The Instek GDM-8034 benchtop digital multimeter (also called multitester) is an average-sensing, manual-ranging meter that measures voltage, current, resistance, capacitance, and frequency, and performs continuity and diode tests in electrical applications and educational settings. An audible continuity sensor confirms a circuit conducts electricity, and a diode test detects proper functioning of a circuit’s diodes. The 1/2″ high LCD provides high-visibility in lab and workshop settings. The meter has a compact profile with a stand that tilts the display up for easier reading or can be folded away to save room.
This average-sensing, or average-responding, meter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has a sinusoidal waveform. It is a manual-ranging meter that requires the operator to choose the appropriate operating range for the property being measured. The LCD has a 2,000-count resolution, meaning it can display up to 1,999 units (3-1/2 digits) before the operating range needs to be changed. The meter includes one pair of test leads, a 110/220V power cord, and instructions.
