ICE Supertester 680 R is a legendary Italian analog multimeter that has been in production with essentially the same design since the late 1960s. It is highly regarded by electronics hobbyists and professionals for its precision, featuring a unique 100° mirrored scale that helps eliminate parallax errors. Key Technical Specifications Sensitivity: DC and 4,000 ±1% on DC and ±2% on AC ranges. Measurement Ranges: Up to 1000V DC and 750V AC. Up to 5A AC/DC. Resistance: Includes a "LowOhm" test range from 0 to 500 Additional Tests: Diode, transistor, LED, and battery testing. Older versions (like the VI series) used a now-obsolete 3V 2R10 battery , while modern versions typically use a 9V battery Reviews & User Perspectives Reviewers from forums like and vintage tech collectors highlight the following: EEVblog #634 - Analog Multimeter Teardowns

is a legendary analog multimeter manufactured by the Italian company I.C.E. (Industria Costruzioni Elettroniche) . Known for its precision, durability, and reliability, the 680 R series became a staple for electronics technicians and engineers throughout Europe and beyond for decades. Even today, the analog nature of this device makes it superior to digital multimeters for observing voltage fluctuations or testing components like capacitors. Measurement Ranges: Up to 1000V DC and 750V AC
The is more than just a measurement tool; it is a landmark in the history of electrical engineering . Developed in Italy by Industria Costruzioni Elettromeccaniche (ICE) in Milan starting in the 1960s, this professional analog multimeter has remained in production for decades due to a design so functional that improvements are difficult to justify. A Legacy of Italian Precision Supertester 680 R
The Supertester ICE 680 R has seen variations in its power supply over the years. Earlier versions (like the 5th series) typically used a single 3V battery, while later models (6th and 7th series) use either a 1.5V LR14 battery (type C "mezza torcia") or a standard 9V battery. Always check the battery compartment or your specific manual to confirm.
