auto range clamp meter HD903
General Description:
HD903 is a 4 3/4 digits AC/DC clamp meter with steady performancesafety and reliability. The clamp jaw is made of the high-quality steel products and high-quality magnetic induction components, big LCD display screen, full function and unit symbol display, wide measuring range. The instrument has a unique outline fully embodying the handheld characteristics and it is more convenient to operate.
The instrument applies high-performance A/D transformer, and all components are SMD-surfaced. Every range of the meter has overloading protection, not to damage.
AC/DC current is measured through the clamp jaw, but the rest is through test lead input and is auto ranging which can test AC voltageDC votlgeFrequencyDutyResistanceCapacitanceDiode and Continuity.
The instrument has button of "DCA 0 ADJ" in order to return to zero before measuring big current.
