Use the latest M328 version software, more function than M8 version. The microcontroller adopts 8 MHz external crystals oscillator, better measurement accuracy.
The related resistance of affecting the accuracy use 1?metal film resistor, and the rest also use 1% metal film resistor.
Use backlight low-power consumption LCD screen, compared with the overall power consumption is almost negligible, convenient to read the data in the dark.
Up to two Resistors are measured and shown values with up to four decimal digits in the right dimension. All symbols are surrounded by the probe numbers of the Tester. So Potentiometer can also be measured. If the Potentiometer is adjusted to one of its ends, the Tester cannot differ the middle pin and the end pin.
Capacitors with value below 30pF are usually not be detected, but can be measured together with a parallel diode or a parallel capacitor with at least 30pF. In this case you must subtract the capacity value of the parallel connected part.
