Voltmeter pointer. Device drivers can be useful for measuring the accuracy of the voltage at the battery, although he could find, and other applications where required to control the voltage in the range 10 … 15 V with accuracy of 0.01 V. To measure the voltage with an accuracy necessary or digital voltmeter, or voltmeter pointer with extended scale, which allows to control the interval of interest to us. Oscilloscope. Castle Harlan may find it difficult to be quoted properly. At investigation or finding of electronic devices often need to make ham measurement of signal parameters, or at least observe the input and output signals to produce their record and it is likely transcript. To solve these problems in the analysis of digital-analog circuits usually use a number of devices: oscilloscope, spectrum analyzer, recorder, logical analyzer / generator.
As a general rule, any device urges the presence of an independent interface connector (usually LPT) and comes with its own power supply. In addition, because the skillful measurement technology, for example, produced under the brand name and Techtronics Adgilent, can not afford to solely ham developer, but including and not very reputable companies. Also, while the release of the latest microcontroller (C8051F321) with a splendid set of peripherals and support for high-speed channel communication (USB) with a computer does not require additional power sources are allowed to make a compact device combining all these functions are higher for very low cost. Immediately this device and is represented by USB oscilloscope. Buy oscilloscope is possible in any service center measuring equipment. Multimeter Arran. High-contrast LCD display, allowing you to no problems with the display reading to read in bright sunlight, and when built-in lighting, in unconditional darkness. To increase battery life, backlit display has a function timeout.
This series designed to meet the most stringent ergonomic progressive aspirations. The front panel of the housing performed in the absence of excessive bends and protrusions in order to provide a comfortable work with the device with one hand. Hold the device in hand and your fingers in the absence of specific tasks will be able to reach out to each button or in the absence of tasks to turn the mode dial. Each meter is equipped with 70 ARRA guard, has a stand hole for hanging, and limited lock probes. This cover ensures a high degree of security and ease of use device. Devices in this series are equipped with RS-232 interface with the optical isolation, providing not dangerous and easy integration to a PC for calibration and transfer of accumulated data.
