HZ211 Small Frequency Meter High Precision Pulse Accumulation Counter for Frequency Meter 1Hz-2.7GHz

I. Overview: The HZ211 is a small frequency meter that can measure both low and high frequency signals. The module is simple to use, through the key operation, select different test methods. Second, product application: ● Measure pulse frequency; ● Measure RF frequency; 3. Technical parameter table: No. Item Parameter Unit Remarks 1 Measurement Low frequency range 1Hz ~ 8MHz Hz 2 Measure low frequency voltage range +/-0.7V ~ +/-15V 3 Measure low frequency resolution 1 Hz 4 Measure the high frequency range from 1MHz to 2.7GHz Hz 5 Measure the high frequency voltage range from +/-100mV to +/-5V 6 Measure high frequency resolution 1KHZ Hz 7 Operating voltage 7 ~ 12 VDC 8 Working current <50 mA 9 Operating temperature -40℃ ~ 65℃ Celsius 10 Storage temperature -40℃ ~ 65℃ Celsius 11 Dimensions 57*50*20 mm long X wide X high 12 Weight 50g Note: The low frequency signal is not an AC signal, and a capacitance of about 10uF is measured in series at the input signal end. Measurement of low frequency signal is DC coupling, to AC coupling, please measure the capacitance in series. 4. Interface description and related operations P1 interface (Power supply) VDD: positive power supply (7 ~ 12V) GND: negative power terminal P2 interface (low frequency input signal) FX: Detects the low frequency input signal. GND: negative power terminal. P3 interface (high frequency input signal) RF: Detects high-frequency input signals. GND: negative power terminal. 5. Key description FUN: Select (high frequency/low frequency) measurement method MODE: Clear the display unit/counter. 5.1, low frequency measurement Interface display font: First line "1.FX = 12MHZ" The second line "00000000Hz" Key operation: MODE: Select a display unit. 5.2, high frequency measurement Interface display font: First line "2.RF = 2.7GHz" Second line "0000.000MHz" Key operation: 5.3, cumulative counter (measuring maximum frequency 100KHz) Interface display font: First line "3.FX = Counter" The second line "00000000n" Key operation: MODE: indicates that the counter is cleared.
