MATRIX: 128 x 64 dot matrix LCD, display 5 digital reading. Can use mirco usb as external power.
Description
Please Note:Accuracy may be affected by the test lead's length and distance, especially for testing pF small capacitance. Shortest test lead is recommended,
and be careful the surrounding EMI or RF noise may affect the pF reading.
Please discharge the capacitor before testing. You can use a screwdriver to short circuit or series with a resistor around 10ohm and short for 5
to 10s. There is one fast zener diode inside the meter to prevent high voltage, but it is important to discharge the capacitor firstly as it has large
surge current and voltage, which may damage the meter.
