Digital Multimeter with AC/DC Voltage, Current, Resistance and Temperature Measurement

SZ853 Digital Multimeter with AC/DC Voltage, Current, Resistance and Temperature Measurement

The SZ853 is a portable digital multimeter designed for measuring electrical values, testing electronic components, and troubleshooting electrical circuits. It combines multiple measurement functions in a compact handheld instrument with an LCD display, a rotary selector for manual range selection, and three input terminals for connecting test leads. The instrument includes a HOLD function for retaining measurements on the display, a low battery indicator, and a folding rear stand for upright positioning on a workbench. Its protective ABS housing makes it suitable for laboratory work, technical training, classroom experiments, and general electronic testing.

Applications and Benefits:

• Measure DC voltage from batteries, power supplies, and electronic circuits.
• Measure AC voltage within the instrument's specified measurement limits.
• Measure DC current in compatible electrical circuits.
• Measure the resistance of resistors and other electronic components.
• Check circuit continuity, electrical connections, conductors, and switches using the audible continuity indicator.
• Test diodes and examine forward conduction characteristics.
• Measure transistor current gain (hFE) for compatible NPN and PNP transistors.
• Measure temperature using a compatible temperature probe.
• Measure voltage generated by electrochemical experiments using lemons, potatoes, and other suitable electrolytes.
• Investigate LED polarity, battery voltage, resistance, and basic electrical circuits.
• Support science classroom demonstrations, STEM education, electronics laboratories, and science fair projects.
• Retain measurement readings on the display using the HOLD function.
• Position the instrument upright during testing using the integrated folding stand.

Caution:

Requires one 9 V (6F22) battery for operation. Battery is NOT INCLUDED and must be purchased separately. Read the operating instructions before use. Select the appropriate measurement function, range, and input terminals before connecting the test leads. Never exceed the specified measurement limits. Disconnect power before measuring resistance, continuity, or testing components where required. Use appropriate electrical safety precautions when working with energized circuits. Adult supervision is recommended for educational use.
