0.56″ 4 Digital Red LED Digital frequency meter 20-9999Hz and counter Arduino Projects Robots NEW
Measure and verify either sine wave (or square wave) frequency or square wave pulses with this LED frequency/counter panel meter. Switch between counter and frequency modes, and input 1 or input 2 with a flip of the on-board dip switch.
The wide working voltage range and small size allows for use in automotive environments, while the 20 to 9,999 Hz readout offers measurement of 90% of the content in the audio band. A unique feature, when in the 0 to 9,999 pulse count mode, is manual reset with the wave of your hand in front of the display.
Specifications: • Power requirements: 7 to 26 VDC • Current draw: 50 mA (@ 12 VDC) • Signal input: 5 to 12 V • Responding rate: 1 second • Frequency range: 20 to 9,999 Hz • Frequency accuracy: 0.5% • Display resolution: 0.01 Hz (20 to 99.99 Hz), 0.1 Hz (100.0 to 999.9 Hz), 1 Hz (1,000 to 9,999 Hz) • Counting range: 0 to 9,999 • Dimensions: 79 mm (3.11″) W x 42 mm (1.65″) H x 25 mm (0.98″) D.
•Never feed the meter with a voltage of higher than 26V DC, otherwise the meter will be burned out.
•Incoming signal which is running lower than 20Hz will make the meter display instable, so make sure the signal is running above 20Hz
