Specification
Brand : Hperu
BulletPoint1 : LED frequency tester kit can measure the frequency range from 1 Hz to 50 megahertz (1Hz-50MHz), can measure the oscillation frequency of most common crystal oscillators, and measure equipment such as radio transceivers
BulletPoint2 : Five digital display, easy and intuitive, all use of in-line components, the circuit is simple and easy to produce
BulletPoint3 : This is a microcontroller based on the frequency meter, with a crystal measurement function and programmable addition and subtraction frequency settings
BulletPoint4 : The power supply can use a USB to 3.5mm power cable, or you can directly input a 5-9V DC power supply at the - and + pads
BulletPoint5 : Frequency counter kit can select energy-saving mode, it will turn off the display if the frequency is not changed in 15s

ProductDescription : Description

You need to solder and assemble by yourself, all the components are directly inserted, and the wire is printed correctly according to the PCB. After welding, the is input with the standard source, and the yellow adjustable capacitor is adjusted to make the display value equal to the frequency.

Features
Frequency counter kit
-Color: As Shown.
-Material: ABS.
-Size: 25x15 cm/9.84x5.91 inch.
Specifications:
Five precision resolution (eg 0.0050 kHz, 4.5765 MHz, 11.059 MHz);
Automatic range conversion, without human switching;
Programmable addition and subtraction frequency settings for the measurement of radio transceivers and other equipment;
You can select the power saving mode, if the frequency is not obvious changes within 15 seconds automatically turn off the display;
You can use the universal USB 5V interface power supply, can also use an external DC power supply or 9V battery.
The number of components is small, all straight-line components, installation and commissioning simple.
Crystal measurement (4M, 16M crystal).
Crystal measurement (20M, 11.0592M crystal oscillator).
32.768KHZ crystal oscillator can not be measured, the conditions are limited, only 4-20MHZ crystal can be measured, 48MHZ can also be measured, but because this crystal is using 3x harmonics, 48MHZ crystal measurement will show the fundamental frequency 16MHZ.

Note:
Manual measurement, with small error. Please check size in detail before purchase.
Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness.
