DESCRIPTION


ST890D Smart Sensor
Introduction:

This series of instruments is a stable, highly battery-powered reliability DMM. Instruments using the full symbol, character height 26mm LCD display , a clear reading; backlit display and overload protection, so that more convenient use. This series of instruments used to measure the DC voltage and the AC RMS and average measurement, direct current and alternating current, resistance, capacitance, transistor, frequency, diode / off automatic recognition test, 20 segments analog quasi rods, high-voltage output diodes measuring. Than the traditional measurement diode provides a high voltage of 1V, so that maintenance personnel to more easily measure a variety of the LED, the whole double integral to A / D conversion as the core, is a superior performance of the work tool instrumentation, and "China Electronics Product Excellence "title. Experimental rooms, factories, radio enthusiasts and family the ideal tool.
