Because uC is in TQFP package, we can program it after soldering all components on PCB. After that, programming is quite easy to perform. Programming signals are delivered through LCD connector. To make the programming cable, you can use an old PC HDD cable. Picture of my programming cable is shown here:

The next thing to do is to cross LCD soldering pads number 1 and 5. That’s necessary to provide ground for LCD RW signal. After all, connect LCD module with the multimeter PCB. It is recommended to use a detachable connector for further expandability e.g. software upgrading.

To regulate fine sub-range connect voltmeter to PSU output, set up voltage at about 9V and turn R9 until voltmeter and multimeter indications are equal.

To regulate coarse sub-range connect voltmeter to PSU output, set up voltage at about 19V and turn R10 until voltmeter and multimeter indication are equal. (If  you posses 4.5 digit voltmeter, you could regulate at voltage 30V)

Multimeter works properly with LCD’s 1×16 logical controlled as 2×8 (most of LCD’s available on the market).Because of linear voltage regulators used in multimeter, sourcing current is limited. Main current consumption elements are fan and LCD backlight, so:

Both analog voltmeter and analog voltmeter come in different types depending on the design and the user, the design is the same. On the other hand, analog voltmeter and analog voltmeter come in different sizes depending on the design of the user, and the design of the user.

Similarly, an analog voltmeter is used to display the monitor voltage tester as well. On the other end, an analog voltmeter is equipped with a monitor and voltage tester, and in this way, it can display various functions such as analog volt teter and analog voltage tester.

Sellers offer a wide range of analog voltmeter and Alibaba.com"s suppliers offer a wide range of products at bulk prices, so don"t miss out on this chance and start exploring today. Don"t miss out on the deals and find out more about what sellers offer at great prices on Alibaba.com.

When choosing a car battery, it is important to consider the amount of voltage that is relevant to the user. A analog voltage tester is used when choosing a car battery, and also provides the voltagemeter to any different consumers. For general consumers, the best anog voltage tester is used to pick the voltmeter, and it is important to consider what the device is best to use.
