I. Overview:
HZ210 is a small frequency meter that can measure low and high frequency signals.
This module is simple to use, and can be operated by pressing keys to select different test methods.
Product application:
● Measuring pulse frequency;
● Measuring radio frequency;
Third, the technical parameter table:
Serial numberprojectparameterunitRemark
1Measuring low frequency range1Hz ～ 8MHzHz
2 Measure the low-frequency voltage range +/- 0.7V +/- 15V
3Measuring low-frequency resolution1Hz
4Measuring high frequency range2MHz ～ 2.0GHzHz
5 Measuring high-frequency voltage range +/- 100mV ～ +/- 5V
6High-frequency resolution1KHZHz
7Operating Voltage7 ～ 12VDC
8Working current<50mA
9Operating temperature-40 ℃ ～ 65 ℃Celsius
10Storage temperature-40 ℃ ～ 65 ℃Celsius
11size57 * 50 * 20mmLength X width X height
Note: The low-frequency signal is not an AC signal, and a capacitor of about 1 OuF is connected in series at the input signal end.
The low-frequency signal is DC-coupled. For AC-coupling, please measure the capacitance in series.
