Introduction: NAS830 and NAS838 type are kinds of trinity half automatic range portable pocket-size digital multi-meter with stable performance, safety and reliability, based on ergonomics design, aesthetic and durable, characterized with functions of data hold, backlight, low voltage display, automatic negative display and mal-operate protections, becoming the best tool for electrical engineering. The instrument can measure parameters of DC voltage, AC voltage, DC current, resistance, temperature, diode and on-off test for circuit. Based on different models for products, the functions will also be different.
