The digital multimeter is a rapid, accurate voltage, current and resistance tester, with a concise design on the front panel that enables you to quickly get the required measurement function. And the satellite finder is designed to help the user to quickly and accurately align the antenna to the best position.

Digital Multimeters

GAOTek offers a wide selection of high quality and affordable digital multimeter. Multimeter or volt-ohm milliammeter (VOM) is a measuring instrument that blends multiple measurement functions into a single unit. These devices can measure voltage, current, and resistance. Analog multimeters use microammeter with a moving pointer to show readings. Whereas, digital multimeters (DMN, DVOM) have numeric display and sometimes have graphical bar to represent the measured value. Currently, digital multimeters are more common due to its precision and cost, but analog multimeter is still more preferred when monitoring a rapid varying value.

Functions

Modern digital multimeters have a wide range of usability to suit most engineers’ needs. All multimeter perform the basic 3 functions for measuring voltage, resistance and current. However, there are meters able to further measure capacitance, frequency, temperature, transistor specifications, etc. The multimeter is one of the most useful instruments to use for testing electrical circuits. The device enables the user to:

  • Measure voltage in AC and DC circuits
  • Measure current flow AC and DC circuits
  • Measure resistance of the complete circuit or individual components
  • Measure transistor gain
  • Perform diode tests

Features

GAOTek’s durable and portable multimeters have important features to ensure the users to have an effective and efficient experience during operation. The important features include the ability to select a range voltages, the ability to measure AC and DC voltages, and the ability to measure ohms. Some of these devices come with temperature probe which is useful for working with PCs to determine how hot the processor is. Additional features include the ability to measure AC and DC amperage, and to test capacitors and transistors.

Industries and Applications

The handheld device is useful for basic fault finding and field service work, because it can measure to a high degree of accuracy. Moreover, they support troubleshooting electrical problems in many industries and household devices such as motor controls, domestic appliances, wiring systems, power supplies, and electronic equipment.

Digital Satellite Finders

GAOTek offers a wide range of high quality and affordable satellite finders and meters which are made to assist with quick setup of satellite dishes and LNBs to the best position. These portable devices have built-in satellite tuners which allow users to view FTA stations and evaluate their quality. In addition, GAOTek’s satellite finders empower users to choose and verify equipment.

Functions

Satellite finders and meters have large modulate range to help with TV signal clarity. These devices offer BER, signal quality and signal quality sign, and furnish blind scan function with numerical perusing and bar perusing. Satellite finders have A/V info permits associated with CCTV cameras that are useful in video observation frameworks. Satellite finders can be utilized for DVB-S/S2 and ABS-S signal estimation with top-quality shading LCD screen. The satellite finders can help users to  set the central length and the center of every camera. They can be used to find the satellite signal, enhance the television signal and reduce the TV noise.

Features

Satellite finders have sound and light alerts for detecting signals. Satellite finders and meters are considered as single channel per carrier (SCPC) and multiple channels per carrier (MCPC), capable.Moreover, they are quadrature phase shift keying (QPSK) at the front end. These devices can store the measurement data in the internal memory for later quality comparison. Satellite finders and meters can be upgraded by utilizing USB flash disk and RS232 port. Satellite finders and meters have multi-language interface and can be operated by LNB. The devices support numerous sorts of LNVs that are controlled by using a blend of 22k switch and digital satellite equipment control. It supports a varying sorts of frequency ranging from 950 MHz to 2150 MHz with -65 dBm to -25 dBm signal. Lastly, it has an auto shutdown feature for LNB cut off, and can be used for long period of time due to its high limit Ni-MH and Li-ion batteries.

Industries and Applications

GAOTek’s satellite finders and meters can quickly and accurately align the satellite dish, and instantly check the stability of the channels. Moreover, the user can modify the Transponders, frequency, symbol rate, polarity, and other settings. Satellite finders are widely used in wireless, data, and PSTN networks.
