Frequency Meter Kit 1 Hz to 50 MHz + Crystal Tester

Based on a pre-programmed PIC16F628A microcontroller, this compact frequency meter measures frequencies from 1 Hz to 50 MHz and tests crystals from 4 MHz to 40 MHz. It has a 5-digit LED display, a DC power plug, a selection jumper for frequency measurement or crystal testing, and a programming button that lets you add or subtract an offset value from the measured frequency. Supplied as a kit, complete with a clear plexiglass enclosure and a USB-to-DC-plug cable (to be used with a USB-output power supply). Power supply: 5 Vdc to 12 Vdc.

• Crystal oscillation frequency measurement: 4 MHz to 40 MHz
• Automatic frequency range switching (Hz, kHz, MHz): Yes
• Function programming button: lets you add or subtract an offset value from the measured frequency
