This product is a miniaturized, integrative, brand new instrument for measurements of SMD resistance, capacitance and diode (RCD) parameters. In addition, it can also be used for LED, zener diode, on/off circuit and maximum 36V DC voltage measurement. This tester is a great tool for electronic factories and electronic devices maintenance. Features: The UT116A has rich functionality including automatic identification of resistance, capacitance, diode and on or off circuit; zener diode polarity/LED test, and can also measure Max.36V DC voltage. With practical features, such as auto-range, data hold, low battery indicator, LCD display with 3000 countsand auto-power off. Compact and portable, the pen can be rotated by 180°for easy reading and operation. Constructed with durable ABS housing and gold-plated tip to prevent rust. Ideal tool for electronic engineers, repairman or professionals who engaged in SMD testing.
