HZ210 is a small frequency meter that can measure low frequency and high frequency signals.

This module is simple to use and selects different testing methods through key operation.

Two. Product application:

Measurement of pulse frequency;

The frequency of radiofrequency is measured.

Three. Technical parameter table:

Serial number project parameter unit notes

1 measurement of low frequency range 1Hz ~ 8MHz Hz

2 measurement range of low frequency voltage from +/-0.7V to +/-15V

3 measurement of low frequency resolution 1 Hz

4 measurements of high frequency range from 2MHz to 2.0GHzHz

5 measurement range of high frequency voltage from +/-100mV to +/-5V

6 measurement of high frequency resolution 1KHZ Hz

7 working voltage 7~12 VDC

8 working current <50 mA

9 working temperature -40 C ~ 65 centigrade degrees centigrade

10 storage temperature -40 C ~ 65 centigrade degrees centigrade

11 size 57*50*20 mm long X wide X height

Note: the low frequency signal is not an AC signal, and a 1OuF capacitance measurement is connected in series at the input signal end.

The low frequency signal is a DC coupling. In order to exchange coupling, please measure the capacitance in series.
