This is a frequency meter based on PIC microcontroller with quartz oscillator measurement function and programmable plus and minus frequency settings, five-digit digital tube display, practical and intuitive, all use directly plug-in components, simple circuit, easy to make. Five-digit precision resolution (for example, 0.0050 kHz, 4.5765 MHz, 11.059 MHz); automatic range conversion, no manual switching required; The oscillation frequency of the most commonly used quartz oscillators can be measured; The measurable frequency range is 1Hz-50MHz; Programmable plus and minus frequency settings for measuring radios and other devices; › See more product details; Product description Cvoepobey The power saving mode can be selected and the display will automatically turn off if the frequency does not change significantly within 15 seconds; The power supply can be provided via a universal USB 5V interface, external DC power supply or 9V battery. The number of components is low, all components are directly pluggable and installation and troubleshooting are easy. The 32.768 kHz quartz oscillator cannot be measured. Due to limited conditions, 4-20MHz quartz oscillators can be measured. The 48 MHz quartz oscillator can also be measured, but as this quartz oscillator uses the triple harmonic frequency, the base frequency of 16 MHz is displayed when measuring the 48 MHz quartz oscillator. You can also enter the frequency signal directly between IN and G (ground) for measurement. Note that the measured signal amplitude should not be as 5V to avoid damage to the IC. Tips: The product can be updated constantly. Due to different batches, the actual product may have slight differences or colour differences that do not affect the use. The parts are supplied individually and must be welded and disposed of by yourself. Color: photo color Material: PCB Package contents: 1 x frequency counter kit. Only the above package content, other products are not included. Note: Due to the light reflection and monitor settings, the colour of the item in the photos may be slightly different. The allowed measurement error is +/- 1-3 cm.; Product description Cvoepobey The power saving mode can be selected and the display will automatically turn off if the frequency does not change significantly within 15 seconds; The power supply can be provided via a universal USB 5V interface, external DC power supply or 9V battery.
