Description: The microcontroller adopts 8 MHz external crystals oscillator, better measurement accuracy. 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. Specification: Material: PCS Board Color: As picture show Size: Approx. 83x152x34mm/3.27x5.98x1.34inch Operating current: 9V and the stable working current about 20mA. Package Includes: 1 piece LCR ESR Transistor Meter Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement
