Digital noise meter model: HAD-HFZY-320

The HAD-HFZY-320 digital noise meter fully complies with the telephone weighted network recommended by the International Telecommunication Union (ITU) and is professionally used for measuring telephone weighted noise voltage in the power supply of program-controlled switches. It is an essential specialized measuring instrument for the maintenance and acceptance of program-controlled switches, long-distance communication equipment, and communication power equipment. The product has added an "automatic calibration" function, making testing more accurate and convenient.

◆ Product Features

• Portable:Traditional noise meters have a large volume and weight of approximately 10kg, making them inconvenient to carry for on-site testing; The digital noise meter weighs only 400g and is very portable.

• Digital:Directly displaying measurement values completely avoids the drawbacks of traditional pointer and desktop noise meters, where the pointer constantly drifts and swings, making it difficult to read accurate measurement values.

• Easy to operate:When measuring, there is no need to connect capacitor accessories in series, no need to adjust the gear, direct measurement, and simple operation.

• mVDual display with dBmThe instrument directly displays mV and dBm values to meet the needs of different users.

• Alarm function:When the measured balance noise exceeds the limit value of 2mV specified in the "Telecommunications Power Maintenance Regulations", the instrument will automatically sound an alarm.

• Calibration function:It can be automatically calibrated before measurement to avoid measurement errors caused by the accuracy deviation of the instrument itself (with an 800MHz standard source).
