is automatical. The Microchip will provide the process of prograde for us. It really helps a lot on developing.
